How many working days are on average in a month?
If we divide 250 days in a year by 12 months we do have 20.8 working days on average in 2025.
To calculate working days monthly, you can use the following formula:
Working days per month = (Total days per month - Weekends per month - Holidays per month)
Where:
Since the formula for weekdays = Today days - weekends, then we can simplify the formula to calculate Working days as following: Weekdays - Holidays, where weekdays = days other than Sunday or Saturday.
Note that the holidays are different from one country to another.
For example, suppose we calculate the number of working days in January 2025. In that case, we know that there are 31 calendar days, 8 weekend days, and two public holidays on January 1 and January 15: New Year's Day and Martin Luther King Jr. Day. Both days fall on Monday.
So, the overall calculation for the working days in January is 31 - 8 - 2 = 21 working days.
