What to Post in December: Holidays, Gifts and Year in Review

December 2026 key dates, a holiday countdown for any business, gift guides at the right time, a year-in-review that people read, and a week-by-week posting calendar.

Published on September 28, 2026 · Content creation

In December, post in three phases: GivingTuesday (December 1, 2026) and gift ideas with your shipping deadlines in the first two weeks; holiday spirit and hours around Hanukkah (December 4 to 12) and Christmas (Friday, December 25); then a year-in-review and New Year's Eve posts in the last week. An advent-style series from December 1 to 24 can tie the whole month together.

This guide covers the key dates, angles for different kinds of businesses, a ready-to-use posting calendar, and what to wrap up before mid-December. If you planned November with What to post in November, December picks up right where it left off.

What are the key dates in December 2026?

Federal holiday dates come from the U.S. Office of Personnel Management. Note that New Year's Day 2027 falls on a Friday.

How do you run a GivingTuesday post that doesn't feel like marketing?

GivingTuesday comes right after Black Friday and Cyber Monday, which makes it a good reset. Pick one cause you actually support and make the ask simple.

• A local business: introduce the food bank or shelter you work with, and say exactly what they need (volunteers, coats, donations).
• A brand with a giving program: explain how it works and share the real amount you gave last year, if you have it.
• A B2B company: a founder post about the team's volunteer day, with photos.

If you promise to donate a share of sales, spell out the amount, the dates and the recipient, and follow up with the result in January.

How do you run a holiday countdown on social media?

A countdown gives people a reason to come back. It does not need to be daily to work.

• Light version: one post a week, each with a tip, a recipe or a behind-the-scenes moment.
• Full version: 24 Stories, prepared in advance, one small useful thing per day.
• Giveaway version: if you give prizes away, publish clear official rules (eligibility, dates, how winners are picked) and follow each platform's promotion policies and your state's sweepstakes rules.

Examples: a roaster like Nord Coffee reveals one coffee origin per week; a bookstore suggests one book a day; a real estate brokerage like Casanova Immo shares one tip a week for listing in spring.

When should you post gift ideas?

Gift guides are most useful before shipping cutoffs. Post them in the first two weeks of December, and check your carrier's published holiday shipping deadlines (USPS, UPS and FedEx each post theirs), since they depend on the service you use.

1. By budget: "under $20, under $50, treat yourself."
2. By person: "for the one who has everything," "for the home cook," "for an 8-year-old."
3. By urgency: "in-store pickup until the 24th," "printable gift card."
4. By values: made locally, repairable, secondhand, if that's genuinely true.
5. For services: a session, a class or a subscription as a gift, with clear terms.

What should you post around Christmas and Hanukkah?

On the holidays themselves, most people are with family. Two kinds of posts are enough: practical information (hours, closures, last pickups) a few days before, and a short team message on the day. For restaurants and caterers, the week before carries most of the load: menus, reservations, pickup windows.

Your audience celebrates different holidays, or none. A warm, inclusive "happy holidays" works for most brands; if you post for a specific holiday, do it because it matters to your community, not as a checkbox.

How do you write a year-in-review post people actually read?

The week between Christmas and New Year's is slower, and people have a bit more time to scroll. It's the right moment for a year-in-review, as long as it's written for your audience, not as an internal report.

• Real numbers from your year (orders shipped, customers served, products launched), only ones you can back up.
• Your three standout moments, as a carousel with one photo each.
• What you learned, as a LinkedIn text post.
• Your community's favorite posts, reshared with a line of context.
• What's coming in January, to give people a reason to come back.

What posting calendar should you follow in December?

For the opening lines of these posts, borrow from our 30 hooks for November and Black Friday: several work as-is for gift guides and deadlines. If you run a café or restaurant, our one-month content plan for a café has captions you can adapt.

What should you have ready by mid-December?

1. Every countdown Story, written and scheduled in one sitting.
2. Closure and hours posts for December 24, 25 and 31, and January 1.
3. Year-in-review photos, sorted while you still have time.
4. Your first January post, so you don't restart from zero.
5. Someone on messages: even in a quiet week, order questions need an answer.

Which December mistakes should you avoid?

• Posting gift guides too late, after the last shipping deadlines.
• Forgetting your hours: it's often the most requested information of the month.
• Going all-in on promotions: December suits behind-the-scenes and thank-you posts better.
• Going quiet from December 26 to 31, when it's the right week for your recap.

A short team message is enough. Schedule it in advance, and post your hours and closures a few days before.
