Seasons callendar whoopsie

Yes, it does make a bit of a 'holiday' mess when you switch from a longer to shorter season (hence the warning they give in the game when you do it). When this happened to me I was very frustrated until I started to edit them manually in the calendar. There's an up-side. You will have the opportunity not only re-make holidays but you will also be able to make your own, remove ones you find annoying, alter the requirements, etc. I was actually much happier with the results of my 'overhaul' so hopefully you will be as well.
If you're unable to reproduce the exact holidays and 'dates' they fall on in your game or find a list of these online you could try beginning a new/fresh game at the season length you want and go in and check where the holidays fall in it, copy their names and requirements, etc., and re-produce these manually in your current game.
I found a couple of links that may prove helpful for you:

Hope this helps. Let us know how it goes.
