Your one-period snapshot
Compare one period
Use the same counting unit throughout. The result updates as you type and stays on this device.
Worked 14-day example
Period: 14 overnights. Planned: 7. Missed: 1. Completed make-up: 1. Actual = 7 − 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 UK
Three things need to stay separate in a record. What the arrangement says, what actually happened, and the file that shows it. Blur them together and a reader has to take your word for it. Keep them apart and the record speaks for itself.
The UK is not one family-law system. England and Wales, Scotland and Northern Ireland each have their own rules, forms and vocabulary. Use the words that appear in your own order or agreement rather than a term borrowed from somewhere else.
Keep the complete source file, not a crop of it. Write events in the order they happened, and say plainly where something is missing or unclear. A family solicitor can work with a record like that. They cannot work with a reconstruction.
Which part of the UK your case is in
England and Wales, Scotland and Northern Ireland each have their own family courts and rules. Say which one your case is in, and use the same words your order or plan uses. Only mention addresses or schools when they help explain what happened. Before you treat a private timeline as a court document, check the rules with a solicitor.
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.
Before you share your record
Everything above is about keeping your own record. Before you show any of it to someone else, a few extra steps help.
Work from a copy and leave the original untouched. Take out any private details the reader does not need.
Check that every important sentence links back to a date or a source. If one does not, rewrite the sentence rather than filling the gap with a guess.
Family law is different in England and Wales, Scotland and Northern Ireland. Make clear which one your case is in, and ask a family solicitor what the court rules let you share.
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 cover Scotland and Northern Ireland too?
No. England and Wales, Scotland and Northern Ireland have separate family-law systems, forms and terms. Use this page to keep your own record in order, and get advice from someone who works in your part of the UK.
