USPS Holidays 2026: Closures, Delivery Changes, and Last Ship Dates

USPS observes 11 federal holidays in 2026. On each of these dates: post office lobbies are closed, no carrier delivery happens, and pickup services stop. Priority Mail Express is the one exception — it delivers on most holidays, including Thanksgiving and Memorial Day, because the money-back guarantee requires it.

If a holiday falls on a Saturday, USPS observes the closure on the preceding Friday. If it falls on a Sunday, the closure moves to the following Monday. July 4, 2026 falls on a Saturday, so July 3 (Friday) is the observed closure day.

2026 USPS Holiday Schedule

PME = Priority Mail Express. Delivers on all holidays except Christmas and New Year’s Day.

Last Ship Dates to Hit the Next Business Day

If you need a package to arrive before a holiday (gifts, business documents, time-sensitive items), ship before these cutoffs:

Christmas (December 25, Friday):

• Priority Mail Express: Ship by December 24 for Dec 24 delivery — PME does not deliver on Christmas Day itself
• Priority Mail: Ship by December 22 (Monday) to expect Dec 24 arrival
• USPS Ground Advantage: Ship by December 17-18 — ground service crosses the weekend; volume and routing delays are common in the final week
• Media Mail: Ship by December 10 at the latest — this is the lowest-priority class and frequently gets delayed through December

Thanksgiving (November 26, Thursday):

• PME delivers on Thanksgiving, so any shipment sent with PME by November 25 should arrive on November 26
• For everything else: ship by November 24 to arrive before Thanksgiving, or accept delivery on November 28 (Friday after Thanksgiving is a standard business day)

Other federal holidays:

• Standard rule: ship 2 business days before a 1-day closure to ensure a Priority Mail shipment lands the day before the holiday, or the next business day after it

What Closes on USPS Holidays

Mail and packages continue moving through USPS distribution facilities on holidays — what stops is the last-mile carrier delivery and counter service. A package in transit on a holiday will be processed normally at distribution centers; it just won’t go out for delivery until the next business day.

Days That Are NOT USPS Holidays

Several days cause confusion because of retail significance:

Black Friday (November 27, 2026): Not a federal holiday. USPS delivers and post offices are open. Volume is high but service is normal.

Christmas Eve (December 24): Not a federal holiday. Post offices are open on December 24 (Christmas Eve) with regular hours. Full carrier delivery runs. Significant volume, so expect your carrier later in the day than usual.

New Year’s Eve (December 31): Not a holiday. Full delivery day with regular post office hours.

Easter, Halloween, Valentine’s Day, Mothers’ Day: None of these are federal holidays. USPS delivers and post offices operate normally.

Priority Mail Express on Holidays: What the Guarantee Covers

PME delivers on all federal holidays except New Year’s Day and Christmas Day. The money-back guarantee still applies on holiday deliveries — if USPS commits to a holiday delivery date and misses it, you can claim a refund.

For holiday PME shipments, drop-off cutoffs shift earlier. On the day before a holiday, many post offices move their PME acceptance cutoff up by 1–2 hours. Check the USPS Service Commitments tool with your origin ZIP to confirm your specific cutoff.

If you are trying to sanity-check whether the holiday affects transit speed or only the final route, USPS delivery hours is the more useful companion page.

Original Data: Impact Analysis of Holiday Closures on Ground Advantage

We cross-referenced 2026 holiday dates against typical USPS Ground Advantage routing patterns to identify the highest-risk shipping windows:

Highest-risk ground windows in 2026:

1. Christmas week (Dec 21–24): Ground Advantage shipments sent after December 17 face elevated delay risk. Volume peaks, facility capacity is strained, and the Dec 25 closure removes one business day from cross-country routing.

2. Thanksgiving week (Nov 23–26): 3-day holiday weekend effectively removes 1–1.5 days from Ground Advantage transit. Cross-country shipments sent after Nov 19 risk missing the Thanksgiving window.

3. July 4th (July 3 closure + weekend): July 4 falls on a Saturday in 2026; the observed closure is July 3 (Friday). This creates a 3-day gap (Fri–Sun) for ground service. Shipments needing delivery before July 4th should leave by June 30.

Safest strategy for all these windows: Use USPS Ground Advantage only for shipments where the extra 1-2 business days won’t matter. For anything time-critical, step up to Priority Mail or Priority Mail Express.

If your concern is not the holiday itself but the late-day route window around it, when USPS stops delivering is the page that answers that better.
