How are overnights counted in Ohio?

Ohio courts measure parenting time in overnights per year. This calculator converts common schedules — such as every other weekend, 2-2-3, or week-on/week-off — into each parent's annual overnight count and percentage.

What is the 90-overnight rule in Ohio?

When the parent who pays child support has at least 90 overnights per year in a shared-parenting arrangement, Ohio's guidelines allow a parenting-time adjustment that can reduce the support obligation.

How many overnights is a 50/50 schedule?

Equal schedules like 5-2-2-5, 2-2-3, and week-on/week-off generally give each parent about 182 overnights per year, or roughly half the year.

Does this calculator set my parenting schedule?

No. It is an estimate to help you plan. The final parenting schedule is decided by your parenting plan and the court, and actual overnights vary with holidays and breaks.

Ohio Parenting Time Calculator

Turn an Ohio custody schedule into real numbers. Choose a common parenting schedule — such as every other weekend, 2-2-3, or week-on/week-off — and see each parent's annual overnights, their share of parenting time, and whether the schedule reaches the 90-overnight threshold that can affect child support. This tool is an estimate; the court decides the final schedule.

Why Overnights Matter in Ohio

In Ohio, the number of overnights each parent has is more than a scheduling detail — it shapes both your parenting plan and your child support. Courts describe parenting time in overnights per year, so translating a schedule into a clear annual number helps both parents negotiate from the same facts.

The 90-Overnight Threshold

The 90-overnight mark is an important line. When the parent who pays support has at least 90 overnights a year, Ohio's child support guidelines allow a parenting-time adjustment that can reduce the obligation. Equal or near-equal schedules — 5-2-2-5, 2-2-3, and week-on/week-off — generally land each parent near 182 overnights, or roughly half the year.

Common Ohio Parenting Schedules

Every other weekend — about 52 overnights a year for the non-residential parent.
Every other weekend plus a weeknight — about 104 overnights a year.
2-2-3, 5-2-2-5, or week-on/week-off — roughly equal, about 182 overnights each.
