Christmas Day closes USPS, UPS and FedEx on Friday, December 25, 2026, so yes, it delays mail by one business day. The bigger slowdown, though, comes from the record volume in the days before it. Anyone asking does Christmas delay mail is usually feeling both at once.
USPS delivers normally on Saturday, December 26, so many delayed letters and packages land the very next day. Others slip to Monday, December 28, once Sunday is counted out.
Christmas week, carrier by carrier
Each carrier treats the three days around the holiday a little differently. The table shows the 2026 pattern.
| Carrier | Thursday, Dec 24 | Friday, Dec 25 | Saturday, Dec 26 |
|---|---|---|---|
| USPS | Normal routes, very heavy volume | Closed; Priority Mail Express only, select markets, for a fee | Normal Saturday delivery |
| UPS | Deliveries run normally; Air pickups only if prearranged; no Ground pickups | Closed | Not a full delivery day; Saturday Air only if the shipper paid |
| FedEx | Modified Service | Closed; Custom Critical only | Pickup, sorting and delivery resume |
Christmas Eve is not a postal holiday. USPS carriers run their normal routes on December 24, just with far more packages than usual.
Does Christmas delay mail from UPS and FedEx?
Yes, and for UPS Ground the pause can run longer than for USPS. UPS takes no Ground pickups on December 24 and closes on December 25. Its Saturday is not a full delivery day, so many Ground packages handed over on Christmas Eve start moving on Monday, December 28.
FedEx closes on December 25 except for its Custom Critical service. It restarts pickup, sorting and delivery on Saturday, December 26, so FedEx packages usually lose just the one day.
The gap after Christmas is short. Returns and gift exchanges then fill the networks again in the week before New Year’s Day.
How much later will your mail arrive?
By USPS rules, one business day. Business days exclude Sundays and federal holidays, so Christmas simply drops out of every estimate that crosses it.
Here is how that looks in practice. A Ground Advantage package with a 2 to 5 business day window ships on Monday, December 21, 2026. Its last expected day would have been Saturday, December 26.
With Christmas removed and Sunday skipped, that last day becomes Monday, December 28. The package still counts as on time, even though it missed the holiday.
Why Christmas delays run longer than one day
The two weeks before Christmas are the busiest of the year for every carrier. Sorting plants and delivery routes run near capacity. Small slips of a day or more are common even before the holiday arrives.
Collection boxes add their own gap. A card dropped in a blue box after the last pickup on December 24 does not move until Saturday. With the Sunday after it, some local cards take until Monday to arrive.
That is why the published cutoffs sit a week early. For delivery by December 25 in the lower 48 states, USPS recommends mailing by December 17 for Ground Advantage and First-Class Mail, December 18 for Priority Mail, and December 19 for Priority Mail Express. Our page on USPS Christmas shipping deadlines has the full list.
What your tracking shows over Christmas
Expect frozen tracking on December 25 across all three carriers. A package often holds its December 24 scan until Saturday or Monday, then moves quickly.
An Out for Delivery scan on Christmas Eve that never turns into a delivery is common at peak. The item usually goes back on the truck on the next delivery day. For USPS that is Saturday; for UPS Ground it is often Monday.
If tracking still has not moved by the middle of the following week, our guide to what to do when USPS tracking freezes walks through the next steps.
When a late package is normal and when to worry
Most people asking does Christmas delay mail have a gift that missed the big day. Use the adjusted window and allow for peak volume.
- Normal: a USPS package due on December 25 arrives on Saturday, December 26 or Monday, December 28.
- Normal at peak: one extra day beyond the adjusted estimate in the week before Christmas.
- Worth checking: no new scan by the end of Tuesday, December 29.
- Time to act: more than two business days past the adjusted estimate. For USPS, file a Missing Mail search, which opens 7 days after mailing.
To see a fair window for your route, estimate the transit time for your ZIP codes and leave Christmas out of the count.
Christmas 2027 falls on a Saturday
Christmas Day 2027 is a Saturday. Under the federal rule, a Saturday holiday is observed on the Friday before it, which is Friday, December 24, 2027.
USPS has not published its own 2027 holiday list yet. Expect the post office closure to follow the federal date, but check the official schedule before you plan around Saturday, December 25, 2027.
How to keep Christmas from slowing your mail
- Mail cards by the middle of December, well ahead of the recommended dates.
- Use the counter instead of a collection box in the last few days, so each item gets an acceptance scan.
- Upgrade to Priority Mail or Priority Mail Express for late gifts rather than hoping Ground Advantage beats the rush.
- For a delivery on December 25 itself, Priority Mail Express offers holiday delivery in many major markets for an added fee.
USPS explains that option on its Priority Mail Express page. Confirm the destination is covered before you pay for it.
The bottom line
So, does Christmas delay mail? By one business day on paper, and often by more in practice, because the holiday sits at the peak of the year. USPS catches up on Saturday, December 26, while UPS Ground usually resumes in earnest on Monday.
