How the working days in December 2028 are counted
One federal holiday falls in December 2028: Christmas Day on Monday 25 December 2028. It takes one weekday out of the count, leaving 20 working days from 21 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 20 as the federal baseline for December 2028 and adjust it for your own calendar.
December 2028 next to the months around it
December 2028 has 20 working days, the same as November 2028. A 31-day month has 21, 22 or 23 weekdays depending on the day it starts on; a Friday start gives this one 21, and the holiday count settles the final figure.
December is the third month of the fourth quarter. Q4 2028 has 61 working days in total: October 21, November 20 and December 20. That is 488 working hours for the quarter at 8 hours a day, out of 2,000 for the whole of 2028.
