To refer to events that will occur in the future, English uses the word “will.”

I will go to the store.

We'll do it later.

There is another future tense in English that's used to indicate events that will be completed at some point in the future. In English, it is known as the future perfect because it is an event that will be completely finished, or perfected. Here are some examples:

By six o'clock, I will have gone to the store.

When the dessert has finished baking, we will have finished supper.

In French you have three forms of the future tense: le futur proche, le futur simple, and le futur antérieur.
