Calculates the month difference between two dates.

• Subtract start from end and use datetime.timedelta.days to get the day difference.
• Divide by 30 and use math.ceil() to get the difference in months (rounded up).

from math import ceil

def months_diff(start, end):
  return ceil((end - start).days / 30)

from datetime import date

months_diff(date(2020, 10, 28), date(2020, 11, 25)) # 1
