Working Days Calculator
Count business days between two dates, excluding weekends and (optionally) US or German public holidays.
Tired of doing this by hand?
Timesheet tracks your hours automatically across iOS, Android, and the web, and turns them into invoices, exports, and reports. Free plan, no credit card required.
What this calculator does
Pick a start date and an end date. The calculator counts the total days in the range, separates out weekends, and (if you pick a country) deducts public holidays. What is left is the number of working days.
Why business days matter
Project deadlines, billable estimates, and contract durations are almost always expressed in business days, not calendar days. "Two weeks" usually means 10 working days, not 14, and the difference grows fast over multi-week timelines.
Beyond a one-time count
If you regularly need to calculate working days, hours, and balances, Timesheet handles it continuously: working-time accounts, contract-aware overtime, country and state holiday calendars, and per-employee absence tracking, all in one place.
