Coparenting Calendar Builder
"Whose weekend is it" starts a fight every single month. Holiday fights peak in November: family mediators warn that emergency holiday motions filed in late November can cost thousands of dollars in legal fees, and the court may not rule before the holiday passes. Their October rule is simple: parents who settle the holiday schedule in October have smooth celebrations. Paid custody trackers sell on Etsy with many reviews, showing parents will pay for exactly this clarity. This skill builds the calendar once and hands both parents the same file.
Coparenting Calendar Builder runs the whole setup:
1. Pattern and dates in
You pick the schedule (every_other_week, 3_4, 2_2_3, or 5_2), the start date, and both parents' names.
2. Full year calendar out
The script generates every day of the year and writes a real calendar file you both import into your phones, with one event per custody block.
3. Exact split percentages
Day counts and percentages per parent, to one decimal, for your records or your file.
4. Holiday rotation
Thanksgiving and Christmas alternate by odd and even year, with the assignments spelled out for the next four years, so November never surprises you again.
5. Shared expense ledger
A clean ledger template tracks kid expenses, who paid, and the split, ending the other monthly argument.
What makes this different:
- It makes a real file. A naive approach describes a schedule in chat. This writes an importable calendar both parents actually use.
- It does the holiday math. The flip flop rotation is encoded, not left to memory, with four years visible at once.
- It measures fairness. Exact percentages replace the feeling that the split is uneven with numbers both sides can see.
How It Works
- Agree on the pattern: pick the schedule that fits your family
- Set the start date: the first day parent A has the kids
- Run the builder: one command generates the year
- Import everywhere: both parents add the calendar file to their phones
- Review the split: check the percentages match your agreement
- Lock the holidays: confirm the rotation before November
Who It's For
Divorced or separated parents sharing custody who want one source of truth instead of monthly negotiations. Works for 50/50 arrangements and uneven splits, and for grandparents or caregivers as the two parties.
