How to use Holo Calendar

About this page

Holo Calendar is an unofficial fan-made app developed and run by a single individual, with no affiliation with hololive production or its talents.

It shows the schedule of hololive talents' YouTube streams and videos (plus Twitch streams for members with a registered Twitch channel) in an Outlook-style calendar, a simple list, or a thumbnail-focused tile layout similar to Holodule (schedule.hololive.tv). You can check multiple talents' schedules side by side.

It works on both PC and smartphones. Some displays and controls differ depending on screen size, so the first half of this page explains usage common to both, and the second half explains PC-specific and smartphone-specific usage.

This app is developed with Claude Code, Anthropic's AI coding tool.

We are gradually adding past archives, too (experimental). The past data we have already collected can be viewed by going back through the dates, and the rest is added little by little (everything should be in place by around August 2026).

See our Terms of Use & Privacy Policy.

Screen basics (PC & smartphone)

• Use "Day", "Week", and "Month" at the top to switch the range. "←" "→" move back and forth, and "Today" returns to the current date. Click the 📅 icon to pick a date directly.
• The "Calendar", "List", and "Tiles" buttons to the right of the date picker switch the main layout. "Calendar" shows blocks whose length matches each stream's duration, "List" is a simple chronological list of fixed-height rows, and "Tiles" is a list with large thumbnails. Your choice is remembered on this device and used next time.
• In the Day/Week "Calendar" layout, each stream appears as a block whose length matches its start–end time. Overlapping streams are placed side by side.
• Click a block to open a detail window with the thumbnail, description, and more. However, clicking the thumbnail image itself (in the Day, List, and Tile views) takes you directly to the video/stream page without opening the detail window.
• Anniversariessuch as birthdays and debut days appear as light purple bars at the top of the day (with an "Nth Anniversary" label). Click one to see related members and details.
• In the List or Tile view for Week/Month, click a date heading (e.g. "2026/07/06 (Mon)") to collapse that day's contents; click it again to restore. The "Expand all" / "Collapse all" buttons at the top open or close all displayed dates at once.
• When today is displayed, a red marker shows the current time (a red dot and line in the Day/Week views, and a "Now hh:mm" divider row in the List/Tile views).
• While someone is live, a LIVE bar (🔴 LIVE) appears under the header with thumbnails of ongoing streams. Click a thumbnail to go straight to the stream. You can collapse it with ▲, and members hidden in the sidebar are not shown.
• Click a member's name in the detail window to open their member page(profile, upcoming streams, anniversaries, and past archives in one place) in a new tab. It includes guest appearances, and "View in calendar" jumps to a calendar filtered to just that member.
• Use the 🔍 button in the header (or Ctrl+F / ⌘F on Mac) to search streams and videos by title or member name. It searches all time, and clicking a result opens its detail window. It also supports multiple space-separated keywords (all must match), "-keyword" to exclude, and filtering by period, member, and status. To use the browser's built-in find-in-page instead, press Ctrl+F again while the search is open.
• Press the 🔄 button in the header to refetch only the latest stream/video information (descriptions, statuses, etc.) while keeping the date you are viewing. The page also refreshes automatically every 3 minutes while it is open.
• The icon near the right end of the header (🖥️/☀️/🌙) switches the color scheme between Auto (follow your device), Light, and Dark. Your choice is remembered on this device.
• The "EN→JP" button in the header switches the display language between Japanese and English. On your first visit, the language is detected automatically from your browser settings, and your choice is remembered on this device. Note that stream/video titles and descriptions are always shown as they appear on YouTube/Twitch.

About search (PC & smartphone)

• How to open: the 🔍 button in the header, or Ctrl+F (⌘F on Mac).
• Basic search: type part of a title or a member name and results appear as you type. Member names match in both Japanese and English. Clicking a result opens its detail window.
• It searches all time — past streams and videos (archives) also appear. Past items now show on the calendar as well (added gradually).
• Multiple keywords (AND): separate words with spaces to require all of them. Example: "Minecraft endurance". You can also combine a member name with a keyword.
• Exclude (-keyword): prefix a word with "-" to exclude it. Example: "karaoke -members".
• Filters: below the search box you can filter by period, member, and status (Live/Upcoming/Ended/Video). You can select multiple members, and the results also include streams where they appear as a guest.
• Show more: results are shown 50 at a time, newest first. Use "Show more" at the bottom to load more.
• Search history: your recent keywords (up to 10) appear when you open the search box and can be clicked to search again. History is stored only on this device and can be cleared anytime with "Clear".
• To use the browser's built-in find-in-page, press Ctrl+F (⌘F) again while the search window is open.

What the colors mean (PC & smartphone)

A purple dot to the left of a member's name marks a Twitch stream (to distinguish it from YouTube streams).

Sidebar features (PC & smartphone)

• Groups: toggle visibility for whole groups (generations, units, etc.) at once. There are also "All" and "Clear" buttons.
• Status filter: toggle "Live", "Upcoming", "Ended", and "Video" individually. This also has "All" and "Clear" buttons.
• Calendar app sync: create a URL from "📅 Calendar app sync" and add it to Google Calendar or other calendar apps to see your oshi (★) streams and anniversaries in the calendar you already use (guest appearances included). 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. The URL is personal — don't share it with others (regenerating it invalidates the old URL).
• Genre filter: narrow the view by genres automatically detected from titles and other data (Music & Dance / Games / Cooking / Chatting / Collabs / Watch-along / 3D / Milestones / Limited-time events / Totsumachi / ASMR / Endurance / Official / PR / Shorts / Members-only / Other). Detection is automatic, so it may occasionally differ from the actual content. The detected genres are also shown in each stream/video's detail window.
• Custom calendars: see "About custom calendars" below.
• Members: toggle visibility per member.
• Favorites (★): press the ☆ to the right of each member under "Members" to mark them as a favorite (also available next to the member name in a stream/video's detail window). Favorites' streams and videos —including streams where they appear as a guest— are highlighted with a gold border and a ★, and their icons are shown with priority in the Month view. Use "★ Favorites only" at the top of the sidebar to filter to favorites-related events, and the header shows your favorite's next schedule (a 🔴 appears on the browser tab while a favorite is live). Favorites are included in "Sync settings across devices".
• Sync settings across devices: issue a sync code for transferring your current view settings to another device (smartphone, PC, etc.).
• Use "Hide sidebar" / "Show sidebar" in the header to toggle the sidebar — useful when you want the calendar to fill the screen.

About custom calendars (PC & smartphone)

• A feature that saves your member selection and view settings together under a name, so you can restore them later with one click. Handy when you switch between several patterns, such as an oshi-only set or per-generation sets.
• The following are saved:
  • The member checkboxes selected in the sidebar
  • The layout (whether "Calendar", "List", or "Tiles" was selected)
  • The range (whether "Day", "Week", or "Month" was selected)
  • If you save while "Expand all" or "Collapse all" is selected in the List or Tile view, that open/closed state is saved too. Collapsing only some individual days is not saved (the affected dates change with the displayed period, so it would lose its meaning).
• To save: arrange the view the way you like, enter a name in the "Custom calendars" box near the bottom of the sidebar, and press "Save current view".
• Share URL: use "Copy share URL of current view" to turn your current member selection into a URL you can share with friends. Whoever opens it sees a shared-view banner and can save it as their own custom calendar with one click (just opening it doesn't change their settings). The URL contains only the member selection — it doesn't reveal who shared it.
• To restore: click a saved name in the list to apply those settings.
• To rename / delete: use the ✎ button next to each item to rename it, and the × button to delete it.
• Up to 30 can be saved per device (browser).

About feedback & bug reports (PC & smartphone)

• Use the "Feedback" button in the header to send improvement requests and bug reports — no login required.
• Submissions are visible only to the administrator and are never shown to other users.
• Replies from the administrator can be viewed by revisiting the Feedback page in the same browser you sent from. Note that you cannot view your submissions/replies from another browser or device, or after deleting cookies.
• When you have an unread reply, a count badge appears on the "Feedback" button when you open the calendar. Opening the Feedback page marks it read and clears the badge.
• Please understand that we may not be able to address every request.

Using on PC

Content specific to mouse-operated environments such as PCs.

• Keyboard shortcuts are available — press Q anytime for the full list: ←/→ = previous/next, T = today, D/W/M = day/week/month, 1/2/3 = calendar/list/tiles, S = sidebar, R = refresh, / = search, O = oshi-only, Esc = close (disabled while a text field is focused).
• Faint arrow buttons (‹ ›) appear at the left and right edges of the calendar, like turning pages in an e-book reader. Clicking them moves back and forth just like the "←" "→" buttons at the top.
• The Month × Calendar view has two panes: a month grid 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 (each member appears once; the ring color shows their most important status). Click a date or "+N" to switch the list on the right, and use "Open day view →" to jump to that day's Day view. Clicking an icon directly opens the detail window.
• The sidebar's open/closed state is remembered on this device and restored next time.

Using on smartphones and tablets

Content specific to narrow, touch-operated devices such as smartphones.

• We recommend the List or Tile view.When many streams overlap, the "Calendar" block layout gets cramped on narrow screens; fixed-height rows or thumbnail-focused tiles in chronological order are easier to scan.
• Swipe the calendar left or right to move back and forth (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 at its left or right edge.
• In the Month × Calendar view, each day shows its number of events(in red if something is live), plus a 🎂 on days with anniversaries. Tap a date to open that day's schedule below it. Press "Open day view →" to jump to that day in the Day view.
• To make the most of the screen, the sidebar always starts closed. Press "Show sidebar" in the header to change member filters and other settings.
• Automatic refresh may pause while the browser tab is in the background, but when you come back, the page updates automatically if enough time has passed since the last refresh.
