How the working days in May 2028 are counted
One federal holiday falls in May 2028: Memorial Day on Monday 29 May 2028. It takes one weekday out of the count, leaving 22 working days from 23 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 22 as the federal baseline for May 2028 and adjust it for your own calendar.
May 2028 next to the months around it
May 2028 has 22 working days, two days more than April 2028 (20) and one day more than June 2028 (21). A 31-day month has 21, 22 or 23 weekdays depending on the day it starts on, and a Monday start gives this one the full 23, and the holiday count settles the final figure.
May is the second month of the second quarter. Q2 2028 has 63 working days in total: April 20, May 22 and June 21. That is 504 working hours for the quarter at 8 hours a day, out of 2,000 for the whole of 2028.
