[REQUEST] Seasonal Suns

[branch?]

In very north and very south places on Earth there are seasons of forever day and seasons of forever night. On ice sheets I'd love it if during Winter and Fall the sun doesn't show up at all and during Summer and Spring the sun doesn't go down. I don't know how to mod so I'm asking for someone with more expertise to create it.
