What to write

1. Say the number. Fifteen rarely gets a party, so the card carries more weight.
2. Acknowledge the busy years. Fifteen years in often means young children, work pressure and very little time.
3. Use the crystal tradition if you want a hook. It gives you both a line and a gift idea.
4. Look forward. Fifteen is a staging post, not a summary.

FAQ

What do you write for a 15th anniversary?

Name the fifteen years, acknowledge that this is often the busiest stretch of a marriage, and look forward rather than back.

What is the traditional 15th anniversary gift?

Crystal, which makes an easy card reference as well as a gift.

Is fifteen years a big anniversary?

It is a genuine milestone but rarely marked with a party, which is exactly why a thoughtful card stands out.

What do you write to your own partner?

Something specific about these fifteen years rather than the wedding — see what to write in an anniversary card.

What is a good short message?

“Happy 15th anniversary — fifteen brilliant years.”

How is it different from a 20th?

Fifteen usually lands mid-parenting and mid-career; twenty tends to arrive with a bit more breathing room. See 20th anniversary wishes.
