"Bells" being added to random days

Kelsey • Mom to two beautiful girls, Mary and Rebekah.
On my calendar (when I swipe down at the home screen) the app has added "bells" to a bunch of random Tuesdays. I don't have any appointments or reminders at all and when I am on the days, it doesn't say what they are for. I want to know what they are for and/or get rid of them.
