How Many Working Days Are in a Month?
Payroll, project plans and leave calculations all run on working days — but a month doesn't have a fixed number of them. Here's how many working days are in a month, and how to count any month exactly.
The quick answer
A typical month has 20 to 23 working days (Monday–Friday), before public holidays. The exact number depends on how many weekends fall in the month and which weekday the 1st lands on. February is usually the lowest; months that start on a Monday tend to have the most.
Count any month exactly
Rather than counting on a calendar, use the business days calculator — enter the first and last day of the month and it returns the exact number of Monday-to-Friday days, and how many weekend days were skipped.
Why it matters
Daily-rate pay, freelancer invoicing, SLA deadlines and capacity planning all depend on the real working-day count, not "about 22". Using the wrong number throws off budgets and timelines.
Don't forget holidays
The business-day count excludes weekends but not public holidays, which vary by country and state. Subtract your local holidays from the result for the true figure.
