Work Days Calculator
Calculate the number of business days (weekdays) between two dates, excluding weekends. Great for project planning and deadline tracking.
How It Works
Select a start date and an end date. The calculator counts each day between them (inclusive) and categorizes it as either a business day (Mon–Fri) or a weekend day (Sat–Sun).
- Business days — weekdays (Monday through Friday)
- Weekend days — Saturdays and Sundays
- Total calendar days — all days including weekends
- Full weeks — complete 7-day weeks in the range
The date order doesn't matter — the calculator always uses the earlier date as the start.
Frequently Asked Questions
What counts as a business day?
Business days are Monday through Friday. The calculator excludes Saturdays and Sundays from the count. Note that public holidays are not excluded as they vary by country and region.
Does this include the start and end dates?
Yes, both the start and end dates are included in the count. If the start date is a Monday and the end date is a Friday of the same week, the result will be 5 business days.
Are public holidays excluded?
No, this calculator only excludes weekends (Saturday and Sunday). Public holidays vary by country, state, and organization, so they are not automatically excluded. You can manually adjust the result if needed.
