When to send invitations and set the RSVP deadline
Vishra, Vishful Studio. . About 5 minutes to read.
There is no law about when invitations go out, only habits that most guests expect. These are the common ranges, and the way I work backwards from the party so nothing lands too late.
The common ranges
Treat these as common guidance, not rules. A busy season, a long journey or a big guest list are all reasons to go earlier.
| Event | Invitations out | Replies by |
|---|---|---|
| Child’s birthday party | 2 to 3 weeks before | About 1 week before |
| Adult birthday party | 3 to 4 weeks before | About 1 week before |
| Holiday party | 4 to 6 weeks before | About 1 week before |
| Wedding save the date | 6 to 8 months before | No reply needed |
| Wedding invitation | 6 to 8 weeks before | 3 to 4 weeks before |
Whatever the event, if a caterer, venue or bakery needs a final number, that date usually lands 1 to 2 weeks before the day. Your reply-by date has to come before it, with a few days spare for chasing the people who forget.
Why the ranges are what they are
Children’s parties
Family weekends fill up, but not months ahead. Two to three weeks is enough notice for parents to keep the afternoon free without the invitation getting lost on the fridge. Much earlier and people forget; much later and the weekend is gone.
Adult parties
Adults juggle more: work travel, other plans, childcare. Three to four weeks gives them room to arrange things.
Holiday parties
December weekends are the most contested dates of the year. Four to six weeks gets you onto calendars before the office party and the family visits do.
Weddings
Weddings often involve travel and time off work, so the save the date carries the early notice and the invitation carries the details. A destination wedding, or one on a holiday weekend, is a good reason to go earlier on both.
Working backwards, two examples
I always start from the party and count back, because the latest date that matters is usually the vendor’s, not yours.
A first birthday on Saturday 17 April 2027
- Party: Saturday 17 April.
- Replies by: Saturday 10 April, one week before, which leaves time to order the cake to the right size.
- Invitations out: between 27 March and 3 April, two to three weeks before.
- If you are printing cards: order them about ten days before you plan to hand them out, or whatever your print shop’s turnaround is, plus a few days for post.
A wedding on Saturday 12 June 2027
- Save the dates: between 12 October and 12 December 2026, six to eight months before.
- Invitations out: between 17 April and 1 May 2027, six to eight weeks before.
- Replies by: between 15 and 22 May, three to four weeks before.
- Final headcount to the caterer and venue: between 29 May and 5 June, one to two weeks before, or whatever date your contract names.
The party timeline planner does this arithmetic for any date and event type, and gives each milestone an add to calendar link so the reminders come to you.
A reply-by date only works if guests notice it. Put it on the card itself, next to the RSVP button if the invitation is online, and in the message you send with a digital invitation.
Digital invitations change the maths a little
A link arrives the moment you send it, so there is no posting time to allow for. That makes it tempting to send late. Resist it: guests still need the same notice to clear their diaries, so keep to the same ranges as paper.
What digital does change is the follow-up. A short reminder message a few days before the reply-by date is normal and kind, and much easier than chasing people by phone after it.
When some replies never come
Some guests will miss the date. Give it a day, then send a friendly personal message rather than a group one. For the headcount, count anyone who has not replied by your vendor’s date as a likely yes for food and seating; it is easier to have a little spare than to run short.
Writing the reply line itself? Invitation wording: what goes where covers that.
