Fixed an issue where search and page loading could temporarily slow down

No.61
NewPCMobile

Search and page loading could occasionally take a long time or fail to return results. Sorry for the inconvenience. This has been fixed, and pages should now load more reliably than before.

Choose the time zone for schedule times

No.60
NewPCMobile

Added a "🌐 Time zone" selector to the sidebar. Stream and video times have always been shown automatically in your device's local time — now you can also switch them to the local time of any region you choose from a worldwide list. By default it stays on "Auto (device setting)" and works exactly as before. While a time zone is selected, a 🌐 badge appears in the header, and the setting also applies to date ranges in search, member pages, and the songs list. The setting is saved on your device only. This feature was added by request — thank you!

No.59

Archives of alumni members are now available

No.58
NewPCMobile

We now list past streams and videos of 11 alumni members and members who have ended streaming. They appear in the member list with "Alum" / "Streaming ended" badges, and you can look back at their streams in the past calendar, search, and member pages. Note: tags (genres) and collab info for these archives will continue to be refined over time. If you spot an error, please let us know via "🚩 Spotted an error?" in the detail window.

You can now report errors right from the detail window

No.57
NewPCMobile

We've improved the "🚩 Spotted an error? Let us know" button in the stream/video detail window. Instead of jumping to the request page, tapping it now opens a small form right there — just pick the type of error and send. - Types: "Wrong tag / genre," "Wrong collab info," "Wrong time / title / info," or "Other" - Adding details is optional (though always appreciated) - The stream/video info is attached automatically, so there's no need to copy titles - Replies can be checked on the request page, as before - The same form is available in the anniversary detail window - The button has also moved to just below the "Open video" button, so it's easier to find Since we've just expanded the archive to roughly 100,000 entries, some tags or collab info may still be wrong. If you spot anything, we'd love to hear from you.

Past archive import complete (EN, ID & official channels)

No.56
NewPCMobile

We've finished importing past streams and videos for hololive EN and ID talents and the official channels. This means the archive now covers every currently active talent and official channel, all the way back to their debuts and channel launches (the oldest entries go back to September 2017). - Browse old streams and videos freely from the calendar, list, search, member pages, and tag search - Official channels include the "Blue Journey" music project - "🎲 Throwback" and the "Games played" list on member pages now draw on the full archive too On July 11 we estimated everything would be in place around August — we finished ahead of schedule. In total, roughly 98,000 past streams and videos have been added. - We're also preparing past data for graduated talents, while working out how best to present it (Some older streams may have been made private or deleted, in which case their thumbnails or links may not display correctly.)

[Experimental] Added a "Flow" mode to Throwback

No.55
NewPCMobile

After you draw a past stream with "🎲 Throwback," the detail window now has a "🎠 Flow" button. Tap it to open a "watch mode" where thumbnails of random past streams and videos flow by automatically. Just leave the calendar open and rediscover old streams. - Tap any thumbnail to open its details - Flows bottom-to-top on portrait screens, right-to-left on landscape - Pause with "⏸ Pause" (top right). If you use "reduce motion," it starts paused — press "▶ Play" to flow - It keeps loading new streams as it goes, so the same one won't keep repeating (This is an experimental feature. The speed, look, and controls may change based on your feedback — we'd love to hear what you think.)

Added a "Draw 10" mode to Throwback

No.54
NewPCMobile

After you draw a past stream with "🎲 Throwback," the detail window now has a "🎲 Draw 10" button. Tap it to see 10 random streams and videos from 6+ months ago as thumbnails at once. Tap any of them to open its details, or "Draw 10 more" for a fresh set. A nice way to idly rediscover old streams.

Added an "Original + holodori songs" page (holodori = new mobile rhythm game)

No.53
NewPCMobile

Added a page to browse hololive original songs (MVs & music videos) together with cover songs featured in holodori (hololive Dreams), a new mobile rhythm game. Open it from "🎵 Original + holodori songs" in the sidebar. - Filter by member and type (All / MV only / Non-MV), and sort newest or oldest - Tap "holodori only" to show just the songs featured in the game (covers included) - Switch between list and tile (larger images) views - Shows the number of songs matching your filters - Tap the thumbnail to watch on YouTube, or tap elsewhere to open the detail window - You can also open a member's songs from "🎵 Original songs" on their page (We've gone back and added older songs too, covers included.)

Related features: Original songs

Added a "Games played" list to member pages

No.52
NewPCMobile

Each member page now shows a list of the games that member has played. Games are grouped by series — tap one to expand into individual titles — and the years played are shown too. You can also tap a game name to filter the "Past streams & videos" section on that page down to just that game (use the clear button to reset). (Compiled from streams each member hosted. Since we aggregate across past archives, games going back to their debut are included.)

Related features: Member pages

Fixed an issue where some member pages could fail to load

No.51
NewPCMobile

On some member pages, the "Upcoming streams" or "Past streams & videos" sections could occasionally take too long to load, causing the whole page to fail to display. Sorry for the inconvenience. We've fixed this. We also made it so that even if a section fails to load, the page itself still shows, and only the affected section displays "Couldn't load" — the page will no longer go blank. (This surfaced as we added a large volume of past archives.)

Share search results by URL, or play them as a YouTube queue

No.50
NewPCMobile

We added three buttons to the top right of the search results. - "▶ Play on YouTube" opens the current results as a YouTube queue, keeping the exact order shown. Great for things like playing a talent's singing streams back-to-back from the oldest (up to 50 items; upcoming streams and Twitch are not included). - "🔗 Copy search URL" copies a URL that carries your current search filters. Anyone who opens it sees the same search — perfect for sharing a fun combination, or bookmarking searches you use often. - "𝕏 Share on X" posts the search URL straight to X.

Minecraft tags are now organized by server event

No.49
NewPCMobile

We reorganized the Minecraft tag (about 4,700 entries) so you can browse by hololive server event. - Open "Minecraft" in tag search and you'll find 13 events underneath — Holo Server Hardcore, Holo Dragon Minecraft, Money-Making Survival, hololive Land, and more. - The same events are also reachable from the "Projects" tag as "… (Project)," so you'll land on the same streams from either side.

Watchalongs of movies and anime are now searchable by title (plus display improvements)

No.48
NewPCMobile

We've added per-title tags for movie and anime watchalongs, including members-only ones. - Around 190 works are newly tagged. You can now find them by title from tag search — "Die Hard," "Toy Story," and so on. For series, sequels come up together. - We also adjusted the detail window so the description is easier to read. Previously you had to make the window taller before the description would show much of anything; now the thumbnail shrinks automatically when the window is small, so the description keeps a usable height. If it still doesn't fit, you can scroll the whole window. - And we added the red "current time" line to the Tiles view (the same one the Calendar view has).

Related features: Search (tags)

Our archive of past streams is now even richer

No.47
NewPCMobile

We've added past streams and videos from hololive JP and DEV_IS talents, going all the way back to their debuts. You can now follow older streams and videos from the calendar, list, and tag search. - We'll keep filling in past data. The planned order is: EN / ID talents → official channels → graduated talents. (Importing past data takes time, so entries will keep appearing gradually.)

🎲 "Throwback" — dig up a random past stream

No.46
NewPCMobile

We added a "🎲 Throwback" button to the right of the search button on the home page. - Press it to pick one random stream or video from over six months ago and open it in the detail window. Great for when you can't decide what to watch, or when you want to unearth an old favorite. - Use "🎲 Draw again" in the window that opens to keep drawing (you won't get the same one twice in a row). - We've imported past archives going all the way back to each talent's debut, so you might stumble onto an unexpected gem from years ago. Note: Shorts are excluded.

More tag cleanup — it's now easier to find works by individual title

No.45
NewPCMobile

Since we let you find games by genre on July 14, we've continued cleaning up the tags. - You can now find series such as Dragon Quest, Final Fantasy, and Super Mario by their individual titles (for example, we separate numbered entries and remakes, like "Dragon Quest XI" and "Dragon Quest III HD-2D"). Filter by the higher-level "Dragon Quest series" and it brings up the individual titles beneath it as well. - We reviewed tags that had been applied by mistake, improving search accuracy. - We import past streams and videos at a rate of several thousand a day, and we'll keep tidying this up over time. If you spot a mistake, please let us know from "Requests" in the header — it really helps.

Add Holo Calendar to your home screen and use it like an app

No.44
NewMobile

You can now add Holo Calendar to your phone's home screen and open it full-screen like an app. How to add: on Android (Chrome), choose "Add to Home screen" or "Install app" from the menu; on iPhone (Safari), tap the Share button and choose "Add to Home Screen". Note for iPhone: the home-screen version stores its settings (such as your favorite members) separately from Safari. To carry your current settings over, use "Sync settings across devices" in the sidebar and enter the issued code in the home-screen version.

From a stream's details, you can now jump to that day's calendar or a tag search

No.42
NewPCMobile

From a stream or video's details window (the panel that opens when you click it), you can now follow where it leads — along the timeline or by its subject. - We added a "📅 View this day" button. Pressing it moves the calendar to the day that stream took place and scrolls to around its time, so you can see "what else happened on the day of this stream" in a single click. - The tags shown in the details window (a path like "Games › FPS / TPS › Apex Legends") are now clickable. Pressing one opens a search filtered by that tag — "I want to see more streams with this tag" in one click. Press a higher-level tag (say "FPS / TPS") and it brings up the streams tagged with individual games beneath it as well.

You can now find games by genre

No.41
NewPCMobile

You can now find games by genre in tag search — "Horror Games", "RPG", "FPS / TPS", and so on. Until now you could only narrow things down by an individual game name such as Minecraft, so there was no way to ask "is anyone playing something horror-ish?" - We organized games into 25 genres (Horror Games, FPS / TPS, RPG, Action / Adventure, Survival / Crafting, Rhythm Games, Racing Games, Fighting Games, Puzzle, Visual Novel / Mystery, Table / Card / Gambling, Mobile / Gacha Games, Co-op / Party Games, Simulation, Roguelike, Strategy, MOBA, Sports Games, Quiz / Trivia, Shoot 'em up, Rage / Silly Games, Anime / Manga / Movie Based Games, and more). - Choosing a genre also brings up streams tagged only with an individual game beneath it (filtering by "RPG" includes streams tagged just Dragon Quest, Final Fantasy, or Pokémon). - A single game can carry more than one genre (Slay the Spire, for example, can be found under both "Roguelike" and "Card Games"). - Genres generally follow the game's own genre. That said, the fewer streams a title has, the more likely its genre is wrong — some titles were classified by inferring from the stream titles. - We are also importing past streams and videos at a rate of several thousand a day, so some have not been checked yet. We keep tidying this up day by day. - Some series deliberately have no genre (series like Mario, where each title has a different genre, and things like VRChat, which no single genre describes). If you spot a mistake, please let us know from "Requests" in the header — it really helps.

Search is easier to use on phones

No.40
NewPCMobile

On phones, the search filters (period, member, status, genre, tag) were taking up the top half of the window, leaving almost no room for the results. We fixed three things. - The filters now start collapsed, roughly doubling the space given to your results. While collapsed, a single line still shows what you are filtering by (for example "Filters: Mario series"), and you can tap it to open the filters again at any time. - The tag and member panels now have a "Show results (N)" button at the bottom. Until now the panel stayed on top of your results, and the only way to dismiss it was to tap outside of it. - Your phone's Back button now closes the search window. Previously it took you away from the calendar entirely. If you have a stream's details open on top of search, Back closes the details first, then search. The desktop layout is unchanged (the browser Back button closes the window there too, in the same way). This came from a user request — thank you.

The calendar now takes up more of the screen on phones

No.39
NewMobile

On phones the header was taking up about a third of the screen, leaving only half the view for the calendar itself. We made the header compact, so the calendar now gets much more room. - The things you use most (day/week/month, moving between dates, the calendar/list/tile switch, and search) stay visible at all times, just as before. - Everything else (sidebar, help, changelog, requests, refresh, theme, language, and your oshi's next stream) is now behind the "More ▼" button in the top right. Nothing has been removed. - The layout on desktop is unchanged. This came from a user request — thank you.

You can now search by tag

No.38
NewPCMobile

We added a "tag" filter to the search window, so you can find streams and videos by game title, project name, or recurring show name (for example "Minecraft", "Grand Theft Auto", or "Watch-along"). Note: for game and show titles we also match the nicknames and abbreviations people actually use, not just the official name — searching for "GTA" brings up Grand Theft Auto streams, and "MHW" brings up Monster Hunter: World. - Type in the tag box to narrow the candidates. Click it while empty to drill down from broad categories (Games → Horror games → Chilla's Art, and so on). - Choosing a broad tag also brings up streams tagged with anything beneath it. Filtering by "Games" includes streams tagged only with an individual game name. - You can search by tag alone, without entering a keyword. - Each stream/video detail window now shows the tags it carries. Tags are applied automatically, so occasionally one may be missing or wrong. We are also importing past streams and videos at a rate of several thousand a day, so depending on when an item was imported it may have no tags yet, or the wrong ones. We keep improving the accuracy of the automatic tagging, and we correct entries by hand where needed. If you would like a tag added, or you spot a mistake, please let us know from "Requests" in the header — it really helps.

We reworked how genres are organized

No.37
NewPCMobile

We rebuilt how genres are detected so they better match what streams actually are. - "Music & Dance" is no longer one lump: it is now split into "Karaoke", "Music videos", "Dance", and "3D live". - We added "Projects" and "Recurring series". - "Milestones", "Endurance", "3D", "Shorts", and "Official" are no longer genres. Shorts can still be filtered from the status toggles, as before. - Detection accuracy improved too: many streams that used to fall into "Other" now land in the right genre. If you had narrowed the view to particular genres, your choices carry over automatically (for example, if you were showing "Music & Dance", all four of the new genres it was split into are shown). We are also importing past streams and videos at a rate of several thousand a day, so depending on when an item was imported its genre may not match the actual content. We keep improving the accuracy of the automatic classification, and we correct entries by hand where needed. If you spot a mistake, please let us know from "Requests" in the header — it really helps.

The site has a new address (URL)

No.36
NewPCMobile

The official address of Holo Calendar is now https://holo-calendar.com. - If you have bookmarked the site: the previous address (holo-calendar.vercel.app) is automatically redirected to the new one, so it will still work. We recommend updating your bookmarks to the new address. - If you saved display settings, favorites, or custom calendars (important): because of how browsers work, settings are stored separately for each address. This means the members you chose to display, your favorites, your custom calendars, and which changelog entries you have read are not carried over to the new address automatically. Your data has not been deleted. A notice at the top of the home page lets you press "Restore my settings" to bring everything back (available until September 30, 2026). - If you use calendar integration (iCal): the feed URL you already registered will keep working, but it still points to the old address. We recommend getting the new URL from "Calendar integration" in the sidebar and subscribing again.

Past archived streams now appear too (experimental)

No.35
NewPCMobile

Until now, only streams and videos from July 1, 2026 onward were shown. Experimentally, we now also show older archived streams from before that date. - Starting with the past data we have already collected, they appear on the calendar, in search, and on member pages. You can go back to dates before July. - We are adding past data little by little in the background, and about 27,000 items have been added so far. Everything should be in place by around August 2026, and the range you can go back to — and the number of streams shown — will keep growing day by day. - We are currently adding data for members who are active now. Once that is complete, we also plan to add data for members who have graduated. - Some older streams may have been made private or deleted, in which case their thumbnails or links may not display correctly.

You can now return to your search results after opening a detail window

No.34
NewPCMobile

When you searched for streams and videos and opened a detail window from the results, the search window used to close, so you had to search again to see other results. Now, closing the detail window (×, clicking the background, or the Esc key) takes you right back to your search results. Your keywords, filters, and scroll position are kept, so you can open one result after another to check them. We also made the search button in the header easier to find. You can search all the way back through past archives — please give it a try.

Collabs where your members appear as guests now show on the calendar

No.33
NewPCMobile

When you narrowed the calendar down to certain members, collab streams where those members appeared as a guest were missing. For example, if you displayed only your oshi, a collab hosted on someone else's channel would not appear even when your oshi was in it. These streams now show up. Note: search and member pages already included guest appearances, so the calendar now behaves the same way. The "next stream from your oshi" indicator in the header also picks up guest appearances now.

Fixed the page jumping around while loading

No.32
NewPCMobile

Fixed a problem where the page shifted around right after it opened. - On PC, the calendar was pushed down when the date appeared in the header. - On smartphones, the sidebar (member list) appeared briefly and then closed, widening the calendar. Both were momentary movements while loading, but they could make a button move just as you were about to tap it, so the layout now stays put from the start. Thumbnails in the "Live now" bar at the top also appear faster than before.

New LIVE bar shows who's streaming right now

No.31
NewPCMobile

While someone is live, a LIVE bar with thumbnails of ongoing streams now appears under the header. - Whatever date or layout you're viewing, you can instantly see who's live right now. Click a thumbnail to go straight to the stream. - Streams from members you've hidden in the sidebar are not shown. Your oshi's (★) streams stand out with a gold border. - You can collapse the bar with ▲ (remembered for next time). It doesn't appear when no one is live.

Four small improvements

No.30
NewPCMobile

We added four small quality-of-life improvements. - Tile size switch: a "Tile size: Large/Small" toggle at the top right of the Tiles layout. "Small" fits more tiles on screen (remembered on your device). - Keyboard shortcuts (for PC): ←/→ to move, T for today, D/W/M for day/week/month, 1/2/3 for calendar/list/tiles, S for the sidebar, R to refresh, / to search, O for oshi-only, and Esc to close windows. Press Q anytime to see the full list. - Oshi birthday countdown: with an oshi (★) set, the header shows their nearest birthday as "🎂 in N days". Click it to jump to that day. - Jump to top / bottom: ▲▼ buttons at the bottom right of long-scrolling screens (list, tiles, updates, member pages). On the PC calendar they sit at the bottom of the right arrow rail.

Member pages are here

No.29
NewPCMobile

We added a dedicated page for each member where you can see their upcoming streams, past archives, and anniversaries in one place. - Open it by clicking the member's name (👤) in a stream/video's detail window (it opens in a new tab, so your calendar stays as it is). - Streams where the member appears as a guest are also listed with a "Guest" label. - Past archives go back further than the period shown on the calendar.

Search streams and videos

No.28
NewPCMobile

Use the 🔍 button in the header (or Ctrl+F / ⌘F on Mac) to search streams and videos by title or member name. - Separate words with spaces to require all of them (e.g., "Minecraft endurance"), and prefix a word with "-" to exclude it (e.g., "karaoke -members"). - You can filter by period, members (multiple selectable), and status. Filtering by members also includes streams where they appear as a guest. - It searches all time (streams/videos from before the calendar display period also appear). Results are shown 50 at a time, newest first, with "Show more" to load more. - Your recent keywords are remembered on this device only, so you can quickly reuse them. - See "About search" on the Help page for details.

Share your member selection with friends

No.27
NewPCMobile

Use "Copy share URL of current view" in the sidebar to turn your current member selection into a URL you can share. - Whoever opens it sees it as a shared view, and can adopt it with one click via "Save as a custom calendar" (just opening it doesn't change their settings). - Great for introducing your favorite unit's calendar on social media, for example. - The URL contains only the member selection — it doesn't reveal who shared it.

No.26
NewPCMobile

Add the URL created from "Calendar app sync" in the sidebar to Google Calendar or other calendar apps, and your oshi's (★) streams and anniversaries will automatically appear in the calendar you already use. - This includes streams where your oshi appears as a guest. - For Google Calendar, just paste the URL into "Other calendars" → "+" → "From URL". The same URL also works with iPhone's Calendar and Outlook. - Only the title, time, and watch link are added to your calendar. Out of consideration for rights holders, thumbnails, descriptions, and other data are not included. - Updates may take a few hours to a day to appear (it depends on how often your calendar app refetches — it is not real-time). - The URL is personal to you — please don't share it. If you accidentally do, use "Regenerate URL" to invalidate the old one.

Added an easy way to let us know about mistakes

No.25
NewPCMobile

We added a "Spotted an error? Let us know" link at the bottom of the detail windows for streams, videos, and anniversaries. - Clicking it opens the Feedback page with the item's info already filled in — just add what you noticed and send. - Anything helps: genre detection mistakes, wrong times, typos in titles, and more. - When you go back to the calendar from the Feedback page, everything stays exactly as you left it (the date you were viewing and the open window).

Filter streams and videos by genre

No.24
NewPCMobile

You can now narrow down the calendar using genres automatically detected from titles and other data. - As of this release, there are 11 genres — Music & Dance, Games, Chatting, Collabs, Watch-along, Milestones, ASMR, Endurance, Shorts, Members-only, and Other — and one stream can have multiple genres (e.g., a game endurance stream gets both "Games" and "Endurance"). We plan to add more genres as needed. - Toggle them via "Genre filter" in the sidebar; the setting syncs across devices. Detected genres are also shown in each stream/video's detail window. - Detection is automatic and may occasionally differ from the actual content. We will keep improving its accuracy.

Related features: Sidebar, detail window

Added a Terms of Use & Privacy Policy page

No.23
NewPCMobile

We added a page that brings together the terms of use, privacy policy, and disclaimer for this service. - It covers the unofficial fan-made nature of this service, how copyrighted content is handled (including a contact route for rights holders' removal requests), our data sources, how cookies and browser storage are used, access logging, and disclaimers. - You can find it at the bottom of the sidebar on the calendar screen, or via the link at the bottom of the Help, Updates, and Feedback pages.

No.22
NewPCMobile

You can now mark the members you support most as "favorites". Press the ☆ to the right of each member under "Members" in the sidebar (also available next to the member name in a stream/video's detail window). With favorites set: - Your favorites' streams and videos are highlighted with a gold border and a ★ in every layout. This applies not only to their own streams but also to streams where they appear as a guest (collab streams now also show small guest icons). - On days when the Month calendar cannot show every icon, your favorites' icons are displayed with priority. - "★ Favorites only" at the top of the sidebar filters the calendar to events related to your favorites. - Your favorite's next schedule appears at the top of the screen; click it to jump to that day. While a favorite is live, a 🔴 appears on the browser tab. - Favorites are carried over to other devices via "Sync settings across devices".

Renewed the Month × Calendar view on PC (two-pane layout)

No.21
NewPC

We rebuilt the Month × Calendar view on PC into a two-pane layout: a month calendar on the left and the selected day's schedule on the right. - Each day cell shows its event count (red if something is live), anniversaries, and the icons of members with streams/videos that day. When a member has multiple streams on the same day, their icon is now shown only once (the ring color represents their most important status of the day). - Click a date or "+N" to show that day's schedule (time, member, title) on the right. The list stays in view while you scroll, so you can quickly browse through the days of the month. - The calendar now stretches to fill the window height, and the number of icons shown per day adjusts automatically to your screen size. - Clicking an icon directly still opens the detail window, and "Open day view →" jumps to that day's Day view.

English display support (language switch)

NewPCMobile

Holo Calendar now supports English display. - Use the "JP→EN" button in the header to switch between Japanese and English at any time. Your choice is remembered on this device. - On your first visit, if your browser language is not Japanese, the app automatically starts in English (you can switch back to Japanese from the banner at the top). - Not only the calendar itself but also the Help, Updates, and Feedback pages, as well as member names, group names, and anniversaries, are displayed in English. Stream/video titles and descriptions are always shown as they appear on YouTube/Twitch. *Stream and video times have always been shown in your device's local time zone (viewers outside Japan see times in their local time).

Renewed the Help page

No.19
NewPCMobile

We rebuilt the Help page to be easier to read and added explanations of recently added features. - The first half now covers usage common to both PC and smartphones, and the second half covers PC-specific and smartphone-specific usage. Line and item spacing were also increased for readability. - A wiki-style table of contents was added. On PC it is always visible on the left side of the screen; on smartphones, open the "Table of contents" above the text. Clicking a chapter or question jumps directly to it, and as you read, your current position is highlighted in the table of contents. - When the Help page is updated, a count badge now appears on the "Help" button at the top of the calendar. If you open the Help page while the badge is shown, the updated chapters are marked in the table of contents so you can see what changed at a glance. *With this release, all chapters count as updated once, so everyone will see the badge one time. Thank you for your understanding.

Added "PC / Mobile" tags and filtering to the Updates page

No.18
NewPCMobile

As the number of updates has grown, each update now has tags such as "PC" and "Mobile", and you can narrow down the list with the buttons at the top. - Use the "All", "PC", and "Mobile" buttons to choose which updates to show (multiple can be selected). Your selection is remembered on this device and applied on your next visit. - Updates you have not checked yet get a "New" tag and are always shown regardless of the filter (their cards are highlighted in yellow). Once you view the Updates page and return to the calendar, the "New" tag is removed. More tags will be added over time.

Move between dates with edge buttons or swipes

No.17
NewPCMobile

Previously the only way to move back and forth (previous/next day, week, or month) was the "←" "→" buttons at the top of the screen, which were a bit hard to reach. You can now also: - On wide screens such as PCs: click the faint arrow buttons (‹ ›) at the left and right edges of the calendar, like turning pages in an e-book reader. - On narrow screens such as smartphones: swipe the calendar left or right (swipe left for next, right for previous). In horizontally scrollable layouts such as the Week × Calendar view, a swipe only turns the page when the content is already scrolled to its left or right edge. The "←" "→" buttons at the top continue to work as before.

Improved the Month × Calendar view (experimental)

No.16
NewPCMobile

We improved how the Month view looks when "Calendar" is selected. Previously each day could only show a small amount of information, which made it hard to use. It now works as follows: - On wide screens such as PCs: each day is filled with the icons of members who have streams or videos that day. The ring color of each icon tells you whether it is live, upcoming, ended, or a video, so you can see at a glance whether your oshi has something that day. Tapping an icon opens the detail window. - On narrow screens such as smartphones: each day shows its number of events (in red if something is live), plus a 🎂 on days with anniversaries. Tapping a date opens that day's schedule below the grid. This view is still experimental, and we will keep improving it.

In the Day, List, and Tile views, clicking (tapping) a thumbnail image now takes you directly to the video/stream page without opening the detail window. Clicking anywhere else still opens the detail window as before.

Custom calendars now also save the view range and collapse state

No.13
NewPCMobile

Custom calendars now also save the view range (Day/Week/Month). In addition, if you save while "Expand all" or "Collapse all" is selected in the List or Tile view, that state is saved and restored too (collapsing only some individual days is not saved).

In the List and Tile views for Week/Month, "Expand all" and "Collapse all" buttons were added at the top to open or close every displayed date at once. Date headings also got a light blue background and more height so they are easier to notice while scrolling.

Collapse days in the List and Tile views

When using the List or Tile view in Week or Month view, clicking a date heading now collapses that day's contents. Click it again to restore. Useful when you want to focus on specific days only.

Added the thumbnail-focused Tile view

No.10

We added "Tiles", a list format that shows stream/video thumbnails at a larger size. Switch with the "Calendar", "List", and "Tiles" buttons to the right of the date picker. It also shows start–end times (for ended streams) and the upcoming/live/ended/video category.

You can now post to X (formerly Twitter) from a stream/video's detail window, in the same format as YouTube's share button (title + link). To the right of "View channel" there are two buttons: "Share via X app" and "Share via browser". Use the former if you are logged in on the X app, or the latter if you are logged in on your browser.

Support for members with registered Twitch channels

No.6
NewPCMobile

For members who have a Twitch channel registered, their Twitch "live" and "ended" streams now also appear on the calendar. The purple dot to the left of a member's name marks a Twitch stream. Twitch schedules (upcoming streams) are not supported. Also, since stream endings are detected by checks every few minutes, the end time may be off by a few minutes (this is also noted in the detail window).

A refresh button was added to the right of the "Feedback" button at the top right. Pressing it refetches only the latest stream/video information (descriptions, statuses, etc.) while keeping the date you are viewing.

The open/closed state of the left sidebar (member filters, etc.) is now remembered, and the calendar opens in the same state on your next visit. On narrow screens such as smartphones, the sidebar still always starts closed so the calendar stays easy to see.
