1. Duration before something in the FUTURE

We use the FUTURE Perfect Continuous to show that something WILL CONTINUE up until a particular event or time in the future. For” five minutes” “since Friday “and “for two weeks” are both durations which can be used with the Future Perfect Continuous. Notice that this is related to the Present Perfect Continuous; however, the duration does stops at or before a reference point in the future.

Future Continuous vs. Future Perfect Continuous

If you do not include a duration such as "for five minutes," "for two weeks" or "since Friday," many English speakers choose to use the Future Continuous rather than the Future Perfect Continuous. Be careful because this can change the meaning of the sentence. Future Continuous emphasizes interrupted actions, whereas Future Perfect Continuous emphasizes a duration of time before something in the future. Study the next slide to understand the difference.
