Child-support guidelines use these counts in their own ways, and many set thresholds of their own: in the US each state’s child support agency publishes its guideline (find your state’s agency); in Great Britain the Child Maintenance Service counts nights a year of shared care.

About the Parenting Time Calculator (Overnights & Percentage Split)
Count each parent’s overnights, days and hours for a year — month by month and in total, with the percentage split — from a custody pattern (alternating weeks, 2-2-3, 2-2-5-5, 3-4-4-3, every other weekend with or without a midweek visit, or your own cycle), with holidays and summer weeks counted. You can also mark individual nights on the calendar for a schedule that follows no pattern.
Tick Compare with a second schedule to see two proposals side by side — for example what giving up a weekend or adding a midweek dinner does to the split. Courts and support guidelines count time in different ways, so all three measures are shown and no threshold is built in: link to your own state’s or country’s guideline below. The free preview shows each parent’s totals for the year and the first rows of each table; a Pro pass unlocks the rest of the tables, the CSV and the printed summary.
How to use it
- Enter the parents’ names and the month and year the count starts.
- Choose the pattern, its first night and who has it, and the handover time; add a midweek visit if there is one.
- Add holidays and summer weeks with the parent who has them — or the parent who has them in even years.
- Select nights on the calendar to give single nights to the other parent; select again to undo.
- Read the split by overnights, days or hours. Tick Compare to count a second schedule; without a pass the tables show their first rows, and a Pro pass unlocks them in full with the CSV and the print.
Examples
2-2-3, first night Monday, January 4, 2027 with Parent A, handovers at 6 pm, January–December 2027
Parent A 182 overnights (49.9%), Parent B 183 (50.1%).
Every other weekend from Friday 6 pm to Sunday 6 pm, January–December 2027
Parent B 52 overnights (14.2%). A Wednesday visit from 5 to 7:30 pm adds 130 hours a year but no overnights.
Every other weekend + midweek visit, two summer weeks and Thanksgiving to Parent B, against 2-2-5-5 with the same holidays (2027)
Parent B 66 overnights against 192: a change of +126 overnights (from 18.1% to 52.6% of the year).
Common uses
- Checking whether a proposed schedule is really close to 50/50 over a year.
- Seeing what giving up a weekend, adding a midweek dinner or moving the summer weeks does to each parent’s share.
- Getting the overnight count a support guideline or a mediator asks for.
How the three counts work
- Overnights: a night counts for whoever has the child at midnight — or at the time you choose, such as 10 pm, when your guideline says “bedtime”.
- Days: a calendar day counts for whoever has the child for more of it; a day split exactly in half counts half to each parent.
- Hours: the clock hours between handovers. Daylight-saving changes are ignored, so every day has 24 hours.
A midweek dinner changes hours but not overnights; a handover at 6 pm instead of after school moves hours from one parent to the other without changing the nights.
Support guidelines use their own rules
Child-support guidelines decide whether and how parenting time changes support, and many use a count of overnights or a percentage. In the US each state sets its own guideline; the Office of Child Support Enforcement lists every state’s agency, where yours publishes its rules. In Great Britain the Child Maintenance Service reduces maintenance when the paying parent has the child overnight for at least 52 nights a year, in steps from 52 to 103, 104 to 155, 156 to 174, and 175 or more nights (GOV.UK: shared care). Use the counts here as the input to your own guideline’s worksheet.
Limitations
- Not legal advice: the court order or written agreement says what the schedule is, and your guideline says how time is counted.
- One 12-month year at a time; holidays given by even and odd years use the year each holiday starts in.
- For a full parenting plan with handover places, swaps, expenses and calendar files, use the Custody Schedule Maker.

Frequently asked questions
What do I get without a pass?
Without a pass, Parenting Time Calculator (Overnights & Percentage Split) shows each parent’s nights, days and hours for the year, with the first rows of the month-by-month table and of the comparison (up to 10). Until you unlock it, the result can’t be downloaded or printed. A Pro, Premium or Ultimate pass, a one-time payment that never renews, unlocks the full result. The pricing page lists the passes and their prices.
How many overnights is 50/50?
Half of the nights in the year: 182 or 183 in a 365-day year. Patterns such as 2-2-3, 2-2-5-5 and alternating weeks give each parent 7 nights in every 14, and holidays move the year’s split a little either way.
Does a dinner visit count as parenting time?
It counts in hours, not in overnights. Which measure matters depends on your court and your support guideline, so the calculator shows both.
Should I count overnights or hours?
Use what your guideline or order uses. Many child-support guidelines count overnights; some courts look at time more broadly. When in doubt, bring both numbers to your lawyer or mediator.
Can I enter a schedule that follows no pattern?
Yes. Pick the pattern closest to it, then select nights on the calendar to give them to the other parent. Marked nights override the pattern and the holidays.
