Frequently asked

Which holidays are counted?

The 11 US federal holidays: New Year's Day, MLK Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas Day.

What is an "observed" day?

If a fixed-date federal holiday (Jan 1, Jul 4, Nov 11, Dec 25, or Juneteenth) falls on Saturday, the federal government observes it on the Friday before. If it falls on Sunday, it's observed on the Monday after. This tool follows that convention.

Can I add company or regional holidays?

Yes — paste them as YYYY-MM-DD, one per line or comma-separated. They're treated as additional holidays and won't double-count if they overlap a weekend or federal holiday.
