What combinations of lifespan/season lengh do you use?

I play on normal lifespan with 4 weeks per season, because I prioritize experiencing every season over realism. Also I play rotationally, one family per week, so I get to explore each season with four families at a time that way. It just takes a bit of planning when I am setting up for the next rotation to make sure each family gets some variety as to what seasons they are active for.
