About

This site answers one question - is the post office open today? - with a single yes or no, plus the reason and the next closure or reopening.

The answer is computed from the calendar: post office retail locations in the United States close on Sundays and on the eleven federal holidays. The federal-employee observance rule does not always predict USPS retail service: Friday, July 3, 2026 is open with normal delivery according to USPS, despite July 4 falling on Saturday. Check the official USPS holiday list for each year. The site calculates the holidays for the current and coming year in your browser, using your device's local date.

What this site is not: it does not track live, per-branch opening and closing times. Individual post offices set their own daily hours, and many run reduced hours on Saturdays or close early on days like Christmas Eve. Always confirm same-day hours with your local office before making a trip.
