Each preset maps to an illustrative count of annual overnights for Parent B. Parent A receives the remainder of a 365-night year. You may add “extra” Parent B overnights to mimic holidays, school breaks, or make-up time. Custom mode lets you type Parent B overnights directly before extras. Percentages round to one decimal for display.
Pickup windows, travel notice, right of first refusal, communication, and decision-making authority belong in a full parenting plan—not in this overnight tally.
