Overview

Welcome to your guide on French months! Learning the months is like unlocking a calendar for your new life in French. Whether you are planning a trip to the Eiffel Tower or booking a doctor's appointment, you need these words. In French, months are surprisingly similar to English. This is because both languages share Latin roots. However, there are a few sneaky rules you need to master. First, French months are never capitalized unless they start a sentence. Second, they are all masculine. Third, we use specific prepositions to say "in" a certain month. Think of this as the foundation for your social life in France. You will use these words to talk about your birthday, holidays, and deadlines. Let's dive in and get you calendar-ready!

How This Grammar Works

French months function as masculine nouns. Unlike English, where we always capitalize "January" or "March," French keeps them lowercase. It feels a bit strange at first, but you will get used to it. To say "in [Month]," we primarily use the preposition en. For example, en janvier means "in January." Another common way is to say au mois de. This literally means "in the month of." It sounds a bit more formal or precise. You might hear a news anchor or a boss use it. For daily life, en is your best friend. It is short, quick, and easy to remember. If the month starts with a vowel, like avril or octobre, the preposition en flows right into it. This creates a smooth sound that French speakers love.

Formation Pattern

  1. 1To use months correctly, follow these simple steps:
  2. 2Memorize the twelve months: janvier, février, mars, avril, mai, juin, juillet, août, septembre, octobre, novembre, décembre.
  3. 3To say "in [Month]", simply put en before the word. Example: en mai.
  4. 4If you want to be fancy, use au mois de. Example: au mois de mai.
  5. 5If the month starts with a vowel and you use au mois de, change de to d'. Example: au mois d'avril.
  6. 6Never add le before a month unless you are including a specific date number. Example: en mars (in March) vs. le 12 mars (on March 12th).

When To Use It

Use this grammar when you are talking about general timeframes. Imagine you are in a job interview. Your future boss asks when you can start. You would say, Je commence en octobre. It sounds professional and clear. Or, imagine you are meeting a new friend at a café. You want to tell them when your birthday is. You would say, Mon anniversaire est en juillet. It is also essential for travel. If you are booking a hotel in Nice, you might say, Je viens en août. In these scenarios, the month provides the context without needing a specific day. It is like a wide-lens camera shot of your schedule. You use it for seasons, recurring events, and general plans. Even when talking about weather, you might say, Il pleut souvent en novembre. It sets the stage for your sentence.

When Not To Use It

There is one major trap to avoid: specific dates. If you have a number, the rules change. You do not use en with a full date. Instead, you use le. For example, you say en avril, but you must say le 15 avril. Think of le as a laser pointer for a specific day. If you use en with a number, it sounds like you are trapped in a grammar glitch. Also, do not use dans to mean "in a month" in the sense of a calendar position. Dans usually implies "inside" or "in [amount of time] from now." If you want to say "I'm going in June," stick to en juin. Using dans here is a classic mistake that makes you sound like a literal translator rather than a French speaker.

Common Mistakes

Yes, even native speakers mess this up sometimes, but usually just with spelling! The biggest mistake for English speakers is capitalization. Writing Janvier with a big 'J' is a dead giveaway that you are thinking in English. Keep it small: janvier. Another common error is using the wrong preposition. Some people try to say à janvier or dans janvier. Remember: it is always en. Think of en as the only key that fits the month lock. Also, watch out for the pronunciation of août. Many people try to pronounce every letter. In reality, most French people just say "oot" (like the end of "boot"). If you over-pronounce it, you might get some confused looks at the bakery!

Contrast With Similar Patterns

Let's compare months to seasons. While most seasons also use en (like en été or en hiver), Spring is the rebel. We say au printemps. Months are much more consistent than seasons because they all take en. Compared to English, the lack of capitalization is the biggest hurdle. In English, months are "Proper Nouns." In French, they are treated more like common nouns. Also, English uses "on" for dates and "in" for months. French uses le for dates and en for months. It is a one-to-one swap, but the words are different. Think of it like a grammar traffic light: en means go for months, le means go for dates.
