How the working days in December 2026 are counted
One federal holiday falls in December 2026: Christmas Day on Friday 25 December 2026. It takes one weekday out of the count, leaving 22 working days from 23 weekdays.
The rule is the same on every page here: count Monday to Friday, then take off any federal holiday that lands on one of those days. The holiday dates are the ones the US Office of Personnel Management publishes for federal pay and leave. State holidays, religious holidays and company closures are not included, and other countries have different lists entirely, so treat 22 as the federal baseline for December 2026 and adjust it for your own calendar.
December 2026 next to the months around it
December 2026 has 22 working days, three days more than November 2026 (19) and three days more than January 2027 (19). A 31-day month has 21, 22 or 23 weekdays depending on the day it starts on, and a Tuesday start gives this one the full 23, and the holiday count settles the final figure.
December is the third month of the fourth quarter. Q4 2026 has 62 working days in total: October 21, November 19 and December 22. That is 496 working hours for the quarter at 8 hours a day, out of 2,000 for the whole of 2026.
