Parenting Time Split (Co-parenting) Calculator

Plan your co-parenting schedule with this comprehensive parenting time calculator. Enter weekday, weekend, holiday, and summer time distributions to see exact custody percentages, overnight counts, and recommended scheduling arrangements for your family.

Number of weekdays (Mon-Fri) child spends with Parent 1

Number of weekends per month child spends with Parent 1 (1 weekend = Sat-Sun)

Approximate school days per year (typically 180)

Number of major holidays (Christmas, Thanksgiving, etc.) with Parent 1

Number of full summer vacation weeks with Parent 1

Distance between the two parents' homes (affects travel and exchange logistics)

Total Days = (Weekdays × 52) + (Weekends × 2 × 12) + Holidays + Summer Days
Parent 1 Days + Parent 2 Days = 365
Parenting Percentage = (Days with Parent ÷ 365) × 100%
Example: Parent 1 gets 3 weekdays/week, 2 weekends/month, 5 holidays/year, 4 summer weeks → 226 days/year (61.9%), Parent 2 gets 139 days/year (38.1%) → Substantial Parenting Time

What is the standard parenting time split in most states?

Most states default to a standard possession schedule when parents live within 100 miles: every other weekend (Fri-Sun), one midweek evening, alternating holidays, and extended summer time (4-6 weeks). This typically results in approximately 80/20 or 70/30 splits. Many states now encourage shared parenting (50/50) when both parents are willing and capable.

How does parenting time affect child support?

Child support is typically calculated using each parent's income and the percentage of overnight time. In many states, if the non-custodial parent has more than 35% parenting time (about 128+ overnights), a shared parenting adjustment applies that can significantly reduce support obligations. Some states use a 50/50 threshold for equal parenting time adjustments. Always consult your state's specific guidelines.

What parenting schedule works best for school-age children?

For school-age children (5-12), popular schedules include: Alternate weekends plus one midweek dinner/overnight, 2-2-3 schedule (2 days with each parent, then 3), Week-on/Week-off (better for older kids), and extended summer time. Consistency around school routines is crucial. Younger children need more frequent transitions; teenagers often prefer fewer transitions with more flexibility.

How should holidays be divided in a parenting plan?

A good holiday schedule alternates major holidays yearly: Year A: Parent 1 gets Thanksgiving and Christmas Eve, Parent 2 gets Christmas Day and New Year's. Year B reverses it. Include MLK Day, Spring Break, Easter, 4th of July, Labor Day, Halloween, and each parent's birthday/father's/mother's day. Define holiday periods (e.g., Christmas break split in half). Give 30-60 days' notice for holiday preferences.
