Date calculator

Count calendar days and business days, or shift a date by calendar units or workdays.

Get started

  1. For a count, enter two dates and choose whether to include the later date. Enter holidays in More options.
  2. To move a date earlier, enter a negative number. Use business-day shift to skip Saturdays, Sundays and your holidays.

Good to know

The calculation runs in your browser. Use consistent units in fields with no explicit unit.

Calculation method

Business days are Monday through Friday excluding your dates. Use YYYY-MM-DD once or MM-DD every year. A business-day shift counts the earlier endpoint and excludes the later one; the result can land on a weekend or holiday. Month shifts clamp to month-end.
