Quick answer
Monthly working day counts are useful for capacity planning, payroll checks, delivery estimates, and project reporting.
Why monthly counts matter
Two months with the same number of calendar days can have different working day counts because of weekend placement and holidays. That affects capacity, payroll, SLAs, delivery plans, and month-end close activity.
How to check a month
Set the calculator from the first day of the month to the last day of the month, choose the country, and decide whether to exclude public holidays.
Planning tip
Use the calculator for each month you need, especially around Easter, Christmas, and local public holidays where working-day counts can change quickly.
