Yes, you end up with 21 contiguous days off, but 14 of those are days you already had off. (And if you're on one of the CC schedules, you may end up with only 15 contiguous days off, but the number of workdays removed from the schedule is still 7.)

So 26 work weeks, minus two weeks of vacation, is 24 work weeks.
