Worked 14-day example
Period: 14 overnights. Planned: 7. Missed: 1. Completed make-up: 1. Actual = 7 โ 1 + 1 = 7 overnights. Planned share = 50%. Actual share = 50%. Variance = 0. Link the missed and make-up nights to their dated records.
Hours example
For a 14-day hourly period, enter 336 total hours. Use hours for every other field. Do not mix an overnight value into an hourly calculation.
How to read this in the United States
Custody questions rarely have one US-wide answer. State law differs, and county rules differ inside a single state. Start with the order or parenting plan that actually applies to you.
Record each event with the date it happened and the date you wrote it down. Keep the whole message thread, bill or calendar item rather than a crop of it. A screenshot should never be your only copy.
A reader should be able to see what happened, when you recorded it and what changed afterwards. Take the legal questions to a family-law attorney licensed in your state.
State-and-county checklist for a US review
Put the state, county, and court on the cover sheet. Quote the custody order or parenting plan. Keep court notices and portal files in their first form. Flag a move, school line, or issue between states for legal review. Do not guess which state rule controls.
Choose a unit before entering values
Overnights and hours answer different organizational questions. Use one unit for every value in a calculation and state the counting rule in the record. Do not convert between units by changing the toggle. The tool preserves the numbers and changes only the unit label. Courts, agencies, agreements, and support systems may count time differently.
Define the period and planned time
A fourteen-day schedule has fourteen overnights, while a fourteen-day hourly review has 336 hours. Planned time is the amount assigned in the schedule for the chosen unit and period. Keep the schedule or agreement as a linked source.
Subtract missed time and add completed make-up time
Missed time is part of the planned allocation that did not occur. Make-up time should be counted only when it occurred within the selected period. A proposal is not completed time. The calculator prevents missed time from exceeding planned time and prevents planned or actual time from exceeding the period.
Read share and variance together
Planned share is planned divided by the period total. Actual share uses calculated actual time. Variance is actual minus planned: a negative figure means actual time was lower in that period. A positive figure means it was higher. The figures describe inputs, not why a difference occurred.
Link every adjustment to the chronology
A percentage without its rows is difficult to audit. Link missed units to a missed-handover entry and make-up units to the completed event. Record later corrections transparently, then rerun the calculation and date the revised summary. It isn't useful to detach the summary from those source rows.
Keep legal and administrative calculations separate
This aid does not decide custody allocation, child support, entitlement, compliance, or what a court will accept. Definitions can vary by US state, UK nation, Australian state or territory, Canadian province or territory, and other systems. Use the terms and method needed by the relevant document or qualified local adviser.
A US review note
Compare planned and actual parenting time for one period using overnights or hours, including missed and completed make-up time. Sharing any of it in the United States takes a few more steps.
Take one question at a time. Attach the current order, a short timeline and the source files that carry the point. Keep the rest of the record safe in case it is needed later.
Check local rules before you file or send anything. Ask a family-law attorney licensed in your state or use the court's own help pages. Rules for hidden details, proof, exhibits, and due dates vary.
Put the state and county on the review note. Use the terms from the local order. A rule or label from one state may not apply in another.
Can I use decimals?
Yes. Hours and other units may use decimals. Results are rounded to two decimal places.
What if missed time exceeds planned time?
The calculator rejects that input. Check the period and records before calculating.
Does make-up time erase a missed event?
No. Keep both dated records. Make-up time changes the period arithmetic, not the history.
Does this calculate child support or a court result?
No. It is solely a record-organizing aid and does not apply local legal formulas.
Does this apply in every state?
No. Custody law, court process and terms differ by state and often by county. Use the page as a records method and confirm legal questions locally.
