Formula Used
Overnight Share (%) = Parent Overnights ÷ Total Overnights × 100
Documented Contact Hours = (Overnights × 24) + (Weekday Visits × Hours per Visit) + Holiday Hours + (Vacation Days × 24)
Contact Share (%) = Parent Contact Hours ÷ Total Contact Hours × 100
Average Weekly Overnights = Parent Overnights ÷ (Period Days ÷ 7)
Projected Yearly Overnights = Parent Overnights ÷ Period Days × 365
Travel Hours = Exchanges × Average Travel Minutes ÷ 60
Weighted Share (%) = (Overnight Share × 0.70) + (Contact Share × 0.30)
Balance Index = 100 − |Overnight Share − 50| × 2
The balance index is a planning measure for internal review. It is not a legal standard.

Frequently Asked Questions
1. What does the overnight share measure?
It shows each parent's percentage of total recorded overnights during the selected period. This is often the clearest starting point for schedule comparisons.
2. Why are contact hours different from overnights?
Contact hours include visits, holidays, and vacation time in addition to overnights. This gives a broader picture of involvement across shorter visits and special periods.
3. Can I use this for weekly or yearly reviews?
Yes. Enter any period length you need. The calculator scales averages and yearly projections from the period you choose.
4. What happens if overnights do not match the period?
The schedule status line flags missing or excess overnights. That helps you catch gaps, overlaps, or logging mistakes before saving reports.
5. Is the weighted share a legal formula?
No. It is a planning metric that blends overnights and contact hours. It can support discussions, but local rules may use different standards.
6. Why track exchange travel time?
Travel time highlights the practical load around exchanges. It helps families compare schedule efficiency and understand how transitions affect routines.
7. Can the report be saved for mediation notes?
Yes. Use the CSV download for spreadsheet review and the PDF download for printable summaries, meetings, and organized case records.
8. Does this calculator replace legal advice?
No. It is a schedule tracking and planning tool. Court calculations, parenting plans, and local legal definitions can differ.
