How Many Weekdays Are in 2027?

261 weekdays, 249 business days

2027 contains 261 Monday-to-Friday days and 104 weekend days. Take out the 12 US federal holidays that fall on a weekday in 2027 and 249 business days remain. That figure is the divisor behind most daily-rate, accrual and capacity calculations, and it moves between 249 and 253 depending on which weekdays 1 January and the eleven holidays land on — which is why quoting a flat "about 250" is close but not the number you want on an invoice.

Two things move that figure and neither is obvious. A holiday falling at a weekend does not cost a working day, because there was no working day there to lose — so a year where several holidays land on a Saturday or Sunday has more business days than one where they all fall midweek. And the observed-date rule can push a closure across a year boundary: when 1 January falls on a Saturday the federal observance is 31 December of the year before, so that year loses a business day and this one does not. In 2027 the count works out at 249.

If you need the working days between two specific dates rather than for a whole year, the working days between dates tool counts them and names every holiday it stepped over.
