Hell, I AM a rotational player and I don't like weekly prom. I am rotational, sure, but i play with Long lifespans, and have aging off for all but the played household (and unplayed one time per rotation) so I still experience all the days a Long lifespan brings, and they are still getting prompted to go to Prom many times during their teen years without mods. Prom should be something a teen does ONCE. I use the Calendar Tweaks mod which lets you choose when Prom happens. But there are a few potential solutions, like scaling things differently for different lifespans, (really, this should be done for many things, not just prom. I use mods in a large part so i can rebalance the game around Long lifespans, but it should be balanced differently for different lifespans by default) letting us choose when it appears, or as suggested, tying it to when the teen is set to age up. That option, yeah you may miss it if you opted to graduate early, but that would be what happens in real life too.
