Adjusting seasons length

I've been running 7 days per season from the release, but lately I see that I often wish I had more days with some of my families before rushing off. I play 50 households rotationally, and I check on half of them during a full sim year (28 days). It hardly allows for 1 day in each house. So, I think I should try 14 days per season instead.

Question is, is there anything I should be aware of before adjusting settings? I know holidays will be messed with, so I will take notes and rearrange them accordingly. I also think nature will take a few days longer to switch between seasons, which is great. But there is probably lots of stuff that will get affected?
