Holiday Shipping Deadline Calculator
USPS said military and international holiday deadlines would be published on its holiday shipping page starting mid-October 2026 — they weren't available yet when this tool was built, so no date is guessed here. Check usps.com/holiday/holiday-shipping-dates.htm closer to that date.

Frequently asked questions
Where do these dates come from?
USPS's official 2026 holiday shipping announcement (about.usps.com), recommended for delivery by December 25. These are USPS's own recommended dates, not a third-party guess.
Why do Alaska/Hawaii/Puerto Rico/territories have a different date for Ground Advantage?
USPS's 2026 schedule lists Ground Advantage one day earlier (Dec 16 vs Dec 17) for these destinations, reflecting longer transit times. First-Class, Priority, and Priority Express deadlines are the same as the contiguous US.
What about military (APO/FPO/DPO) or international addresses?
USPS said complete military and international dates would be published on its holiday shipping page starting mid-October 2026 -- they weren't available yet when this tool was built, so we don't guess at them. Check usps.com/holiday/holiday-shipping-dates.htm directly closer to that date.
