- Give the start time and the end time. A birthday is the one invitation where guests need to know when it stops.
- The age is optional. Naming it makes the party about the milestone; "a big one" is a complete answer.
- A child's party needs three things an adult party does not: drop-off or stay, what the children eat, and what to bring.
- A surprise party has two arrival times. Put the guests' one first and the secrecy line near the top.
- Gifts, no gifts, or a donation instead: one honest line, and nobody has to ask you in private.
What a birthday invitation must say
A birthday has fewer moving parts than a wedding, which is why the wording gets rushed and why the same five questions arrive by message all week. Everything a guest needs fits on one screen, and it is worth writing all of it even for eight friends in your kitchen.
One fact matters more here than anywhere else: the end time. Guests leaving a wedding know the night is over when the music stops. Guests at a birthday are guessing, and a parent at a child's party is planning the whole of Saturday around your answer.
- Whose birthday it is, and whether the age is part of the invitation.
- Who is inviting: the person themselves, a partner, a parent, a group of friends.
- The day, the date and the start time, with the day of the week written out.
- The end time, or the shape of the evening: dinner at eight, cake at ten, music until late.
- The address in full, and the part that is hard to find: the buzzer, the back gate, the room upstairs.
- Food and drink: a meal, something to pick at, or a note that people should eat first.
- Anything to bring or wear, and how to reply, with a date.
The age question
No rule says an age belongs on an invitation, and none says leaving it off is coy. It is a decision about tone. Naming the number makes the party about the milestone, which is what most fortieths are for. Leaving it out makes it about the person, which is what someone who dislikes a fuss wants.
The middle answer is more useful than either extreme: say it is a milestone without saying which one. Whichever you choose, be consistent. "A big one" on the card and a numeral on the cake are two different decisions arriving on the same evening.
Anna is forty. There will be cake, and there will be denial.
Thomas turns fifty on the twelfth, and we are marking it properly.
It is a big one. We are not saying which one. Come anyway.
Sofia is having a birthday. The number is not the point; the dancing is.
A round number, a long table, and everyone who has put up with me.
Milestone birthdays, one line each
Every decade wants a different invitation, and not because of the number. What changes is who is in the room and what they need to plan around. An eighteenth is written for the parents as much as the guests; a seventieth is written for people who want to know where to park.
Kasia is eighteen. Saturday 12 May, seven until midnight, at the hall on Rynek Street. Parents are collecting at midnight.
Eighteen years, and we are letting her choose the music. You are invited.
Bram is thirty. Drinks at eight, dinner at nine, no speeches and no theme.
Anna is turning forty and we are making a fuss. Saturday 12 May, from seven.
Forty years, forty friends, one long table. Please come.
Thomas is fifty, and everyone who has known him, from school to the boat club, is invited on the twelfth.
Fifty years of Sofia. Lunch at one, in the garden, until it gets cold.
Marta is sixty. Sunday lunch at the Kastanienhof, midday until four. Bring the children.
Papa turns seventy-five. Saturday, two until six, at home. Chairs, cake, no speeches unless you insist.
Afternoon tea for Helena's ninetieth, Saturday at three, in the church hall. There is a lift.
| Milestone | What the party is really for | Wording that works |
|---|---|---|
| 18th | A first adult party, parents in the background | Direct, with the end time spelled out |
| 30th | A last big night before the diaries fill up | Modern and warm; the old-age joke is tired |
| 40th | An occasion, and the age is usually said | Confident: name the number, name the fuss |
| 50th | Every era of one life in a single room | Warm and a little formal; half are strangers |
| 60th | Family first, an afternoon rather than a night | Plain, with timings that can be planned around |
| 70th and over | Seating, daylight and getting home | Short sentences: time, address, parking |
Children's parties
A child's party invitation is read by an adult deciding what their afternoon looks like. Three facts decide it: whether they are staying, when it ends, and what their child will be fed. Leave one out and you will answer the same message eleven times.
Drop-off or stay is the line people are shyest about writing, so write it. The parent of a five-year-old wants to be told they may stay; the parent of a nine-year-old wants to be told they can go.
Emil is turning six. Saturday 12 May, three until five, at home. Parents very welcome to stay for coffee.
Nina is seven. Come and play, Saturday, two until half past four, at the hall on Lindenweg. Drop-off is fine; we will be there throughout.
A pool party for Luca's eighth. Saturday, ten until twelve. Bring swimming things, a towel and a snack.
Sofia is five. Cake, a bouncy castle and far too much running. Two until four; we will feed them lunch.
There are nuts in the house. Tell us about any allergies when you reply and we will keep a plate aside.
No presents, please, Emil has plenty. If you would like to bring something, a book he has not read would be perfect.
- A start time and an end time, both, so a parent can plan the rest of the day.
- Drop-off or stay, said in words, so nobody has to guess.
- What the children will eat and when, so a parent can feed them beforehand or not.
- Allergies: ask on the invitation rather than hoping a parent volunteers it.
- What to bring, and a number to ring if you are taking children somewhere.
Surprise parties
A surprise party is the only invitation with two arrival times, and nearly every one that goes wrong goes wrong there. Guests must be inside and quiet before the guest of honour walks in, so their time is not the party's time. Give them a hard arrival time and say why.
Put the secrecy line near the top, where it is read, not at the bottom next to the parking. And say who is handling the other end: what the guest of honour thinks is happening, and who is bringing them.
It is a surprise. Please do not mention it to Thomas in person, by message, or anywhere he might see it.
Anna does not know. Please arrive by half past seven; she arrives at eight.
Guests from 7.30. Sofia walks in at 8.00, believing she is going out for a quiet dinner.
Be in and settled by ten to eight. Mateo is being collected from the station by his sister.
If you cannot come, tell us rather than telling him. The reply goes only to us.
Park on the next street rather than outside, and come in through the garden gate.
Gifts, no gifts, and a donation instead
Saying nothing about gifts is a complete answer, and at most birthdays it is the right one. But "no gifts" at a birthday behaves differently from "no gifts" at a wedding: it is meant more often and ignored more often, so the line has to be warm and specific enough to be believed.
A donation instead of a present works when it is one line, one cause and one link, and when it asks nobody to prove anything. Keep the invitation to a sentence and put the rest on the guest page.
No presents, please. Your company is the whole point.
Nothing wrapped. If you want to bring something, bring a bottle and a story about me I have not heard.
Anna would rather not have presents. If you would like to mark the day, she is collecting for the animal shelter.
Instead of gifts we are raising money for the hospice that looked after our family. Anything at all, and nothing is expected.
Seventy years of things. Please bring none of them, just come.
Formal wording
Formal birthday wording exists for the occasions that earn it: a sixtieth dinner, an eightieth lunch, a party held in someone's honour rather than thrown by them. Third person, the date and hour spelled out, no contractions, the reply on its own line. Formality without a reason is the trap: a card requesting the pleasure of your company at a thirtieth in a bar reads as a joke the reader is not in on.
Mr and Mrs Peter Klein request the pleasure of your company at a dinner in celebration of the sixtieth birthday of Mrs Marta Klein, on Saturday, the twelfth of May, at seven o'clock in the evening.
You are cordially invited to a luncheon in honour of Professor Anna Weber, on the occasion of her seventieth birthday.
The family of Helena Nowak request the pleasure of your company at afternoon tea to mark her ninetieth birthday.
In celebration of eighty years of David Weber, his children invite you to dinner at Villa Rosa.
Dinner will be served at eight o'clock. Carriages at midnight.
Modern wording
The modern register is the first person and your own voice: one warm sentence, then the facts, then stop. It suits nearly every birthday, and the only real trap is padding, three sentences of feeling where one would have landed.
I am having a birthday and I would like you there. Saturday 12 May, from seven, at ours.
Anna is turning forty. Come and eat, drink and stay too late.
We are borrowing the garden, the long table and the good glasses for Thomas's fiftieth.
Drinks for Bram's thirtieth. Come after work and stay as long as you like.
Lunch in the garden for Lena, Sunday from one. Bring the children, bring a hat.
Playful wording
Playful works when the joke lives in the first line and the facts underneath stay straight. A guest who cannot find the time because the invitation is being funny about the time will message you, and you will lose both the joke and the evening.
Anna is forty. There will be denial, and there will be cocktails.
I have survived thirty years. Come and watch me start on the next one.
Old enough to know better, still doing it anyway. Saturday, from eight.
Cake at nine. Attendance strongly encouraged, presents strongly discouraged.
It is not a big one. We are having a big one anyway.
Come for the cake, stay for the terrible photographs.
The reply line
Birthdays are answered worse than any other invitation, because a casual invitation reads as an optional one. The fix is three things: a date written as a date, one place to answer, and a reason. A table booking, a caterer, a headcount; guests reply to a reason.
Set the date a week or two before the party, not three days, and ask for the two things you will use: how many are coming, and anything they cannot eat. On a digital invitation the form sits on the page, and the reply-by date closes it when it passes.
Please reply by 5 May. The restaurant needs the number by then.
RSVP by 5 May using the link. Tell us how many of you are coming and anything you do not eat.
Let us know by Sunday so we know how much to cook.
Scan the code to reply. Thirty seconds, and it saves us a week of messages.
Reply by 5 May, and say whether your children are coming, so we can count the cake.
Wording mistakes at birthdays
Each of these costs either a message you have to answer or a guest who does not turn up. None of them costs anything to avoid.
- No end time, so parents cannot plan and nobody knows whether dinner is included.
- "Bring nothing" on the invitation and a table of presents by the door.
- The surprise mentioned in a group chat that includes the guest of honour.
- One arrival time on a surprise invitation, so half the room walks in after the surprise.
- A child's party with no word about food, so eleven parents ask separately.
- An age printed on the card that the birthday person never agreed to.
- "Drinks at ours" with no address, because everyone has been before, except the two who have not.
- A theme mentioned once and never explained, so half the guests come in costume.
- "Let me know" instead of a reply date, followed by a week of chasing.
- A joke that runs past the first line and swallows the address.
FAQ
- What should a birthday invitation say?
- Whose birthday it is, who is inviting, the day and date, the start and end times, the full address, whether there is food, anything to bring, and how to reply by a date. The end time is the one people leave out and the one guests most want.
- Do you have to put the age on a birthday invitation?
- No. Naming the number makes the party about the milestone; leaving it out makes it about the person. If you want the occasion without the number, "it is a big one" is a complete answer.
- How do you word a surprise party invitation?
- With two times and a secrecy line near the top: "Anna does not know. Please arrive by half past seven; she arrives at eight." Say what the guest of honour thinks is happening, and ask people to reply to you rather than mention it to them.
- How do you word a children's party invitation?
- Start time and end time, the address, whether parents drop off or stay, what the children will eat, what to bring, and a question about allergies. Each one you leave out becomes a message.
- How do you say no gifts on a birthday invitation?
- Plainly and warmly, once: "No presents, please. Your company is the whole point." If you would rather have something else, name it and keep it small, a bottle, a plant, or a donation to one named cause.
- How far in advance should a birthday invitation go out?
- Three to four weeks for a party, six to eight for a milestone where people travel. A child's party is usually two to three weeks: far enough ahead to beat the other parties, close enough that parents still have the date in mind.
- How do you word a milestone birthday invitation?
- Decide first whether the number is on it, then match the register to the room. An eighteenth wants the end time in writing, a fortieth can name the number, and a seventieth wants seating, parking and how long it will last.
- Can you send a birthday invitation as a link?
- Yes. A digital invitation is a web page with one link or a QR code; guests open it in any browser, with no app and no account, and reply on the page with their party size and any dietary needs. Vowly Event shows the page in nine languages, so each guest reads it in theirs.
