How to erase all data from Calendar app

[Shah_anish0207]

My university timetable is synced with the calendar app, but because I changed modules, I got a new calendar. I tried to replace my old one with the new one, but now both have merged, so I have twice the amount in a week that I would normally have and only want the newer one. I tried to erase all data in Calendar app so I could have a fresh start but there is no option for this. What do I do?

Have they merged into same calendar or are they listed separately.

Only way I've managed to ever get rid of local calendars is to use an app to fully remove local folders but can't remember the name

Hi, You can search based on events/sender name or email id or anything that is common across events. Once the events are listed, select 1 event, then select all and then delete them.
