Humans on earth use “years” based on your world going around your sun. Since you have seasons that go in a cycle following that, it’s easy to keep track of. We have a scientific word that means “one rotation around our sun,” but it’s barely ever used. The word that’s much more commonly used translates literally as “great week.”
A great week is 25 weeks, or 625 days. It’s a nice even number, whereas one orbit around our sun is just a smidge under 80 days. That wouldn’t fit nicely into calendars, and every once is a while that little fraction of a day that’s missing would have to be accounted for. overall, the system just wouldn’t make much sense. Obviously we’re not tidally locked, or we wouldn’t have days at all.
Also, its worth noting that it turns out we do have very weak “seasons” here. I looked this up in the library, and apparently there is enough of a tilt in our axis that it had to be accounted for when we started doing work on artificial satellites and in weather forecasting.
Your questions really force me to do some research sometimes! I feel like I’m getting smarter spending so much time reading for them!
