What Season and What World Will You Start With?

I'm playing in Brindleton Bay and Windenburg in my current save and rotating. I really wouldn't mind starting in any or even whatever the game defaults too because I want to see the effects of the climate in general, heat, rain, snow ect.. on the sims and the plants. I'll probably focus on my gardening families the most until I get a hang of it. Do we get to choose how long a season will last?
