The phrase parenting time is referred to as the amount of time the non-custodial parent is aloud to spend with their child. When you went to court the specifics should have been outlined by your attorney. If you have a 51/49 split you probably have a set number of days per month you are allowed to have your child. I would guess the other parent probably has your child 2-3 extra days out of the month.

The time in school is irrelevant for both parties.
