Send kids’ party invitations two to four weeks ahead, adult birthday invitations three to six weeks ahead, and holiday party invitations four to six weeks ahead. Put the RSVP deadline about one to two weeks before the party, or a few days before you owe anyone a final count. Allow more notice when guests need travel, childcare, or time off. The holiday range is the Emily Post Institute’s recommendation (source); the birthday ranges are our planning suggestions. None of these are rules every host has to follow.
If you already have a party date, the RSVP deadline calculator turns these ranges into a send-by date and a reply-by date for your occasion.
Quick answer: when to send invitations and set the RSVP deadline
| Occasion | Send invitations | Set the RSVP deadline |
|---|---|---|
| Kids’ birthday party | 2–4 weeks before | About 1 week before, or a few days before a venue needs numbers |
| Adult birthday party | 3–6 weeks before | 1–2 weeks before |
| Baby shower | 3–6 weeks before | 1–2 weeks before |
| Holiday party | 4–6 weeks before | 1–2 weeks before |
| Friendsgiving | 2–3 weeks before | About 1 week before, ahead of shopping or dish assignments |
| Graduation party | 2–6 weeks before | 1–2 weeks before |
| Housewarming or informal dinner | A few days to 3 weeks before | A few days before |
The send-by ranges for showers, holiday parties, graduations, and informal dinners come from the Emily Post Institute’s guidance linked in each row. The birthday and Friendsgiving ranges, and every RSVP deadline, are our planning suggestions, not findings from attendance studies. If a venue, caterer, or food order needs your count earlier, move the RSVP deadline earlier to match.
The useful question behind every row is what guests have to arrange before they can say yes. Then work backward from the date you need a reliable headcount. Dinner with nearby friends needs little preparation. A milestone birthday with hotel stays needs an earlier conversation, even if both events have twelve guests.
How far in advance should you send kids’ party invites?
Send kids’ party invites two to four weeks before the party, and ask parents to reply about a week before it. Go to the early end, four weeks, when you have a venue booking, a cap on the number of children, or a date during a school break. Two weeks is enough for a party at home with families who live nearby and already know your child.
Why not earlier? A party six weeks out is easy for a busy parent to forget. Why not later? Weekends fill up with soccer, swim lessons, and other birthday parties, and a parent who gets the invitation ten days out often already has the afternoon spoken for.
Before you send anything, settle the three details that decide a parent’s answer: the start and finish times, whether parents stay or drop off, and whether siblings are welcome. A parent choosing between “one child for two hours” and “the whole family for an afternoon” needs different information.
School-class invitations
If the guest list is the whole class, or every girl or every boy in it, check the school’s rules on handing out invitations before you count on the classroom as your delivery route. Many schools allow it only when every child is included. Teachers also need a day or two to get envelopes into backpacks, so add that to your timeline and send three to four weeks out rather than two.
If you’re inviting a smaller group from the class, send the invitations privately to the parents instead, and send them a little earlier than you would for close friends. Those families know you less well, so they need a longer runway, and a private message keeps your child out of the position of explaining at school who was and wasn’t invited.
Summer and school-break parties
A birthday that falls in late June, over winter break, or on a long weekend competes with travel. Send four weeks out, or even five, and say in the invitation that you understand some families will be away. For a party in the first two weeks of summer vacation, send before school lets out, while you still have a reliable way to reach the other parents.
Venue parties with a headcount deadline
Trampoline parks, pottery studios, and party rooms usually want a final number anywhere from three days to two weeks ahead, and they charge per child. Ask for that deadline when you book, then set your RSVP deadline a few days before it, so you have time to chase the two or three families who haven’t answered. Send the invitations four weeks before the party. That leaves roughly three weeks for replies and a week for follow-up before the venue’s cutoff.
Sending to parents by text
Most kids’ party invitations now go to a parent’s phone, not to the child. A text works well if each family gets its own message with the date, times, the address, and a clear way to reply. Sending the details once to a group thread does not, because the thread buries the information under replies, and you have no way to tell who has seen it. Keep the details somewhere each parent can find again, and ask for the reply you need: which adults are coming, how many children, and any allergies. Our page on kids’ birthday invitations and household RSVPs goes into the reply side.
When does a party need extra notice?
Move earlier when the event asks guests to make a booking or rearrange an existing commitment. A long drive with an overnight stay, a holiday weekend, a weekday celebration, or travel during a school vacation all push the send date toward the top of the range or past it.
For a graduation party, check the ceremony date and talk to the people whose attendance matters most before fixing your start time. For a surprise birthday, coordinate privately with the person helping the guest of honor arrive.
If the date is firm but the venue is not, send a brief heads-up to the people you most want there:
We’re planning a birthday lunch for November 7 and would love you there. Please keep the afternoon in mind; I’ll send the location and invitation by October 10.
Give a date for the details, and follow through. Avoid asking guests to book travel around a plan you may still change.
How do you choose an RSVP deadline?
Choose the RSVP deadline before you send the invitations. Work backward from the first decision that requires a count: a venue guarantee, catering order, seat reservation, or shopping trip.
Leave a few days between the guest deadline and that decision. That gives you room to follow up individually or correct a household count. If a venue needs numbers two weeks ahead, an RSVP deadline one week before the party is already too late.
For a flexible dinner at home, your deadline can be closer to the event. Tell guests the reason plainly: “Please reply by Wednesday so I can shop on Thursday.” A concrete date is easier to act on than “RSVP soon.”
A worked invitation timeline for a November 7 party
Here is an illustrative plan for a children’s birthday on Saturday, November 7, 2026, with a venue that requires final numbers on October 31. The venue deadline is an example, not an industry standard.
- October 10: send invitations. That gives families four weeks’ notice. Include the finish time, location, sibling policy, and October 28 RSVP deadline.
- October 26: remind households that have not answered. Mention the deadline and make a yes or no equally welcome.
- October 28: collect replies. Check adult and child counts against the venue’s rules.
- October 29 and 30: resolve missing or unclear answers. Contact those households privately before committing to a paid count.
- October 31: give the venue the final count. Keep unresolved replies separate from confirmed attendance and decide what extra capacity you can afford.
This leaves a three-day gap between the RSVP deadline and the venue deadline. If your venue requires numbers earlier, move the reply and follow-up dates earlier too.
Is one week too late? Do text invitations change the timing?
One week can work for a small, local party. Be candid about the short notice, share all the details at once, and make declining easy. If the people you most want there are unavailable, changing the date may be more useful than sending repeated reminders.
Text and email skip postal transit time, but guests still need time to arrange their lives, so the ranges above don’t shrink much for a digital invitation. What changes is the follow-up: a reminder costs you thirty seconds instead of another stamp. Choose a channel your guests use, and keep the details somewhere they can find again. A delivered invitation also does not tell you whether someone has decided to attend.

Keep the replies with the invitation
HeadOnOver sends private invitations by email or as texts from your own phone and collects household RSVPs with adult and child counts on each guest’s invitation page. Guests do not need an account. When you choose to send a reminder, it goes to households that have not answered; reminders do not send themselves. You set the timeline and can see the replies in one place.
