Every other week. Wednesday @ 5:00pm until Sunday @ 5:00pm..standard holidays, 2 weeks in the summer..works out to about 112 days a year..I gave up some days to get Wednesday-Sunday. I did not want just Fri-Sun..50/50 would have been logistically impossible. I will be 57 miles away from her and where she will attend school. I wanted to be realistic while getting better than the minimum 80 days a year.
