What is a 2-2-3 custody schedule?

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.

How do overnights affect child support?

Many states reduce child support when the non-custodial parent has substantial parenting time. More overnight time means the parent incurs more direct costs, so this worksheet keeps parenting time separate from the support calculation.

What is the most common custody arrangement?

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 parents look for more equal parenting time.

Can custody schedules be modified?

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.

How are holidays handled?

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.

What about long-distance custody?

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.

About the Custody Schedule Calculator

Custody schedules determine how much time each parent spends with their children after separation or divorce. The number of overnights each parent has can affect child-support worksheets and the day-to-day logistics of co-parenting.

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 a custody schedule into an annual parenting-time percentage by dividing overnights by 365. It also shows preset common schedules for quick comparison.

When This Page Helps

Accurate custody-time percentages are useful for comparing schedules and discussing support scenarios, but they are only one part of a parenting plan. The worksheet is most helpful when you want to compare arrangements without treating one schedule as a legal verdict.

How to Use the Inputs

Select a preset custody schedule or choose custom.
For custom, enter the number of overnights per year for Parent A.
The calculator automatically computes Parent B’s overnights.
Review the percentage split and annual/monthly breakdown.
Compare different schedules to find what works best.

Formula used

Parent A Time % = (Parent A Overnights / 365) × 100
Parent B Time % = 100 − Parent A %
Parent B Overnights = 365 − Parent A Overnights

Example Calculation

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.

Tips & Best Practices

The 2-2-3 schedule provides a true 50/50 split over a two-week cycle.
Every-other-weekend gives the non-custodial parent only about 14% time (52 overnights).
Adding a mid-week overnight increases non-custodial time from 14% to about 28%.
Holiday and vacation schedules should be factored into the annual total.
Consider the child’s school schedule, activities, and proximity of parents’ homes.
Document the actual schedule followed, not just the court order, for modification requests.

Common Custody Schedule Comparison

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.

Age-Appropriate Scheduling

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.

Making Schedules Work

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.

Sources & Methodology

Last updated: March 28, 2026

Methodology

This worksheet converts a schedule into an annual parenting-time percentage by counting overnights for each parent. It then layers in simple holiday and summer adjustments so users can compare common arrangements without pretending the page knows the local custody order.

The result is a planning worksheet, not a custody ruling. Actual parenting plans can include exchange timing, school-week rules, travel distance, holiday rotations, and court-specific conditions that are not fully captured by a raw overnight count.
