Calendar Checkoff – Mark Events Complete

Description

Check off Google Calendar events with Alt-click (Option-click on Mac). Repeat to remove the checkmark. Mark Google Calendar events complete without leaving your calendar. Hold Option on a Mac or Alt on Windows and ChromeOS, then click an event you can edit. Calendar Checkoff adds a ✅ to the beginning of its title. Repeat the gesture to remove it. If you plan your day in time blocks, the checkmarks show which ones you’ve finished. You stay in Google Calendar, without a popup or a separate task list. The extension runs in your browser. Google Calendar saves the title change as if you’d edited it yourself. You don’t need an account or Calendar API access. The extension has no backend, advertising, analytics, or data collection. The information used to decide when to ask for a review stays in your browser. You need permission to edit the event. Calendar Checkoff cannot change events on read-only calendars. I built Calendar Checkoff for myself and am sharing it in case you work the same way. Calendar Checkoff is an independent extension and is not affiliated with or endorsed by Google.
