How can I delete iPad calendar events when no edit button appears? Clicking on events only results in "details" button.
Tap the event, then tap the Edit button on the top right. Scroll to the bottom and tap Delete Event. If you don't have the ability to delete the event (it's a shared calendar) then the Edit button will not appear.
Go to the month calendar and double-click on the event. It does not give you the option to delete but you can decline the invite.
