To calculate the number of Sundays in a month in Excel, use the 'NETWORKDAYS.INTL' function alongside a custom weekend parameter. First, set your start and end dates for the month in question in two cells (e.g., A1 and A2). Then use the formula `=NETWORKDAYS.INTL(A1, A2, "11")-NETWORKDAYS.INTL(A1, A2)`. This formula subtracts the total days in the month from the total weekdays, based on a custom definition of 'weekend' that only includes Sunday. It effectively counts all Sundays between your start and end date.
