The RSVP deadline looks like a small detail, but almost everything after it depends on it: the caterer's count, the seating plan, the place cards, the shuttle. Set it too late and you rush the last weeks; set it too early and guests who have not made plans yet reply "no" or not at all. This guide shows how to work out the right date for your wedding and how to word it.
The short answer: two to three weeks before
Etiquette guides, including the Emily Post Institute's wedding planning timeline and its advice on response cards, give the same general range: replies due about two to three weeks before the wedding, with invitations sent six to eight weeks ahead. That leaves guests four to six weeks to answer, and leaves you time to chase the last replies before your vendors need numbers.
The general range is a starting point. The real deadline comes from your contracts.
Work backwards from your vendors
Your caterer, venue and other suppliers each have a date by which they need final numbers. Your deadline must come before the earliest of them, with time in between to follow up.
- List every "final numbers" date in your contracts: caterer (often with meal choices), venue (seating and rentals), cake, transport, hotel room block.
- Take the earliest one. That is your hard limit.
- Go back about seven days. That week is for reminders and phone calls to guests who have not answered.
- Move it to a weekday that is not a public holiday, so you can chase replies the next morning.
- Check it against the two-to-three-week range. If your date is much earlier, send invitations earlier too, so guests still have about a month to reply.
An example. The wedding is on Saturday, June 12, 2027. The caterer needs final numbers and meal choices by Saturday, May 29. Going back seven days gives Saturday, May 22; moving to a weekday gives Friday, May 21, 2027. Invitations then go out by Friday, April 16, eight weeks before the wedding, which leaves guests five weeks to reply.
Deadlines for different kinds of weddings
| Wedding | Typical RSVP deadline | Why |
|---|---|---|
| Local wedding, one event | 2 to 3 weeks before | Matches most caterers' final-count dates |
| Destination wedding | Earlier, often 6 to 8 weeks before | Hotels, flights and room blocks need numbers well ahead |
| Several events (welcome drinks, brunch) | The earliest event's deadline | One reply-by date for everything is easier for guests |
| Wedding on a holiday weekend | 1 week earlier than usual | Guests and vendors are slower to respond |
| Small wedding at home or in a restaurant | 1 to 2 weeks before | Fewer people to count; ask the restaurant |
These are rules of thumb, not requirements. When a contract says otherwise, the contract wins.
How to write the deadline
A deadline only works if every guest reads the same date:
- Write it in full, with the month as a word: "Kindly reply by May 21, 2027". A date like 05/21/27 reads differently in different countries.
- Use the same date everywhere: invitation, reply card, website and reminder messages.
- Avoid relative dates such as "four weeks before the wedding". Guests should not have to count.
- Put it first in the reply line, before the address or the code.
Wording you can copy:
- Formal: "The favor of a reply is requested by May 21, 2027."
- Relaxed: "Please let us know by May 21, 2027."
- On the website: "Replies close on May 21, 2027. After that, please message us directly."
Our guide on putting your website on the invitation has wording for every card in the envelope.
Online replies and mailed replies
If guests reply by mail, add a few days of post to your plan: a card posted on the deadline may arrive days later. Many couples write a slightly earlier date on the paper reply card for that reason. If some guests reply by post and others online, print one date for both and simply allow for the post when you count.
Online replies arrive instantly, but they raise one question: what happens after the date? Some forms keep accepting replies; others close on their own. A form that closes is usually better. Late guests then contact you directly, so you know to check with the caterer before you say yes.
Mind the time zone if guests live abroad. A form that closes "at midnight" closes at midnight somewhere; make sure it is the time zone of your wedding.
If you need to move the deadline
Sometimes the date has to change: the caterer extends their own date, or a wave of guests is still undecided because of travel.
- Moving it later: tell everyone who has not replied, with the new date written in full. Update the website first.
- Moving it earlier: avoid this if you can. If you must, send every guest a personal message, not only those who have not replied, and explain briefly why.
- Reopening an online form: change the reply-by date, check the form is open again on your own phone, then send the message.
After the deadline
The day after your deadline, download your replies and compare them with your guest list. Some guests will not have answered; that is normal at every wedding. Our guide to what to do when guests don't RSVP has a follow-up plan and messages you can send, and the guide to wedding RSVP questions covers which answers to pass on to each vendor.
How our wedding websites handle the deadline
You set your reply-by date in your panel, and guests see it on your RSVP page. The form closes on its own at the end of that day, in your website's time zone, and guests who open it later see that replies are closed. You can change the date in your panel at any time, which also reopens the form. Replies, totals and an Excel or CSV download are in your panel, and you can add replies you received by phone yourself. See the RSVP features, try the reply form in the Olive & Ivory demo, and read when to send your wedding website for the full timeline from save the dates to the day.

FAQ
How far before the wedding should the RSVP deadline be?
About two to three weeks before the wedding for most local weddings, and at least a week before your caterer's or venue's final-numbers date. Destination weddings often need replies six to eight weeks ahead, because hotels and travel need numbers earlier.
Is one month before the wedding too early for an RSVP deadline?
Not if your vendors need numbers early or many guests travel. Just send the invitations earlier as well, so guests still have about a month to reply. For a local wedding with flexible vendors, two to three weeks is usually enough.
Should the RSVP deadline be on a weekday or a weekend?
A weekday is easier. You can look at the replies the next morning and start calling guests who have not answered, and vendors are reachable if you need to confirm a late change.
What happens to late replies after the deadline?
Thank the guest and check with your caterer before confirming. If your online form closes after the deadline, late guests contact you directly, so you can add them yourself and none slip through unnoticed.
