A coordinated planner for holidays between two households — split schedules, new traditions, low-conflict communication, and step-family integration that actually works.
Which days, which years, whose turn – reopened from scratch every season.

Each household tries to out‑do the other, and the children end up refereeing.
The changeover is the tense part of the day, and the tension lands on the children.
