So you are doing something in the future up until a specific point in time. What verb tense would you use for this? Dah da daaaah, the future perfect continuous, of course! It is formed by subject + will + have been + verb in “ing” form.
An example would be “I will have been dancing for hours when the sun rises.” This describes that I will continue dancing until the mentioned point in time, when the sun rises. When the action starts is somewhat ambiguous though. I could have been dancing already, or I’m starting to dance now, or I won’t start to dance until the future, though before the sun rises. Think of it as you have projected yourself into the future, when the sun rises in this case, and you are looking back on all the dancing you have accomplished.
An important thing to note is that future perfect continuous is for action verbs only because it’s describing the duration of an action. For nonaction verbs (to be, to know, etc) you would use the future perfect tense. As a reminder the future perfect tense is formed by subject + will + have + past participle.
By the time I finish writing this blog, I will have been writing blog posts for three hours!
