One calendar for all of them

Connect several Google and Microsoft accounts next to your Mac’s own calendars, then choose exactly which calendars appear.

Edit it where it lives

Change a time, a title or an alert and it goes back to the calendar it came from. Nothing is copied between your accounts.

Offline, then in sync.

Every change is saved on your Mac first and sent when you’re back online. If someone changed the same event meanwhile, TotalCalendar shows you both versions and you choose.

Try it: turn the Wi-Fi off, then back on.

Private by design.

There’s no TotalCalendar account. The app talks to Google, Microsoft and Apple directly, keeps your sign-ins in the macOS Keychain, and stores your calendar on your Mac.
