Between the first guest and the last, every holiday party raises the same quiet question about when to actually show up. Too early and the host is still wrestling the roasting pan, too late and the whole schedule slides. Etiquette expert Lizzie Post gave a specific window in a column for AARP published Nov. 6, 2026.
Post, co-president of The Emily Post Institute, wrote that guests should arrive within the first 15 to 30 minutes of a party, unless it is an open house with set start and end times. For a more formal dinner party the window narrows to the first 10 to 20 minutes. That covers the casual gathering and the formal one, and the rest of her AARP column on holiday guest manners deals with what happens once the door opens.
A 15-to-30-Minute Window and Two Exceptions
The timing rule has two built-in exceptions. An open house, where guests drift in and out between posted hours, has no arrival window at all. A formal dinner party tightens the window to 10 to 20 minutes. Post presents arrival time as one of the best practices that show consideration for hosts and help keep a guest on the invitation list. Hosts who expect a steady trickle of early arrivals may keep coffee ready, and Frenz Hub compares the Keurig K-Express and Ninja Fresh Brew for holiday guests.
The Emily Post Institute makes the same point in its Thanksgiving tips, noting that the turkey is going to be done at some point and hosts are planning around that moment. A guest who runs late, it says, should apologize and not expect anyone to have waited. Thanksgiving falls on Nov. 26 this year, the fourth Thursday of November, according to Wikipedia’s Thanksgiving entry, which leaves about two weeks to plan.
The RSVP Is Where Food Needs Come Up
Post’s first instruction is to reply promptly, whether the invitation came by mail, email or text, because a quick answer makes planning and cooking easier for the host. A yes is also the natural moment to mention allergies, food restrictions and accessibility concerns. If a guest’s needs are extensive, her advice is to offer to bring something that guest, and perhaps others, can enjoy.
That fits the Emily Post Institute’s Thanksgiving tips, which suggest an open-ended offer of help and a willingness to follow the host’s lead rather than dictating the menu.

What to Bring and What to Leave at Home
On contributions, the column is blunt: bring what was asked for. A guest assigned a side dish, beverages or hors d’oeuvres should not leave the host hanging, and it helps to confirm how many servings are needed. Arriving with more food than requested is acceptable, but Post says not to show up with items beyond what was asked for, and above all not with uninvited guests.
A hosting gift is a narrower call. Post says to bring one only for a first visit to the host’s home or when it is a popular custom in the social circle. The craftingyourhome.com piece on people who keep the same holiday traditions every year is a reminder of how much a repeat guest can already know about a household’s routine.
When Offering Help Helps and When It Does Not
Post separates the willing from the intrusive. Offering to refill drinks, refresh appetizer platters or help with setup and cleanup is thoughtful, she writes, but it belongs at casual parties where the guest knows the host very well. The more formal the occasion, the more the work belongs to the host and any helpers already lined up.
The Emily Post Institute’s Thanksgiving page takes a warmer line on the holiday itself. Because the meal is large and has a community spirit, it calls offering to pitch in a great idea for family and non-family guests alike. The two pieces agree on the underlying point, which is to read the room first. For anyone staying overnight too, Frenz Hub offers 15 etiquette tips for being the perfect houseguest, and the craftingyourhome.com list of 4 zodiac signs that tell the best stories at the family table is a light read for the dinner conversation.
Joining In, Staying Present and Pacing the Plate
Party themes and activities get a plain endorsement: ugly sweaters, a Secret Santa exchange or sharing out loud what each person is grateful for are worth joining even when they feel silly. Guests are told to stay off the phone, help themselves to the refreshments offered and chat with people they may not know. Post also advises being mindful of portion sizes relative to the number of people, since a guest can usually go back for more.
The Emily Post Institute’s guidance agrees on the phone, saying texts, scores and TikTok can wait until after the meal. It allows a moment for photos if the host offers one, then recommends putting the phone away for the rest of the meal. The institute was founded in 1946 by Emily Post, according to Wikipedia’s entry on her, and continues her work.
Good Night, Thanks at the Door and a Follow-Up Note
Leaving has its own steps. Post says to say farewell to the other guests and find the host to say thanks and goodbye before heading out. If the party is still on a guest’s mind in the days afterward, it is always a good move to write a note of thanks and send it to the host. Texts and calls work well, too, she adds, but a written note shows the host that a guest took time to reflect on the celebration.
The Emily Post Institute’s Thanksgiving tips go a step further and call a handwritten note better than a phone call, and they suggest hosts thank guests in a toast and again at the door. Post and Dan Post Senning also take etiquette questions on the institute’s Awesome Etiquette podcast.
