 From 
https://docs.python.org/3/library/calendar.html#calendar.setfirstweekday

calendar.setfirstweekday(weekday)

     Sets the weekday (0 is Monday, 6 is Sunday) to start each week. The 
values MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, and 
SUNDAY are provided for convenience. For example, to set the first 
weekday to Sunday:

     import calendar
     calendar.setfirstweekday(calendar.SUNDAY)
