How Many Work Days in a Month

A month has 20 to 23 weekdays, and 19 to 23 work days once federal holidays come out. In 2027 the range is 19 to 23: January has 19, March has 23. Each work day is 8 hours worked; a month with a federal holiday adds 8 hours of holiday pay per holiday, so November 2027 is 160 hours worked plus 16 holiday. Banks count differently in two 2027 months, June and December, because the Federal Reserve stays open on three Fridays federal offices take off.

Work days are Monday to Friday minus federal holidays (5 U.S.C. 6103, observed dates). Hours are 8 a day: hours worked plus 8 hours of holiday pay for each weekday holiday. Banks (ACH) follow the Federal Reserve holiday schedule (Federal Reserve Board K.8). Why the 2027 year comes to 249 for federal offices and 252 for banks is on how many working days in a year.

Three 2027 Fridays: federal offices closed, banks open

Federal offices and the Federal Reserve observe the same holidays but move a Saturday holiday differently. Federal employees get the Friday before off. The Federal Reserve Banks stay open that Friday, so ACH payments and direct deposits settle as usual. A Sunday holiday moves to Monday for both.

Fri, Dec 24Christmas Day (Saturday, December 25)ClosedOpen
Fri, Dec 31New Year's Day 2028 (Saturday, January 1, 2028)ClosedOpen

That is why June 2027 has 21 work days for federal offices and 22 for banks, and December has 21 and 23. A transfer scheduled for June 18, December 24 or December 31 goes through; one scheduled for July 5 waits until Tuesday, July 6. OPM's rule: "If a holiday falls on a Saturday, for most Federal employees, the preceding Friday will be treated as a holiday for pay and leave purposes." The Federal Reserve's K.8 schedule: "For holidays falling on Saturday, Federal Reserve Banks and Branches will be open the preceding Friday," and it names June 18, December 24 and December 31, 2027. The calculator below switches between the two calendars.

Hours worked and hours paid in a holiday month

A holiday takes 8 hours off the hours worked but not off the hours paid, for anyone whose employer pays holidays. Hours paid in a month are the weekdays times 8; hours worked are the work days times 8. In 2027:

An hourly employee without holiday pay is paid for the hours worked only, so the same January is 152 hours, not 168. A salaried employee is paid the same each month whatever the count.

2027 • Federal offices • 8 hours a day. January: 21 weekdays, 19 work days; Worked: 152 hours; Holiday pay: 16 hours (New Year's Day, Martin Luther King Jr. Day); Paid: 168 hours. November: 22 weekdays, 20 work days; Worked: 160 hours; Holiday pay: 16 hours (Veterans Day, Thanksgiving); Paid: 176 hours. December: 23 weekdays, 21 work days; Worked: 168 hours; Holiday pay: 16 hours (December 24 and 31); Paid: 184 hours. No holiday pay: January: 152 hours, not 168. Hours paid = weekdays × 8. Hours worked = work days × 8.

Each month's range, 2026 to 2030

The same month changes from year to year because it starts on a different weekday and its holidays move. November never has more than 20 work days: Veterans Day and Thanksgiving are both observed on a weekday in November every year from 2026 to 2030. February is 19 or 20, and March and August reach 23. The twelve months of each year add up to the totals on how many working days in a year.
