Groups Manager for Google Calendar

Group your Google Calendar calendars and switch between groups instantly, even with hundreds of calendars.

Too many calendars in Google Calendar? Group them once and switch in one click. Groups Manager for Google Calendar lets you create groups of calendars (teams, projects, leagues, clients…) and show only the calendars of a group with a single click. It is built for people who manage dozens or hundreds of calendars and need speed. ★ WHAT YOU CAN DO • Show only one group: one click hides every other calendar and shows just the ones you need. • Build groups in seconds: filter your calendars as you type, select all results at once, or paste a list of names. • Save the current view as a group: turn on the calendars you want and save them with one click. • Reorder groups with drag and drop. The first nine get Alt+1…9 shortcuts. • Undo the last change at any time. • Icons and colors for every group, with a searchable emoji picker. • Available in English, Español, Português, Français, Deutsch, Italiano, 日本語 and 中文. ★ BUILT FOR MANY CALENDARS • Changes are applied in batches, so Google Calendar redraws far less and the page stays responsive even with 100+ calendars. • Only the calendars that need to change are touched. There are no fixed waits and no "hide all, then show one by one". • Calendars are recognized by their ID, so groups keep working if you rename a calendar or change the Google Calendar language. ★ PRO (one-time payment, lifetime license) • Unlimited groups (the free version includes 3) • Show several groups at once (for example Football + Basketball) • Automatic rules: add every calendar whose name contains a word, exclude others with "-word"; new matching calendars join automatically • Ctrl+K quick palette inside Google Calendar • Import groups from JSON or CSV Pay once and use it on up to 3 devices. No subscription. ★ PRIVACY FIRST • Your calendars and groups are stored only in your browser. • No access to your Google account, no Google APIs, no tracking, no ads. • Only the PRO license key is validated with our payment provider (Lemon Squeezy). ★ HOW TO USE Open Google Calendar. Click the extension icon → Edit groups → Refresh calendars. Create a group, select its calendars and click it to show only that group. Works in Chrome, Brave, Edge and other Chromium browsers.
