Anniversary Letter
An anniversary letter is the one gift that gets better with time. Flowers fade and dinners end, but a letter that names exactly what this year held — the hard month, the running joke, the ordinary Tuesday you would not trade — is something they will still have in ten years.
You do not need to summarise your whole relationship. Pick this year. What changed, what held, what you noticed about them that you never got around to saying out loud.
There is a practical argument for it too. The dinner gets photographed and forgotten; the letter goes in a drawer and gets found again during a bad week two years later. Write one every anniversary and the stack turns into a record of the marriage — the year you moved, the year one of you was ill, the year nothing happened and it was lovely.

What to say in a anniversary letter
- 1One specific memory from this year, told in detail — not "we had a great trip" but the moment on the trip you keep replaying.
- 2Something they did that you never properly thanked them for.
- 3A small habit of theirs you have quietly fallen in love with.
- 4Something difficult you got through this year, and what they were like while you were in the middle of it.
- 5A phrase or private joke from this year that would mean nothing to anybody else.
- 6What you are looking forward to in the year ahead, concretely.
One thing to skip: Avoid opening with "I can't believe it's been X years." Start with a moment instead — it earns attention in a way a milestone never does.
The difference one specific line makes
Same sentiment, two ways of saying it in a anniversary letter.
Most people write
“Happy anniversary. I can't believe it's been six years. I love you more every day.”
Write this instead
“Six years, and the thing I keep coming back to is you in the hospital corridor in March with two bad coffees, refusing to go home.”
Why it works: The first line could be printed on a card and posted to anybody. The second could only be written by one person, to one person, about one particular year — and that is the whole difference between a message and a letter.
Three ways to open a anniversary letter
The first line is the hard part. Steal one of these and fill in the brackets.
“A year ago today I had no idea [the thing that happened] was coming, and no idea you would be this good at it.”
“The moment I keep coming back to from this year is not the holiday. It is [ordinary moment].”
“I want to tell you what I noticed about you this year, because I do not think I ever said it out loud.”

Write in the blanks. The small words under each line tell you what to reach for — cross out any line that is not true of the two of you.
Dear their name,
A year ago today, what was happening in your life then.
The moment from this year I keep coming back to is the memory — you were what they were doing.
I never properly thanked you for the thing they did.
When the difficult thing happened, you what they did, and I noticed.
The thing you do without thinking that I love is the small habit.
Next year I want us to something concrete.
Happy anniversary. Your name

Questions people ask
What should I write in an anniversary letter?
Lead with one specific memory from the past year, say what it showed you about them, thank them for something concrete, and end with what you are looking forward to. Specificity is what makes it feel like it could only have been written by you, to them.
How long should an anniversary letter be?
Between 200 and 500 words is plenty. A shorter letter with three real details beats a long one full of general praise.
What do I write if this year was difficult?
Write about that. An anniversary letter that names the hard months and says you are still here is far more moving than one that pretends the year was smooth. Say what happened, say what they were like while it was happening, and say what you chose.
Should I write a new letter every anniversary?
If you can. Keep each one short and it stays a pleasure rather than a chore, and re-reading last year's before you write this year's is half the value — you notice how much you both moved.
Can I schedule it to open on our anniversary?
Yes. Write it whenever you like, set the opening date, and the link stays sealed with a countdown until the day arrives.

Write it tonight and schedule it to unlock in the morning. Being told something true before the day even starts is better than being told it over dessert.
