The future perfect continuous tense is used to describe an action that will have been ongoing for a certain period of time by a specific point in the future. It’s ideal for emphasizing the duration of an activity.
How to Form the Future Perfect Continuous
Use “will have been” followed by the verb with “-ing” (present participle).
Examples:

- She will have been studying for hours by the time the exam starts.
- They will have been traveling for a week by the time they reach their destination.

- I will not (won’t) have been sleeping for long when the alarm goes off.
- He won’t have been practicing enough to win the competition.
- They will not have been working on the project for very long.

To form a question, place “will” before the subject, followed by “have been” and the verb with “-ing.”
