How the working days in October 2027 are counted
One federal holiday falls in October 2027: Columbus Day on Monday 11 October 2027. 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 October 2027 and adjust it for your own calendar.
October 2027 next to the months around it
October 2027 has 20 working days, one day fewer than September 2027 (21) and the same as November 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.
October is the first month of the fourth quarter. Q4 2027 has 61 working days in total: October 20, November 20 and December 21. That is 488 working hours for the quarter at 8 hours a day, out of 1,992 for the whole of 2027.
