Easter is on my calendar.is there a reason Easter is not on calendar but Christmas, indigenous people day on it etc.
Try the following:
Tap this link on your iPhone:
webcal://files.apple.com/calendars/US32Holidays.ics
If it doesn’t open a new tab, copy the link and paste it to a new tab. You’ll be asked to open the link in Calendar. Open it there, then subscribe to the calendar.
This will add US holidays to your calendar, and Easter is among them.
Obviously the missing Easter Sunday is a bug or feature of the US built in calendar.
