Count overnights per parent per year using a calendar-based tool — the number you need to calculate Utah child support.
Click a day to assign it: unassigned → P → R → unassigned
Next step: Use your overnight totals in the Utah Child Support Calculator → If both parents have 111+ overnights, the joint custody worksheet applies and support is calculated differently.
The number of overnights each parent has drives both the custody label and the child support calculation. More balanced overnights can change which support worksheet applies and how much is owed.
When a child stays with each parent at least 111 nights per year, Utah generally treats it as joint physical custody and uses the joint-custody child support worksheet.
An overnight is a night the child sleeps in that parent's care. Counting them accurately across the year — including holidays and school breaks — is what determines your custody and support figures.
