18th, 21st, 30th, 40th, 50th, 60th and 70th Birthday Wishes
Each decade wants a different card. Eighteen is encouragement, forty is reassurance, seventy is tribute — and the age joke stops being funny somewhere around fifty.
18th
Encouragement, and a note of welcome rather than warning.
- 1
Eighteen. Everything from here is yours to decide, which is the best and worst part.
- 2
Happy eighteenth. You are legally an adult and nobody feels like one, including the adults.
- 3
Happy eighteenth birthday. Go carefully and have a brilliant time.
- 4
Eighteen. I am proud of you and I am slightly terrified. Both are normal.
21st
- 5
Twenty-one. Old enough to know better and young enough not to. Enjoy it.
- 6
Happy twenty-first! Have an excellent night and a difficult morning.
- 7
Happy twenty-first. This is the year everything starts feeling possible.
30th
Most people find thirty harder than forty. Reassurance works better than jokes.
- 8
Thirty. Everyone I know says their thirties were much better than their twenties. Happy birthday.
- 9
Happy thirtieth. You have got it more together than you think.
- 10
Thirty and thriving. Happy birthday.
- 11
Happy birthday. Thirty is not a deadline, whatever the internet says.
40th
- 12
Forty and completely undiminished. Happy birthday.
- 13
Happy fortieth. You are better at everything than you were at thirty and you know it.
- 14
Forty. A very good decade to be starting. Happy birthday.
- 15
Happy fortieth birthday — the fuss is entirely deserved.
50th
The age jokes start landing badly here. Switch to admiration.
- 16
Fifty. Half a century of being consistently good company. Happy birthday.
- 17
Happy fiftieth. You have built a genuinely good life and it shows.
- 18
Fifty, and the best decade yet. Happy birthday.
- 19
Happy fiftieth. You look about forty and behave about thirty, which is the correct combination.
60th
- 20
Sixty. You have earned the right to please yourself entirely. Happy birthday.
- 21
Happy sixtieth. Thank you for sixty years of being exactly who you are.
- 22
With warmest wishes on your sixtieth birthday.
70th and beyond
These are tributes. Say what they have meant.
- 23
Seventy. Four generations of this family have been looked after by you. Happy birthday.
- 24
Happy seventieth. You have been the fixed point for all of us for a very long time.
- 25
Eighty. There is nobody like you and there is not going to be. Happy birthday.
- 26
With love and admiration on your eightieth birthday.
For someone who hates the fuss
- 27
Fifty. Noted, unmarked, no singing. Happy birthday.
- 28
Happy birthday. I have not organised anything and I never will.
- 29
Acknowledged only. Have a very quiet day.
Organising a milestone party
- 30
Ask them first. A surprise party is a gift to the organiser as often as to the guest.
- 31
Check what they actually want: a party, a dinner, or nothing.
- 32
For a seventieth or eightieth, a book of messages from everyone is remembered longer than any party.
What each decade is actually anxious about
Write to the worry and the card lands. Ignore it and you get another age joke.
- 33
Eighteen: that everyone expects them to know what happens next. They do not.
- 34
Thirty: that they are behind. Almost everyone at thirty believes this.
- 35
Forty: that the interesting part is over. It is not, and saying so helps.
- 36
Fifty: being seen as older rather than as themselves.
- 37
Sixty and beyond: being written off. Address them as a person with plans.
Milestone cards from a group
- 38
A book of messages from everyone, collected quietly, beats any party or gift at seventy and eighty.
- 39
Ask each contributor for one specific memory rather than a signature.
- 40
One person collates. Do not circulate a book of blank pages at a party.
- 41
Include the great-grandchildren, however illegibly.
When the milestone falls in a hard year
- 42
Happy fiftieth. It has not been the year for a party and this is not one. Just marking it.
- 43
Happy birthday. A big number in a difficult year. Thinking of you.
- 44
Happy sixtieth. We will do it properly when you are ready.
Milestones people forget to mark
- 45
The twenty-fifth, which falls between two celebrated ones and is usually ignored.
- 46
The thirty-fifth and forty-fifth, marked by almost nobody.
- 47
Ninety and beyond, where a card is genuinely rare and genuinely valued.
- 48
The first birthday after a bereavement, which is not a milestone by number but is one in fact.
Questions people actually ask
What do you write in a 50th birthday card?
Switch from jokes to admiration. Age jokes work at thirty and land badly at fifty; a line about what they have built does not.
What do you write for a 70th or 80th birthday?
Treat it as a tribute rather than a greeting. Say what they have meant to the people around them — that is the card that gets kept.
Is it rude to joke about someone turning 40?
It depends entirely on them, and a large minority quietly dislike it. If you are unsure, they mind.
What is the best gift for a 70th or 80th birthday?
A book of messages collected from everyone, one specific memory each. It is remembered far longer than a party and costs almost nothing.
What do you write for a milestone in a difficult year?
Mark it without demanding celebration. "A big number in a difficult year. Thinking of you" acknowledges both and asks nothing.
