The 2026 holiday mailing calendar has three kinds of dates: official USPS recommended send-by dates, federal holidays when mail does not move, and planning milestones that are our editorial recommendations. They are labeled separately below, because only the first two come from the Postal Service. The single most important date for most readers: mail First-Class cards and letters by Thursday, December 17, 2026 for expected delivery before December 25 — and plan to be finished well before that.
Key Takeaways
- The key official date: First-Class cards and letters by Thursday, December 17, 2026 for expected delivery before December 25 — Ground Advantage (contiguous U.S.) shares that date; Priority Mail follows December 18 and Priority Mail Express December 19.
- Alaska, Hawaii, Puerto Rico, and territory Ground Advantage carries a 10-day-or-more service expectation — mail those pieces much earlier than the printed dates suggest.
- International packages and military First-Class/Priority Mail are due December 9; military Ground Advantage was November 4.
- Hanukkah runs December 4–12, 2026 — Hanukkah cards belong in late-November mail, not the December batch.
- The editorial plan built around these dates: cards written by Thanksgiving weekend, domestic cards mailed December 1–10.

Holidays and closures on the 2026 calendar
| Date | Day | What it means for mailing |
|---|---|---|
| Thursday, November 26 | Thanksgiving Day | Post Offices closed; no mail delivery. |
| Friday, December 4 – Saturday, December 12 | Hanukkah | USPS flags that Hanukkah is earlier this year and advises adjusting mailing plans accordingly. |

A month-by-month planning calendar (editorial recommendations)
The milestones below are our recommendations, built around the official dates above. They are deliberately conservative — December mail volume runs about 40 percent above the rest of the year, according to USPS.
October
- Start or update your card and gift list.
- Choose card designs and place orders for printed cards; popular designs sell out.
- Buy stamps — Forever stamps are 82 cents, and any you already own remain valid.
November
- Early November: Confirm addresses, especially for anyone who moved this year.
- By November 4: Military packages by Ground Advantage should already be mailed (official USPS date).
- Mid-November: Begin writing cards in small batches.
- Week of November 23: Mail Hanukkah cards so they arrive during December 4–12.
- Thanksgiving weekend: A practical target for having all cards written, addressed, and stamped.
December
- December 1–10: The sweet spot for mailing domestic Christmas cards.
- By December 9: International packages and military letters/packages (official USPS dates).
- December 10–16: Mail remaining domestic cards; use Priority Mail for late packages.
- December 17: Last recommended date for First-Class Mail and Ground Advantage — a backstop, not a plan.
- December 18–19: Priority Mail and Priority Mail Express remain, at higher prices, for genuine last-minute items.
- December 21–24: If a card cannot arrive by Christmas, a New Year’s card is a graceful alternative; it needs to arrive by January 1.
January
- Send thank-you notes for gifts and hospitality during the first two weeks of January.
- Update your address list with any returned mail and new addresses from cards you received.
The December countdown, week by week (editorial)
If you prefer a weekly view, here is the same calendar compressed into the five weeks that decide the season:
| Week | Focus |
|---|---|
| Week of November 23 | Mail Hanukkah cards and international cards. Finish writing and addressing everything else. |
| Week of November 30 | Mail Alaska, Hawaii, Puerto Rico, territory, and cross-country cards. International packages out by December 9. |
| Week of December 7 | The main mailing week. Most domestic cards and Priority Mail packages should go out now. |
| Week of December 14 | Last recommended dates arrive: December 17 (First-Class/Ground Advantage), 18 (Priority), 19 (Express). Mail nothing ordinary after the 17th and expect it for Christmas. |
| Week of December 21 | Hand-deliver locally, or switch to New Year’s cards, which need to arrive by January 1. |
Reading the calendar correctly
A few details keep this calendar honest. First, “send by” means the piece should be in USPS hands before the last collection of that day — a card dropped in a collection box after its posted pickup time effectively mails the next business day. Second, the official dates assume the piece enters the mail in the contiguous United States; mail originating in Alaska, Hawaii, or the territories needs more lead time, not less. Third, Post Office retail hours and collection times vary by location during the season, and many locations extend hours on peak Saturdays; check your local Post Office’s posted hours before planning a December 17 counter trip. Finally, remember that weather is the calendar’s unlisted variable — a major storm in the second half of December can add days to any route, which is why the editorial milestones above sit a week or more ahead of the official dates.
Worked example: planning backwards from December 25
Suppose your list has three kinds of pieces: Christmas cards to family in your own state, a gift package going to a daughter in Hawaii, and Hanukkah cards for friends across the country. Read the calendar backwards and three different mailing dates fall out of it.
The Hanukkah cards are due first, even though they are “just cards.” Hanukkah runs December 4–12 in 2026, so a card mailed in mid-December arrives after the holiday ends. Working back from December 4, these cards should be in the mail during the last week of November. The Hawaii package comes next: Ground Advantage to Hawaii carries a recommended send-by date of December 16, but USPS gives those routes a service expectation of ten days or more, so the sensible target is the first week of December, not the 16th. The in-state Christmas cards are the most forgiving — First-Class Mail’s recommended date is December 17, and a December 7–10 mailing leaves a wide margin. One list, three deadlines: late November, early December, and mid-December. That spread is exactly why the month-by-month milestones above are staggered instead of clustered on a single date.
Reading this calendar from Atlanta
To see how the calendar turns into actual mailing days, take a household in Sandy Springs (ZIP 30328) with four kinds of recipients: parents in Savannah, a brother in Chicago, a sister in Seattle, and friends in Decatur marking Hanukkah. Reading the official dates backwards gives them four different mailing days:
| Pieces | Their mailing day | Why that day |
|---|---|---|
| Hanukkah cards to Decatur | Friday, November 27 | Hanukkah begins December 4; late November is on time, not early. |
| Cards to Seattle | Tuesday, December 1 | The longest domestic route on the list gets the earliest December date. |
| Cards to Chicago and Savannah | Friday, December 4 | Mid-distance and in-state cards share the first full week of December. |
| Metro Atlanta Christmas cards | Tuesday, December 8 | Local cards are the most forgiving; in our experience they arrive within days — but never treat that as guaranteed. |
The Seattle sister also gets a gift package. Ground Advantage’s recommended date for it is December 17, the same as the cards — but a package has more ways to be delayed than a card, so it leaves on December 4, with the Chicago and Savannah batch, rather than on the 17th. Packages get the conservative reading of every date on this calendar; cards get the comfortable one.
Two things are worth noticing. First, not one of these mailing days is December 17: the official backstop appears nowhere in a well-run plan, because every recipient group has its own earlier logic. Second, the earliest pieces — Hanukkah and Seattle — were identified from the calendar in November, while there was still time to write them calmly. That is the whole skill this calendar teaches: the dates are fixed, and the only real choice is whether you read them in November or discover them in mid-December.
Common calendar mistakes
- Reading “send by December 17” as “guaranteed if I mail December 17.” The dates are recommendations for expected delivery. Mail entering the system on the last recommended day has no slack for weather, a missed collection, or a missorted first pass.
- Planning international and military mail on the domestic calendar. Those tables sit weeks ahead of the lower-48 dates. If overseas pieces are on your list, their dates — not December 17 — set your real deadline.
- Forgetting Hanukkah’s early dates in 2026. December 4–12 is earlier than many senders expect; a Hanukkah card mailed with the Christmas batch on December 10 misses most of the holiday.
- Ignoring collection times. A card dropped in a box after the last posted pickup has effectively been mailed the next business day, whatever the calendar on your wall says.
- Scheduling everything for one December weekend. Printers, mail houses, and your own signing hand all have capacity limits. The calendar works when the work is spread across November and early December, not compressed into December 12–13.

Frequently Asked Questions
Can I buy stamps and prepare cards months ahead?
Yes — preparation has no deadline in either direction. Forever stamps bought in the fall mail a one-ounce letter at $0.82 whenever you use them, and cards written in November mail exactly like cards written in December. The calendar constrains only the day a piece enters the mail, so the practical move is to shift every task except the trip to the collection box as early as you like.
What if a send-by date falls on a day my Post Office is closed or I cannot get there?
Treat the previous business day as your date. The recommended dates assume the piece is accepted into the mail stream on that day; a card that sits at home on December 17 has not met the December 17 date in any sense that helps it. When a deadline matters, plan the drop-off — location, collection time, and a fallback day — not just the date.
What does “send by” actually mean — the day I drop a piece off, or the day it is collected?
The day it enters the mail stream. A piece should be in USPS hands before the last collection of the send-by date; a card dropped in a collection box after its posted pickup time effectively mails the next business day, whatever the calendar says. When a date matters, plan the drop-off — place, collection time, and a fallback day — not just the date itself.
Do these dates apply if I am mailing from Alaska, Hawaii, or a territory?
The official dates assume the piece enters the mail in the contiguous United States. Mail originating in Alaska, Hawaii, Puerto Rico, or the territories needs more lead time, not less — build in extra days beyond the printed dates, especially for Ground Advantage, which carries a service expectation of ten days or more on those routes.
