How to delete calendar event? Iphone?

I have loads I calendar event I don't want and when I try to delete the event they keep popping up, how do I properly delete them?

Click on the event
click edit in upper right corner
scroll down to bottom of the screed and delete event

If you have email set up on your iPhone, there's a possible chance that the calendar events are still filtering in from your email, since they save backups of calendar events through email. Try deleting all calendar events from your email. If this also fails, try emailing Apple Support or posting a question on the Apple forum. Best of wishes.

Tap on the event then tap on edit then stroll all the way to the bottom and tap delete event
