The Calendar tool

Calendar: today and tomorrow at a glance in the notch

What's next today, and what's first tomorrow, one hover away.

Calendar reads the calendars on your Mac (iCloud, Google or any account you've added to Calendar) and shows today and tomorrow.

Questions, answered.

Can I add events?

No. Calendar is read-only on purpose.

Which calendars does it show?

The ones in the Calendar app on your Mac. macOS asks for permission the first time.
