Groundhog Day Loop: "A plot in which the character is caught in a time loop, doomed to repeat a period of time"

Groundhog Peggy Sue: "in which a character is forced to re-live a significant portion of his life over and over again, always looping back to a certain point "

So, it's The Same but More Specific: "Groundhog Day Loop, but looooong". And, of course, overlapping examples.
