Parent A
50.0%
7 of 14 overnights per cycle
≈ 183 overnights per year
Parent B
50.0%
7 of 14 overnights per cycle
≈ 183 overnights per year
Courts count overnights, not hours — a dinner visit that ends at 8pm does not change the percentage. If you want the same numbers laid out month by month, run the custody schedule generator, or read the full breakdown of every rotation on the custody schedules hub.

How this is calculated
Percentages are counted in overnights over a full repeating cycle, which is how most courts and state worksheets measure parenting time. Custom patterns are counted over the 14-day cycle you build.
CustodyTrac publishes educational information, not legal advice. Custody and support outcomes depend on facts a calculator cannot see — confirm anything that matters with a family law attorney in your state.
