Parenting time (sometimes called visitation or custodial time) is the calendar of days and nights a child spends with each parent when parents live apart. Courts, mediators, and parents usually measure it in overnights because overnight counts are objective and easy to annualize.
A parenting-time percentage answers: of all overnights in a year (or sample window), what share belongs to Parent A vs Parent B? That percentage shows up in parenting plans, settlement talks, and—depending on state—child support worksheets.
Overnights vs daytime hours
Daytime hours matter for school pickups and activities, but most formal calculations use the night the child sleeps in a parent's home. If a child is with Parent A from Friday afternoon through Monday morning, that typically counts as three Parent A overnights (Fri, Sat, Sun).
Why the number matters
- Clarity: Both parents see the same math instead of arguing about “who has them more.”
- Planning: Holidays, summers, and school years can be layered onto a base schedule.
- Support contexts: Some states adjust guidelines using overnight counts—always verify with a licensed professional in your state.
