Free Online Work Days Calculator

1. Pick a start date and an end date.
2. Choose a country preset, or leave it on No preset to exclude weekends only.
3. Optionally paste custom holiday dates (YYYY-MM-DD) into the custom holidays field.
4. Read the working-day count plus a breakdown of total days, weekends and excluded holidays.

Calendar days over-count when a deadline says "within 10 business days." Two weeks of calendar time is 10 working days only if no holidays fall in the middle — and most companies count differently around long weekends. A work-days calculator does the bookkeeping for you.

This tool excludes Saturdays and Sundays by default and lets you layer a 2026 public-holiday preset for the United States, United Kingdom, India or Germany. The presets cover the headline federal/national holidays (8–11 days each). You can also paste custom holiday dates as ISO strings — useful for company-specific shutdowns, regional observances or sabbaticals. Operations managers planning project deadlines, HR teams checking leave balances and contract administrators verifying SLA windows all rely on this kind of count.

The result breaks the range into total days, working days (the figure you usually want), weekend days and holidays excluded — so you can audit the count if it looks off.
