  • Labor Day — observed September 7, 2026

How this number was reached

Every calendar day in September 2026 is checked in turn. Saturdays and Sundays are removed, leaving 22 working days out of 30 calendar days. The 11 US federal holidays are then matched against those weekdays using their observed dates — a holiday falling on a Saturday is observed on the Friday before, and one falling on a Sunday on the Monday after — which removes 1 more day.
