In the real world it is 29.503 days for the full phase ( Full moon to Full Moon again ).

Now in Season 3 Episode 8 Apple Family Reunion, Granny Smith mention that it's been 100 moons since the last one.

In real world terms that would be 29.503 x 100 moons divided by 365 1/4 days a year = 8.077 Years.

Though as they have said " A moon unit " has "no human equivalent."though I would have to say it's close.
