If I'm asked in child care deductions how many "weeks" an overnight camp was, and the camp was less than one week, should i say 1 or zero? And what if it is 10 nights?

If it is a day camp > enter it as a regular daycare expense > do not enter the weeks or days

If it is an overnight camp where the child spends the night outside home or a boarding school > enter it by weeks, 1-week minimum. 

I hope this was helpful
