How to say happy birthday in French

Happy birthday in French is joyeux anniversaire. Bon anniversaire means the same thing and is equally common. Both work with anyone, a close friend or a client, because neither contains tu or vous.

The ways to say it

How to use it

The two phrases differ by their first word only: one wishes a joyful birthday, the other a good one. Pick either. The second exchange below uses bon anniversaire in a formal setting, with vous, and nothing about it is less warm.

The first exchange also shows how French talks about age: it uses the verb to have. You have twenty years; you are not twenty. The question and the answer both follow that pattern.

Watch out

Both phrases carry a liaison: the last letter of the first word sounds at the start of the second, because that one opens on a vowel. The tie in the examples marks it, with the sound you hear under it.

In a real conversation

Each exchange is a line and its reply. Greyed letters are written and not pronounced. A tie marks a liaison, with the sound you hear under it. A label under a verb names its tense when it is not the present.
