Updates

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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).

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.

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.

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".

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.

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).

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.

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.

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.

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.

The Feedback page now has an "Upcoming Updates" section at the bottom that lists what we are currently working on. Generally, only items that will take some time to complete are listed here. Features and fixes may still be released without being listed here, so please keep that in mind.

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 (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).

Related features: Custom calendars

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.

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.

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.

Even if you leave the page open, the latest stream/video information is now fetched automatically every 10 minutes. The date you are viewing and your scroll position are preserved. The same content as the manual refresh (🔄 button) is applied.

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.

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).

When there are new updates, a count badge now appears on the "Updates" button in the header. If you have never opened the page before, the badge shows the total count so far. Opening the Updates page clears the badge, and the items you had not seen yet are highlighted in light yellow.

A refresh button was added to the right of the "Feedback" button at the top right.

The Day and Week views now show a red dot and line at the current time. The List view also gets a marker like "Now 15:32" inserted into today's list. You can instantly see where the current time falls among the streams.
