Free custody schedule calculator. Compute parenting time split as overnights divided by 365 for common custody arrangements like 50/50 and 80/20.
Custody schedules determine how much time each parent spends with their children after separation or divorce. The number of overnights each parent has directly affects child support calculations in most states and impacts the children's daily routines.
Common custody arrangements include the 2-2-3 rotation (alternating 50/50), every-other-weekend (approximately 80/20), and the 5-2 schedule. Each arrangement has different implications for school nights, travel logistics, and parenting consistency.
This calculator converts any custody schedule into a percentage of time by dividing overnights per year by 365 days. It also shows preset common schedules for quick comparison.

Accurate custody time percentages are essential for child support calculations and custody negotiations. Many parents do not realize how different schedules translate to actual percentages, which can significantly affect support obligations. Instant recalculation as you change inputs lets you model multiple scenarios quickly, giving you the data foundation needed for well-informed legal and financial decisions.
Parent A Time % = (Parent A Overnights / 365) × 100 Parent B Time % = 100 − Parent A % Parent B Overnights = 365 − Parent A Overnights
Result: Parent A: 49.9% | Parent B: 50.1%
With 182 overnights per year, Parent A has 49.9% of parenting time (182/365). Parent B has 183 overnights or 50.1%. This is essentially a 50/50 split typical of alternating week schedules.
The alternating weeks schedule (50/50) works well when parents live close together and communicate effectively. The 2-2-5-5 schedule reduces transitions. Every-other-weekend (EOW) is simpler but provides less balance. EOW plus midweek dinner is a common compromise.
Infants and toddlers benefit from more frequent, shorter visits to maintain attachment. School-age children can handle longer stretches. Teenagers may have input through their preferences, which courts increasingly consider.
Successful co-parenting schedules prioritize consistency and the child's needs. Use shared calendars, communication apps, and clear handoff protocols. Build in flexibility for special events while maintaining the overall structure.
In a 2-2-3 schedule, children alternate between parents: 2 days with Parent A, 2 days with Parent B, then 3 days with Parent A. The following week reverses. This creates a true 50/50 split over each 14-day cycle.
Many states reduce child support when the non-custodial parent has more than a threshold number of overnights (often 90-110 per year). More overnight time means the parent incurs more direct costs, offsetting the need for transfer payments.
Every-other-weekend plus one evening per week is still common, giving the non-custodial parent about 80-90 overnights (22-25%). However, 50/50 arrangements have become increasingly popular as courts recognize benefits of equal parenting time.
Yes, either parent can request modification by showing a material change in circumstances. Common reasons include relocation, changes in work schedule, the child's changing needs as they age, or one parent's failure to follow the current schedule.
Courts typically alternate major holidays annually (Thanksgiving with one parent in odd years, the other in even years). Some families split the holiday itself. Summer vacation is usually divided, with each parent getting extended blocks of time.
When parents live far apart, the non-custodial parent typically gets extended time during school breaks and summer. Transportation costs may be shared. Virtual visitation (video calls) supplements in-person time.
