How the working days in May 2027 are counted
One federal holiday falls in May 2027: Memorial Day on Monday 31 May 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 May 2027 and adjust it for your own calendar.
May 2027 next to the months around it
May 2027 has 20 working days, two days fewer than April 2027 (22) and one day fewer than June 2027 (21). 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.
May is the second month of the second quarter. Q2 2027 has 63 working days in total: April 22, May 20 and June 21. That is 504 working hours for the quarter at 8 hours a day, out of 1,992 for the whole of 2027.
