It's hard to tell exactly from your screenshot as a lot of the variables have been named "day/night" which makes it slightly harder to troubleshoot. Is it actually the Day variable changing back to 1 or is it just what's being said in the HUD since you added the new variables? It could just be an issue with what's being displayed.
Viewing post in Calendar days displaying not right
It's all copied from your day/night demo I didn't change anything. I'm sure the problem with day coming back to 1 is because calendar event, because it happend only on the map with this event.
I found another problem. When you check the calendar and then close it, the date changes to the one where the mouse cursor was last time. So let's say I'm starting the game 1 day Spring, then open the calendar, push the next button it will change to 1 day summer, then when I press exit the date stays on 1 day summer on the map. It should just come back to the actual game in the date but it's not.
Yes make sure the autorun event on the page in the demo isn't running again, or it's going to set your variables back to 1. You only need to run that event once at the start of your game.
As for the selected day, it works fine in the demo files so that might also be an issue with the variables changing it back to 1?
Okay I sort the days counting error out. Now what do you think is wrong with the seasons. When I open the calendar and click on it at any season it change the season in game to the one I clicked in the calendar (The day stay the same as before so it's fine) only season is changing . So i start at 1 spring, I click summer, bang now it stays summer in game. Is this can be problem with 0393 variable? Or calendar ui?
Also when I click next it changes in game season permanently too
