French calendar vocabulary is built around simple, reusable words for days, months, and seasons. The main skill is not only memorizing the words, but also knowing how French speakers write dates, use articles such as le, choose en or au, and avoid English-style capitalization.
Reader Note: In standard French, the names of days and months are normally written in lowercase. This is one of the first differences English speakers notice: Monday in July becomes lundi en juillet, not Lundi en Juillet.
French Days Of The Week
The French week is called la semaine. The seven days are les jours de la semaine. In everyday writing, each day stays lowercase unless it begins a sentence.
| English | French | Common Short Form | Useful Example |
|---|---|---|---|
| Monday | lundi | lun. | lundi matin — Monday morning |
| Tuesday | mardi | mar. | mardi soir — Tuesday evening |
| Wednesday | mercredi | mer. | mercredi après-midi — Wednesday afternoon |
| Thursday | jeudi | jeu. | jeudi prochain — next Thursday |
| Friday | vendredi | ven. | vendredi dernier — last Friday |
| Saturday | samedi | sam. | samedi matin — Saturday morning |
| Sunday | dimanche | dim. | dimanche soir — Sunday evening |
How To Use Days In A Sentence
- Je pars lundi. — I am leaving on Monday.
- Le lundi, je travaille. — On Mondays, I work.
- Nous avons cours mardi. — We have class on Tuesday.
- Ils arrivent dimanche. — They arrive on Sunday.
The small word le changes the meaning. Without le, a day often means one specific upcoming or past day. With le, it can mean a repeated habit: le vendredi means on Fridays or every Friday.
Weekday, Weekend, And Calendar Day
un jour
A day in the general sense.
Il y a sept jours dans une semaine.
un jour de semaine
A weekday, usually Monday to Friday.
Les bureaux ouvrent les jours de semaine.
le week-end
The weekend. In Canada, la fin de semaine is also common.
Je voyage le week-end.
French Months Of The Year
A month is un mois. The months in French are also written in lowercase in normal sentences. Several month names look close to English, but pronunciation and accents matter.
| Month Number | English | French | Common Short Form | Season In France |
|---|---|---|---|---|
| 1 | January | janvier | janv. | hiver |
| 2 | February | février | févr. | hiver |
| 3 | March | mars | mars | printemps |
| 4 | April | avril | avr. | printemps |
| 5 | May | mai | mai | printemps |
| 6 | June | juin | juin | été |
| 7 | July | juillet | juill. | été |
| 8 | August | août | août | été |
| 9 | September | septembre | sept. | automne |
| 10 | October | octobre | oct. | automne |
| 11 | November | novembre | nov. | automne |
| 12 | December | décembre | déc. | hiver |
How To Use Months In French
The usual preposition before a month is en. French does not use in the January or on July in the same way English does.
- en janvier — in January
- en avril — in April
- en août — in August
- au mois de décembre — in the month of December
The phrase au mois de is slightly more explicit. It is useful in formal writing, travel planning, school calendars, and administrative dates: Les inscriptions ouvrent au mois de septembre.
Writing Dates In French
French date order normally follows day + month + year. The article le appears before the number when the date is written in a sentence.
| English Meaning | French Form | Note |
|---|---|---|
| June 18, 2026 | le 18 juin 2026 | Day comes before month. |
| on May 4 | le 4 mai | No capital letter for mai. |
| July 1 | le 1er juillet | Use 1er for the first day of the month. |
| Tuesday, March 3 | mardi 3 mars | The day name stays lowercase. |
| 03/04/2026 | 3 avril 2026 | In French usage, this often means 3 April, not March 4. |
Date Tip: The first day of the month is special: le 1er is read as le premier. For all other dates, French uses normal numbers: le 2, le 3, le 14, le 31.
French Seasons
A season is une saison. The four seasons in French are useful for weather, travel, school terms, clothing, holidays, and nature vocabulary. Like days and months, season names are normally lowercase.
| English | French | Usual Preposition | Example |
|---|---|---|---|
| Spring | le printemps | au printemps | Les fleurs poussent au printemps. |
| Summer | l’été | en été | Il fait chaud en été. |
| Autumn / Fall | l’automne | en automne | Les feuilles changent en automne. |
| Winter | l’hiver | en hiver | Il fait froid en hiver. |
Why It Is “Au Printemps” But “En Été”
French uses au printemps because printemps is treated with le: à + le becomes au. The other seasons commonly take en: en été, en automne, and en hiver.
- Je voyage au printemps. — I travel in spring.
- Nous nageons en été. — We swim in summer.
- Les cours reprennent en automne. — Classes resume in autumn.
- On porte un manteau en hiver. — People wear a coat in winter.
Calendar Grammar That Learners Often Need
Lowercase Is The Normal Rule
French treats days and months as common nouns. This means lundi, mardi, janvier, and décembre are not capitalized inside a sentence. They only take a capital letter at the beginning of a sentence or in special title formatting.
- Correct: Nous partons vendredi.
- Correct: Elle revient en octobre.
- Not Standard In A Sentence: Nous partons Vendredi.
- Not Standard In A Sentence: Elle revient en Octobre.
Plural Days And Repeated Actions
When a day name refers to repeated days, French can use the plural. The final -s appears in writing, even if it is often silent in speech.
| Meaning | French | Use |
|---|---|---|
| every Monday | tous les lundis | Regular weekly action |
| every Tuesday morning | tous les mardis matin | Repeated day plus time of day |
| on Fridays | le vendredi or les vendredis | Habit or schedule |
| several Sundays | plusieurs dimanches | More than one Sunday |
Next, Last, Today, And Tomorrow
Calendar words become much easier when they are connected to time markers. These small words help turn a list of vocabulary into real sentences.
- aujourd’hui — today
- demain — tomorrow
- après-demain — the day after tomorrow
- hier — yesterday
- avant-hier — the day before yesterday
- la semaine prochaine — next week
- le mois dernier — last month
- l’année prochaine — next year

| Give the date | Nous sommes le 18 juin. | It is June 18. |
| Ask the day | Quel jour sommes-nous ? | What day is it? |

Pronunciation Notes For Calendar Words
French calendar words are short, but several have sounds that deserve attention. Learners should listen for silent final letters, nasal vowels, and accents such as é and û.
- lundi: the first syllable has a nasal sound. The final i is pronounced.
- mardi: the final i is clear, similar to the ending of lundi.
- mercredi: three syllables are common in careful speech: mer-cre-di.
- août: the spelling looks long, but the word is short in speech.
- juin: this has a nasal vowel; it is not pronounced like English June.
- juillet: the final written t is not normally pronounced.
- février and décembre: the accent é marks a closed e sound.
Memory Aid: French calendar vocabulary works like a set of labeled drawers. Days tell when something happens in the week, months place it in the year, and seasons describe the wider time period.
