Calendar does not refresh when deleting contacts

Question

When I delete a contact, its birthday continues to stay on the default Calendar app, in the Birthdays calendar. (FYI, this calendar automatically gathers events from contacts' dates.)



How to update/refresh the Calendar in this case?



I went to the app settings and clicked on Clear Cache, with no result. Should I do a Clear Data too?

Answer

I managed to do what I want via a combination of:




  • removing the Birthday calendar from the web account

  • removing the Birthday calendar from the calendar app

  • doing a Clear Cache and Clear Data on the calendar app

  • forcing a sync of my Google account on the phone
