To introduce a phrase that describes the length of a period of time in French, use time indicators like il y a meaning ago , Ça fait…que, or il y a…que meaning which both mean “it’s been…that”, or the famous French word voilà:
If you are already familiar with prepositions of time in French, here you will learn new time indicators to introduce lengths of time, which tenses they are used with, and common ways of expressing lengths of time in French.
How to say how long ago something happened in French?
Il y a is the French equivalent of “ago.” It indicates that you’re discussing how much time has passed between the moment of speaking and when the action occurred. Like “ago,” il y a is used with past events, but unlike “ago,” the phrase il y a goes before the duration of time, rather than after. Il y a usually comes after the verb, but it can also go at the beginning of a sentence.
Let’s now have a look at a couple of alternatives to il y a.
How to say how much time has passed in French?
Use the time indicators ça fait…que and il y a…que to say how long it’s been since something happened. You should use ça fait…que or il y a…que if you are really focusing on the time that has passed since the action. The simple il y a meaning ago, which we saw above, keeps the focus on when in time the past action occurred. Notice also that ça fait…que and il y a…queare only used at the beginning of a clause.
As you can see above, ça fait…que and il y a…que are preferred when emphasizing the duration of time having passed. However, there are a few different ways to use these time indicators, depending on the tenses you use after que. Let’s take a look.
How to say how much time passed after a past event ended?
To talk about the amount of time that passed after a past event ended, use the expressions ça fait…que and il y a…que with past tenses in French. Depending on when in the past an event happened, you will conjugate the verbs of the expressions ça fait…que and il y a…que differently, as well as the verbs in the following clause.
To emphasize the length of time between a past event and now, conjugate the verbs of the expressions il y a…que and ça fait…que in the present tense, followed by the passé composé in the next clause:
Present Tense
(il y a… que, ça fait…que)
To emphasize the length of time between two past events, when one happened before the other, use the imperfect tense for the verbs in il y a/ça fait…que, and the plus-que-parfait meaning pluperfectin the next clause:
Imperfect Tense
il y avait… que
ça faisait…que
pluperfect
Getting the hang of it? Take a look at a few more examples to fully grasp when to use which past tense:
Imperfect // Pluperfect | Present // Passé Composé |
Ça faisait un an qu’on ne s’était pas vus. Translation: It had been a year since we had last seen each other. | Ça fait un an qu’on ne s’est pas vus. Translation: It has been a year since we last saw each other. |
Il y avait deux mois qu’ils avaient rompu. Translation: It had been two months since they had broken up. | Il y a deux mois qu’ils ont rompu. Translation: It has been two months since they broke up. |
How to talk about how long an event that is still happening has been going on?
To talk about how long an event that is still happening has been going on, use il y a…que and ça fait…que in the present tense, followed by the present tense in the next clause. Here’s the formula:
Present Tense
il y a… que
ça fait…que
present tense
How to talk about the amount of time that will pass before another event?
To talk about the time that will pass before another event, use ça fait…que and il y a…que in the future tense. We use these phrases to talk about the amount of time between a future event and something that will have happened by that future moment. The verb in the following clause can be in the past, present, or a future tense, depending on the context! Here’s the formula:
| Tense in the second clause | Example | Note |
|---|---|---|
past tense | Ça fera deux mois qu’on ne s’est pas vus ! Literally: lit. It will be two months that we did not see each other. | → Here, we focus on how long it will be since our last encounter (which happened two months before). |
present tense | Il y aura deux mois qu’on ne se voit pas ! Translation: It will be two months that we have not seen each other. | → We don’t intend to see each other. (and we have not seen each other for two months.) |
future tense | Il y aura deux mois qu’on ne se sera pas vus ! Translation: It will be two months since we will have seen each other. | → Here, we imply that we will see each other at some point. A future action will happen two months after a point in the future where we see each other. |
How to use ‘voilà … que’ in French?
This indicator of time can be used just like ça fait…que and il y a…que. The tense of the verb following voilà determines whether you’re talking about something that happened, something that is still happening, or something that will happen.
How to talk about approximate lengths of time in French?
When you don’t know an exact duration of time between two events, you can use an approximate length of time using the time indicators you now know. For example, you can use quelques meaning a few or environ meaning about before a length of time, or some of the common expressions below:
une éternité Translation: a lifetime | des lustres Translation: years Literally: (lit. some five year periods) | un (bon) moment Translation: a (long) while |
un bout de temps Translation: a long time | un bail Translation: a long time Literally: (lit. a lease) | une plombe (fam.) Translation: an hour |
