It depends on my save... usually I garden a lot so I like to set them for 14 days so I can actually get a good seasonal garden going. But with normal aging it feels weird for a Sim to spend an entire period of their life in only one or two seasons, so I do like 7-days. I have actually just used MCCC to change their age range (just made Adult and YA each 10 days longer- we need more time to be young and hot haha!), so I will probably keep it to 14 days. Winter is kind of a bummer but that's ok, it's like that in real life too.
