How the working days in January 2027 are counted
Two federal holidays fall in January 2027: New Year's Day on Friday 1 January 2027 and Birthday of Martin Luther King, Jr. on Monday 18 January 2027. Together they take two weekdays out of the count, leaving 19 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 19 as the federal baseline for January 2027 and adjust it for your own calendar.
January 2027 next to the months around it
January 2027 has 19 working days, three days fewer than December 2026 (22) and the same as February 2027. 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.
January is the first month of the first quarter. Q1 2027 has 61 working days in total: January 19, February 19 and March 23. That is 488 working hours for the quarter at 8 hours a day, out of 1,992 for the whole of 2027.
