Days of the week (lundi, mardi)

Here are the days of the week. Unlike in English, they are not capitalized in French unless they start a sentence:

FrenchEnglish
lundiMonday
mardiTuesday
mercrediWednesday
jeudiThursday
vendrediFriday
samediSaturday
dimancheSunday

To talk about an event on a specific day, just use the day by itself. You don't need a preposition like "on":

Monday, I am starting a new project.
Lundi, je commence un nouveau projet.
Are you free Wednesday?
Tu es libre mercredi ?
Saturday, we are going to the movie theater.
Samedi, on va au cinéma.

Recurring Habits

To express a recurring weekly habit (like "on Mondays" or "every Tuesday"), simply add the definite article le before the day.

This changes the meaning from a one-time event to a regular occurrence:

On Mondays, we go to the pool.
Le lundi, nous allons à la piscine.
On Tuesdays, she works at home.
Le mardi, elle travaille à la maison.
On Sundays, there are no buses.
Le dimanche, il n'y a pas de bus.
