hey there @zarte13, welcome to the discourse 
i dont think this is actually a bug, as it goes from day 25 of deepmun into day 1 of dewmun, meaning that its actually going into a different month of the stonehearth calendar, and deepmun only has 25 days in its month.
but i could be wrong! so i’ll page some of the devs to make sure,
@brad, @yshan, and @sdee, how many days are there supposed to be in the month of deepmun?
25 ^^ Day25 of Deepmun and Day 1 of Dewmun 
@8BitCrab, I think you might be mistaken here. Here is the calendar_constants.json file:
{
"ticks_per_second" : 9,
"seconds_per_minute" : 60,
"minutes_per_hour" : 60,
"hours_per_day" : 24,
"days_per_month" : 30,
"months_per_year" : 12,
"start" : {
"second" : 0,
"minute" : 0,
"hour" : 8,
"day" : 0,
"month" : 1,
"year" : 1000
},
"hour_names" : [
"Aughtaur",
"Twivaur",
"Thrisaur",
"Quarthaur",
"Fifaur",
"Sesaur",
"Sevaur",
"Ochaur",
"Neinaur",
"Tethtaur",
"Elehaur",
"Dovaur"
],
"month_names" : [
"Bittermun",
"Deepmun",
"Dewmun",
"Rainmun",
"Growmun",
"Goldmun",
"Feastmun",
"Warmun",
"Newmun",
"Azuremun",
"Hearthmun",
"Northmun"
],
"event_times" : {
"midnight" : 0,
"sunrise" : 6,
"midday" : 14,
"sunset_start" : 20,
"sunset" : 22
}
}
The relevant line is "days_per_month" : 30,, looks like each month has a constant 30 days.
That being said, @zarte13 it looks like this might be an issue with saving, let me see if I can replicate it.
Alright @zarte13, I was not able to replicate this myself. I just ran the game on 64x speed and saved each day, and I was able to see day 26 (and 27-29…):
