I never take a total "off week". I'll usually go to the gym and have fun, or go for an easy jog.

i usually take about 12 days off every 10 weeks or so
Wow, I'd never take 12 whole days off by choice.
I usually take off from lifting for 3-5 days between programs, but that's just lifting. I will continue to do other activities (HIIT, steady-state cardio, prehab and mobility work) if I can. I try to time breaks around visits to family or other travel so that the off days match days I'd miss the gym anyway. It usually works out pretty well.
I try to take a full week off from lifting at least every 8 weeks.. or at the end of a program.
During that time I continue Hiking or xc-skiing, group fitness classes, ballroom dancing and yoga.. and those I take a rest from when I can't go or when there isn't any.
I do make every 4th week a lighter week, though (lighter weights, fewer sets, lysteria, etc.)

It used to be every 8 weeks, especially when I was doing Waterbury high frequency workouts. I'm aiming for 12 weeks now, so I can finish 3 phases of NROL and then take a week.

After each of NROL units I take one to two weeks off. If I can I time to to go along with some sort of project that gets in the way of workouts. Otherwise I go down to the gym/pool and do HIIT and 'mess around' with whatever wt or machine appeals. I think some of these next times I will do Magnificent Mobility and Inside Out.
