How the working days in January 2028 are counted
One federal holiday falls in January 2028: Birthday of Martin Luther King, Jr. on Monday 17 January 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 January 2028 and adjust it for your own calendar.
January 2028 next to the months around it
January 2028 has 20 working days, one day fewer than December 2027 (21) and the same as February 2028. A 31-day month has 21, 22 or 23 weekdays depending on the day it starts on; a Saturday start gives this one 21, and the holiday count settles the final figure.
January is the first month of the first quarter. Q1 2028 has 63 working days in total: January 20, February 20 and March 23. That is 504 working hours for the quarter at 8 hours a day, out of 2,000 for the whole of 2028.
