I want to totally delete all info from the Android calendar and start over. I went into setting>app>calendar>clear data but all my entries are still there.
It sounds like your events are tied to your Google calendar. Other than unlinking or hiding your account, the only way to clear the events is to go to calendar.google.com and see if there's an easy way to reset your calendar or delete all your events one by one. Hiding or unlinking is probably easier.
