Do not mix different definitions
For federal tax purposes, the IRS generally uses the greater number of nights, with detailed rules and exceptions. See IRS Publication 504. Do not assume a calendar label or custody agreement settles every tax question.
Use names for everyday logistics
“Mom collects at 3:15” or “Jordan has Friday overnight” is usually clearer in a calendar than a legal label. Keep the practical plan readable while preserving the relevant formal documents separately.
Check what the app is counting
CoFam shows recorded schedule information. It does not determine tax eligibility, calculate child support, or decide a legal custody category. Use the required records and professional guidance for those purposes.
Is a CoFam percentage a tax determination?
No. Tax rules have their own definitions and requirements.
What should we put in the calendar?
The responsible person, date, time, and handoff details, using labels your family understands.
