Enter a start and end date. Choose whether to include weekends in the count, and enter how many public holidays fall within the range to subtract them. The calculator returns the working days, the number of weekend days and the total calendar days.

Total days

A working days calculator counts the business days between two dates — excluding weekends and any public holidays you specify — alongside the weekend count and total calendar span. Ideal for project timelines, SLAs and delivery estimates.

How it works

  • Total days = calendar days between the dates
  • Weekend days = Saturdays and Sundays in range
  • Working days = total − weekend days (− holidays when selected)

Enter your own holiday count because public holidays vary by country and region.

Examples

  • 1–31 Jan 2026 (no weekends, 1 holiday) = 21 working days
  • Include weekends to get the full calendar count
  • Subtract the number of public holidays that fall on weekdays

Frequently asked questions

Are the start and end days counted?

Both the start and end dates are counted as inclusive, so a Monday-to-Friday span is 5 working days.

Which holidays are used?

None automatically — public holidays differ by country. Enter how many fall within your range (on weekdays) and they'll be subtracted from the working-day count.

Just for the giggles, much love.
