Go to Settings > Calendar > Accounts and delete the calendar subscriptions that you do not recognize.


If you don't see any subscription or suspicious account:


  • Open the Calendar app.
  • At the bottom of the screen, tap Calendars.
  • Look for a calendar that you do not recognize. Tap the More Information button “i" next to this calendar, then scroll down and tap Delete Calendar.
