Future Perfect Continuous Infographic 1: Just like with the other perfect continuous tenses (and the future perfect simple), we can use the future perfect continuous to say 'how long' for an action that continues up to another point in the future. The second point can be a time or another action. Generally, we need 'for + length of time' and if we use 'when' or 'by the time', we usually use the present simple. In the same way as with the future perfect simple, we often use the future perfect continuous because we like easy numbers. It's also possible to use the present perfect continuous, but then we get a more complicated number. 2: We can use the future perfect continuous, like the other perfect continuous tenses, to talk about something that finishes just before another time or action (in this case, in the future). It's often used because there will be a result at the second point in the future. (Again, if we use 'when' we usually need the present simple.)
