How it works

Count working days between two dates using configurable weekends and published holidays.

  1. Enter the start and end dates.
  2. Choose the country and its weekend pattern.
  3. Optionally exclude published holidays, then calculate working and non-working days.

Example

A Monday-to-Friday workweek can exclude Saturday, Sunday and verified national holidays from a delivery estimate.

How accuracy is handled

Holiday results use verified records available for the selected country and year; official calendars remain authoritative.

Privacy: Inputs are validated and calculations use calendar-aware IANA time-zone rules.

Frequently asked questions

Can weekends be changed?
