About this tool
This calculator steps through every day from the start date to the end date and counts only Mondays to Fridays. It is handy for deadlines, leave planning and project timelines. Very long ranges over 10 years are rejected so the count stays fast and meaningful.
Frequently asked questions
Are public holidays excluded?
No. Only Saturdays and Sundays are skipped; public holidays vary by country, so add those yourself if you need them excluded.
Are both the start and end dates counted?
Yes, if the start or end date falls on a weekday it is included in the count.
