An overnight is typically a night the child sleeps at a parent's residence. Counting overnights is the backbone of parenting-time percentages and many support-related worksheets.
Rules of thumb
- Count the calendar night, not the pickup hour, unless your order defines otherwise.
- Late evening exchanges still usually count as an overnight for the receiving parent if the child sleeps there.
- Track a defined range (e.g., school year) then recompute when summer or holidays apply.
Common mistakes
- Double-counting exchange days for both parents
- Using weekdays only and forgetting weekends
- Ignoring multi-week summer blocks that shift annual %
