Public holiday calculator

Business Days & Public Holidays Calculator

Count working days between two dates while excluding weekends and public holidays from Nager.Date. Use it when a plain date difference is not enough because staffing, shipping, support coverage or HR planning depends on actual working days.

Date ranges can span multiple years. The browser fetches each required year for the selected country and uses local calendar dates, not UTC timestamps.

Best used for

  • Project timelinesEstimate how many working days are available between kickoff and delivery.
  • Shipping and support planningSee whether public holidays reduce weekday coverage in a selected country.
  • HR and operations checksCompare calendar time with working time before assigning shifts, onboarding dates or review windows.

Formula and method

Business days = counted calendar dates minus excluded dates. A date is excluded once if it is a weekend, a selected public holiday, or both. This prevents double-counting a holiday that falls on Saturday or Sunday.

Run the calculator to load holiday data.

Example

If a 10-day date range contains two Saturdays, two Sundays and one public holiday on a Tuesday, excluding weekends and holidays leaves 5 business days. If that public holiday falls on a Sunday, it is still only one excluded date.

Limitations

Holiday data is fetched from Nager.Date. Nager.Date focuses on public holidays and may not include school holidays, company holidays, all bank-only holidays or every local observance. Regional holidays are included only when the API returns county/subdivision data. Verify official local sources for legal, payroll, HR, contract or compliance deadlines.
