Working Days Calculator

Count Mon–Fri working days between two dates, with optional holidays.

Tool workspace

Inclusive Mon–Fri count; listed holidays are excluded.

Weekends are Saturday and Sunday. Optional holidays are YYYY-MM-DD, one per line. Dates are processed locally in your browser.

How it works

Enter start and end dates. The tool counts inclusive Monday–Friday dates and excludes optional holidays (YYYY-MM-DD, one per line).

Weekend definition: Saturday and Sunday. Timezone: calendar dates in your browser; DST does not invent phantom days.

Empty incomplete inputs clear the result—no error.

Examples

  • Mon–Fri same week with no holidays = 5 working days
  • A holiday on Wednesday reduces that week to 4
