Anyone else have random reminders that make no sense?

Bought a new iPad as my old one died in 2015 and I've only just got round to replacing it.
After setting it up, I went into the calendar to set up reminders of some events and noticed that, at some point, I had set up a random reminder that simply said "work". There was no regularity to it, which has thrown me because every job I've had has had regular working patterns (for example one weekend in every 4). This was the odd Saturday every one or 2 months. It was also just for a single hour which also makes no sense as, if it was for work, I'd have put my full hours if I needed to set a reminder.
I have no idea exactly what "work" this related to and, since I'm no longer in that job, I'll likely never know.

I've an alarm that goes off on a Wednesday at 16:10. Not a clue what it is for. No one has rang looking me. Is it for a call? Is there a conference? Am I meant to bring a child somewhere?

I've just turned it off. I give up🤣

I do this. And my alarm clock in the morning for years was callled the name of the father of a kid from my sons class. I never even met the man, just got a RSVP text from him once about my sons party. His name is VERY unique so I know it was definitely his name.
