I’d like to change the calendar (I’m on a Raspberry Pi 3B) by moving to a different month. Just like you do on a wall calendar, flip to a different month. I realize I’ll need to add some type of code or button connected
to GPIO pins and code it to do what I want. I just need to know, typically, where do the calendar modules (I know they’re somewhat different) get the starting date to display the month so
that when I push a button it will change the month and move forward a month (or back a month if I have 2 buttons). Any help would be appreciated.
