How this count works

Working days are the dates left after weekends and the selected holidays are removed. The federal option uses observed days off for a standard Monday-to-Friday US federal workweek.

This covers recurring federal rules for 2026 through 2031, not state holidays, one-off closures or your employer’s calendar. Changing weekends does not move the federal observed days. Check consequential deadlines with the responsible organization.

See how we count for the calendar conventions behind the answer.

Next, if you need it

If you need every calendar date instead, use days between dates.

To check a holiday rule or observed date, open the calendar sources.

A worked example

November 23 through November 30, 2026 contains 5 working days when both dates count. Thanksgiving and the weekend are left out.
