I'm trying to put together a spreadsheet to track dates for things like planting and such in Don't starve. However, I've noticed over a lot of games that it seems like the seasons aren't totally invariable in duration. I watch a lot of streams too, and since i started my calendar project, i notice some variation there too.
Is this just sloppy observation on my part, or is there some variation sometimes? Does winter always start on the same day? Is a full "year" always 36 days long?
I looked in the wiki but it didn't mention anything like this.
Thanks in advance!
