How to use this calculator
Enter the display range, pattern anchor and A/B letters, one per date. Set the handoff clock time, then add any agreed inclusive-date overrides for Parent A or B.
The pattern repeats before and after its anchor. Each calendar date belongs to the chosen parent from handoff time until the following day's handoff. Contradictory overrides stop calculation so the conflict can be resolved.
A worked example
Starting November 2, 2026, AABBAAA assigns seven daily blocks. Overriding November 7-8 to Parent B gives Parent A three blocks and Parent B four.
Does this suggest or interpret custody arrangements?
No. It displays a pattern and exceptions you already supply. Confirm that the pattern, handoff boundary and overrides match your actual agreement.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Most daily plans allow up to 366 dates; service-budget searches allow 731. Timed intervals have exclusive ends and use browser IANA time-zone rules; nonexistent local times are rejected and repeated times require your choice. Working calendars and policy terms are entered by you. The holiday comparison uses TimeCubby's published country/region coverage. Copy, CSV and print include assumptions; calendar exports appear when dated events exist.
