How this number was reached
Every calendar day in January 2027 is checked in turn. Saturdays and Sundays are removed, leaving 21 working days out of 31 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 2 more days.
