French Time Expressions: Complete Guide to PENDANT, IL Y A, and DEPUIS

One of the most confusing areas of French grammar for English speakers is expressing time. The three expressions pendant, il y a, and depuis all relate to time, but they are used in completely different contexts. Choosing the wrong one can change the meaning of your sentence entirely—or make your French sound unnatural.

This comprehensive guide will explain everything you need to know about pendant, il y a, and depuis: their meanings, when to use each one, how they differ, common mistakes, and plenty of examples. By the end, you will be able to express time in French with confidence and precision.

The Core Difference

Before diving into the details, here is the fundamental distinction between these three expressions:

• PENDANT – Duration (how long something lasted). Focuses on the length of time an action took. Used with past, present, and future tenses.
• IL Y A – Point in the past (how long ago something happened). Focuses on when an event occurred. Used only with past tenses.
• DEPUIS – Starting point (since when / for how long something has been happening). Focuses on an action that began in the past and continues to the present. Used with present tense (for ongoing actions) or past tenses (for completed actions with present relevance).

Quick Comparison:

• J'ai étudié pendant deux heures. – I studied for two hours. (How long? Duration.)
• J'ai étudié il y a deux heures. – I studied two hours ago. (When? Point in the past.)
• J'étudie depuis deux heures. – I have been studying for two hours. (Started two hours ago and still studying.)

1. PENDANT: Expressing Duration

Pendant means "for" or "during" and is used to indicate the duration of an action. It answers the question "How long?"

Key Rule:

Pendant is used with all tenses (past, present, future) to describe how long something lasted, lasts, or will last.

Examples in Past Tense:

• J'ai travaillé pendant trois heures. – I worked for three hours.
• Elle a dormi pendant huit heures. – She slept for eight hours.
• Nous avons voyagé pendant deux semaines. – We traveled for two weeks.
• Il a étudié pendant toute la nuit. – He studied all night (for the whole night).

Examples in Present Tense:

• Je travaille pendant huit heures par jour. – I work for eight hours a day.
• Elle dort pendant la nuit. – She sleeps during the night.

Examples in Future Tense:

• Je vais voyager pendant un mois. – I am going to travel for a month.
• Nous resterons à Paris pendant trois jours. – We will stay in Paris for three days.

With "WHOLE" (Toute / Tout / Toute):

• Pendant toute la journée – For the whole day
• Pendant tout le mois – For the whole month
• Pendant toute l'année – For the whole year

Beginner Tip: Use pendant when you want to say how long something took. Think of it as measuring the length of time an action occupied.

2. IL Y A: Expressing a Point in the Past

Il y a means "ago" and is used to indicate when an event happened in the past. It answers the question "How long ago?"

Key Rule:

Il y a is always followed by a duration and is used only with past tenses (passé composé, imparfait, passé simple). It is never used with the present or future tense.

Structure:

Il y a + duration + past tense verb

Examples:

• Je suis arrivé il y a deux heures. – I arrived two hours ago.
• Elle est partie il y a trois jours. – She left three days ago.
• Nous avons mangé il y a une heure. – We ate an hour ago.
• Il a appelé il y a cinq minutes. – He called five minutes ago.

With Specific Times:

• Je l'ai vu il y a deux mois. – I saw him two months ago.
• Nous sommes allés à Paris il y a un an. – We went to Paris a year ago.
• Elle a commencé à travailler il y a dix ans. – She started working ten years ago.

Beginner Tip: Use il y a when you want to say when something happened. Think of it as pointing back to a specific moment in the past.

3. DEPUIS: Expressing Duration from the Past to the Present

Depuis means "since" or "for" and is used to indicate an action that started in the past and is still continuing in the present. It answers the question "Since when?" or "For how long?" (when the action is still ongoing).

Key Rule:

Depuis is most commonly used with the present tense to describe an action that began in the past and continues now. It can also be used with the passé composé for actions that started in the past and have present relevance.

Structure:

Subject + present tense verb + depuis + duration / point in time

With Duration (for how long):

• J'étudie le français depuis deux ans. – I have been studying French for two years. (I started two years ago and still study.)
• Elle travaille ici depuis cinq mois. – She has been working here for five months.
• Nous habitons dans cette maison depuis dix ans. – We have lived in this house for ten years.

With a Point in Time (since when):

• J'étudie le français depuis 2020. – I have been studying French since 2020.
• Elle travaille ici depuis janvier. – She has been working here since January.
• Nous habitons ici depuis notre mariage. – We have lived here since our wedding.

With NEGATION (to express that something has NOT happened for a period of time):

• Je n'ai pas vu Marie depuis une semaine. – I haven't seen Marie for a week. (The last time I saw her was a week ago.)
• Il n'a pas mangé depuis hier. – He hasn't eaten since yesterday.
• Nous ne sommes pas sortis depuis longtemps. – We haven't gone out for a long time.

Important: DEPUIS with Present Tense (Ongoing Action):

In English, we use the present perfect ("have been doing") for actions that started in the past and continue. In French, this is expressed with the present tense + depuis.

• Je vis ici depuis 2018. – I have lived here since 2018. (I still live here.)
• Il pleut depuis ce matin. – It has been raining since this morning. (It's still raining.)

Beginner Tip: Use depuis when the action started in the past and is still happening now. In English, this often translates to "have been doing" or "has been doing."

4. Comparison Table: When to Use Each

Here is a quick reference guide:

• PENDANT – Meaning: for / during. Focus: Duration (how long). Tenses: Past, Present, Future. Example: J'ai travaillé pendant deux heures. (I worked for two hours.)
• IL Y A – Meaning: ago. Focus: Point in the past (when). Tenses: Past only. Example: J'ai travaillé il y a deux heures. (I worked two hours ago.)
• DEPUIS – Meaning: since / for. Focus: Duration from past to present. Tenses: Present (ongoing action), Past (with negation or actions with present relevance). Example: Je travaille depuis deux heures. (I have been working for two hours.)

• "Pendant = how long" – Think of "pendant" as measuring the length of time.
• "Il y a = how long ago" – Think of "ago" when you see "il y a."
• "Depuis = still happening" – Think of "since" and remember that the action continues.
• "If it's over, use pendant. If it's ongoing, use depuis. If it's a past point, use il y a." – A simple summary rule.

8. How to Practice PENDANT, IL Y A, and DEPUIS

Consistent practice is the key to mastering these expressions. Here are some effective strategies:

• Create flashcards with sentences using each expression.
• Write three sentences about your life using each expression.
• Practice converting sentences: Change a pendant sentence to a depuis sentence and vice versa.
• Read French texts and highlight every instance of pendant, il y a, and depuis.
• Listen to French podcasts or videos and note how these expressions are used in context.

9. Cultural Note: Time Perception in French

The French have a nuanced way of expressing time that reflects their attention to precision and clarity in language.

Precision is Valued:

Using the correct time expression shows that you understand not just the vocabulary but also the temporal logic of the language. It signals linguistic competence.

The French and the Present:

The French often use the present tense more than English speakers do, especially with depuis, because they emphasize the continuity of actions from the past into the present.

Fun Fact:

In French, you can often say Je suis là depuis une heure (I have been here for an hour) while an English speaker might say "I've been here for an hour." The French structure is more direct and economical.

Final Thoughts

Mastering pendant, il y a, and depuis is essential for expressing time accurately in French. Remember the golden rules:

• PENDANT = duration (how long) – Use with any tense.
• IL Y A = ago (when) – Use only with past tenses.
• DEPUIS = since/for (started in the past, continues now) – Use with present tense for ongoing actions.

With consistent practice, these distinctions will become second nature. The more you immerse yourself in French, the more intuitive these temporal expressions will become.
