The US Postal Service observes 11 holidays in 2027. On each one, post office counters are closed and regular mail is not delivered. Two of them, Juneteenth and Christmas, fall on a Saturday, and USPS keeps post offices open with normal delivery on the Fridays before: Friday, June 18 and Friday, December 24.

Why the post office is open when federal offices are closed
For office-based federal employees, a Saturday holiday becomes a Friday day off. Mail carriers work Saturdays, so for USPS the Saturday is a real working day lost, and that is the day it treats as the holiday for operations. The Postal Service notes that for some of its employees the preceding Friday still counts as the holiday for pay and leave purposes, but the retail and delivery network runs.
The practical upshot for 2027: on June 18 and December 24 you can mail a package while the Social Security office next door is closed, and on June 19 and December 25 there is no regular Saturday delivery.
What still moves on a postal holiday
- Priority Mail Express is delivered 365 days a year in most locations.
- Self-service kiosks and PO Box lobbies remain accessible where the building is open.
- Mail is not collected from blue boxes, and nothing is postmarked, on the holiday.
- Private carriers set their own schedules. UPS and FedEx operate on several days when USPS is closed, such as Columbus Day and Veterans Day; check the carrier directly.
Deadlines and postmarks
If a filing or payment deadline falls on a legal holiday, many federal deadlines, including tax deadlines, roll to the next business day. A postmark cannot be obtained on a postal holiday, so anything that must be postmarked by a date should go to the counter a day early. In 2027 the Friday openings help: December 24 is a working postal day even though it is the federal Christmas observance.
Days people ask about that are not postal holidays
USPS delivers on Good Friday (March 26), on the day after Thanksgiving (November 26), on Christmas Eve and on New Year’s Eve. It does not observe Easter Monday, Election Day or any state holiday. For the bank calendar on those same days, see bank holidays.
