I use holidays a lot in my games. Part of the reason why I haven’t bought the High School expansion. My sims ages slowly so they can be teenagers for 7 to 10 weeks. Having prom taking up a day of the weekend for the family for that long is not fun at all.
I also with that we could save out holidays in some ways in the calendar even if we don’t participate with the current household.
I often make my own holidays that suit my saves. Often giving my sims one day a week extra away from work so that we have time to do other things. Also a nice way to save ideas that you would like to do in your save until later. I put up goals for myself. A holiday with a fish symbol and the text lvl 4. Then I have given my sim a challenge to get to lvl for prior to that date. When I reached the goal I delete the reminder holiday since it is no longer needed.
