Overnights are counted day-by-day for the selected calendar year: holiday blocks supersede the summer schedule, which supersedes the school-year rotation — the same priority Ohio parenting plans use. The 90-overnight line marks Ohio's automatic 10% parenting-time adjustment on the child-support worksheet; “roughly equal” marks the range courts treat as substantially equal time. Default holiday assignments follow common Ohio local-rule schedules — set each to match your plan. Estimates only; your decree controls. R.C. 3109.04; R.C. 3109.051; R.C. Ch. 3119 (2024 tables).
