The indicative future perfect tense in French is used to express actions that will happen and be completed in the future. It also has other applications, such as being used to express probability in the past, talking about historical events and for the subordinate clause in timed events where the subordinate clause happens after or before the main clause and that follows one of the following conjuctions:
quand,
lorsque,
aussitôt que,
