Im not sure if its just me but in both windows and android downloads i start wit month 3 day 1 is it really the start date? also unfortunately because of it i cant access the new content as i always go on the max limit you can go in months where you can save and beacause of the fact that i cant save beyong month 7 oe 8? i dont remember im too afraid to proceed without saving
The game does indeed start on 3/1 (it's the date, not the amount of days since the start of the game)
Your current save files will be just fine if you choose to play past the date limit. The option's just there so you can explore the rest of the game without breaking events that are going to be added to future dates.
