French Date Formats Explained

When I first moved to France, I thought I had mastered the basics: bonjour, pain au chocolat, and how to dodge small talk with my neighbours. But then came the day I tried to book a train ticket. I proudly typed 05/08/2024, only to discover I’d bought a ticket for August 5th, not May 8th. I spent the entire summer explaining this mistake to every conductor on the TGV. Each one nodded politely, the way French people nod when they know you have suffered enough.

Dates look simple, but French formats hide tiny traps. Thankfully, once you know the system, the confusion disappears. So let’s straighten out the numbers, the order, the words, and the quirks that once made me miss the Lyon train entirely.

The Quick Primer

French dates use day–month–year order. Always. No exceptions.
The format looks like:

dd/mm/yyyy
25/12/2025 → 25th of December, 2025

French also writes dates fully in words, placing the day number first, then the month, then the year.

Now that you know the skeleton, let’s build the muscles, clothes, and elegant scarf on top.

The Standard French Date Format

Here are the most common ways dates appear in France:

Numeric Format

dd/mm/yyyy
14/07/2025 → July 14th, 2025 (Bastille Day)

There is no switching like in American English. If you see 07/02/2025, it is 2 February, not July 2nd.

Written-Out Format

le + day number + month + year

Example:
le 3 avril 2024 /lə tʁwa a.vʁil dø mil katʁə/ — April 3rd, 2024

Important detail:
You normally include le before the date when it’s alone in a sentence.

Capitalization Rule

Months are not capitalized in French.

Correct: mai, juin, septembre
Incorrect: Mai, Juin, Septembre

English muscles twitch here, but French stays calm and lowercase.

The Months in French (With IPA)

Yes, août /ut/ really has that sneaky silent ô.

Talking About Dates in Natural Sentences

French prefers full phrases when dates appear in conversation.

“Today is May 8th.”

Nous sommes le 8 mai.
/nu sɔm lə ɥit mɛ/
It’s May 8th.

“My birthday is on July 14th.”

Mon anniversaire, c’est le 14 juillet.
/mɔ̃ na.ni.vɛʁ.sɛʁ sɛ lə katɔʁz ʒɥi.jɛ/
My birthday is July 14th.

“I arrived on March 3rd.”

Je suis arrivé le 3 mars.
/ʒə sɥi a.ʁi.ve lə tʁwa maʁs/
I arrived on March 3rd.

When To Use “Premier” for the First Day

Unlike English, French uses premier /pʁə.mje/ only for the 1st of the month.

le premier juin
/lə pʁə.mje ʒɥɛ̃/
June 1st

But all other numbers stay normal:

le 2 juin
le 15 juin
le 30 juin

When I mixed this up, I once told someone I had moved to Paris on “le un août.” He blinked at me like I’d just confessed to eating cheese without bread.

How to Say the Year

Years are spoken as full numbers.

2025
deux mille vingt-cinq /dø mil vɛ̃ sɛ̃k/

1999
mille neuf cent quatre-vingt-dix-neuf /mil nœf sɑ̃ katʁə vɛ̃ dis nœf/

French never breaks them into “twenty twenty-five.”

Writing Dates in Formal Contexts

France sometimes uses more formal writing in documents:

le 25 décembre 2025
Paris, le 12 avril 2024 — used at the top of letters
Fait le 3 septembre 2023 — “Done on September 3rd, 2023”

These are common in contracts, letters, and official forms.

Saying Dates Without the Year

You simply omit the year:

le 14 juillet /lə katɔʁz ʒɥi.jɛ/
the 14th of July

le 22 octobre /lə vɛ̃t‿døz ɔk.tɔbʁ/
October 22nd

Ordinal Numbers and Dates

French rarely uses ordinal numbers except for premier.

You do NOT say:

✗ le deuxième mars
✗ le quatrième août

You stick to the plain numbers.

Region Notes

In Belgium and Switzerland, the formats are generally the same as France.
In Québec, people speak the same way but may sometimes write:

aaaa-mm-jj
2025-12-14

This resembles ISO format because Québec bureaucracy likes things tidy.

Québec also uses slightly different month pronunciations, but the structure stays the same.

Wrapping Up With a Yak-Sized Bow

Once you get the rhythm of French dates, everything clicks into place. Day first, month second, year last—like lining up for a perfect croissant. And once you stop confusing 05/08 with 08/05, the TGV conductors will stop giving you that pitying smile.
