" Use Siri Suggestions in Calendar on Mac

When Siri recognizes events in apps such as Mail, it adds them to your Siri Suggestions calendar. You can delete events from the Siri Suggestions calendar, or confirm an event by moving it to one of your other calendars. You can also turn the Siri Suggestions calendar on or off.

Turn the Siri Suggestions calendar on or off

1. On your Mac, choose Apple menu  > System Settings, then click Siri & Spotlight  in the sidebar. (You may need to scroll down.)
2. Click the Siri Suggestions & Privacy button, then choose Calendar in the list on the left.
3. Turn Show Siri Suggestions in App on or off.
4. Click Done.

When you turn off the Siri Suggestions calendar, any unconfirmed event suggestions are deleted and the Siri Suggestions calendar is hidden."
