Why have I got a preset calendar event in my new Samsung Galaxy S9 phone?

[Android Central Question]

I received a new Samsung Galaxy S9 and have realized there is a preset calendar date titled Amans anniversary 7 sept, and there is no option whatsoever to delete it has anyone else had a similar issue, phone was sealed in box when received so no idea how it is on there, and its really bugging me

Welcome to Android Central! Do you know anyone named Aman? Is it definitely an anniversary or could it be a birthday?

Is it in your Google calendar at Google Calendar? That's the one the calendar in the phone syncs to. (And if that one is synced to anyone else's calendar [lower left on the calendar page] things on their calendars will show too, just as they do on yours.)
