Week On Week Off Custody Schedule

A 50/50 schedule with a single exchange per week. The fewest transitions of any equal rotation, which is why courts often pair it with a midweek dinner or call in the written order. Over the two-week cycle each parent has 7 and 7 overnights — roughly 50% and 50% of the year before holiday and summer blocks are added.

This counts the base rotation only. Holiday, school-break and summer blocks in a real order move the total — often by a week or more — and schedules are subject to court approval.

Courts retain discretion — guideline results can be adjusted or deviated from. This is the published guideline math, not a prediction of your order.

🎓 Understand this tool

What it is

A parenting-time planner that turns a named rotation into a real calendar and counts the overnights it produces. The overnight count is the figure support worksheets ask for, so this is the bridge between how a family actually lives and how a guideline is calculated.

How it works

Each rotation is a repeating two-week cycle of nights, anchored to Monday so the pattern reads the same whoever opens it. The planner expands that cycle across the year and counts which parent each night belongs to. Overnights, not daytime hours, are what guidelines key on, because a night is unambiguous and provable from a calendar. Exchanges are counted too, because the practical difference between the even rotations is not the split — they are all close to 182 nights each — but how often a child changes homes, which ranges from about one handover a week to nearly three.

Getting the most from it

  1. Pick the rotation closest to what you are discussing. The summaries describe how each one feels week to week, not just how it divides.
  2. Set which parent starts the cycle. On alternating schedules this changes who has which weekend, and it matters to a real family.
  3. Read the overnight count. That is the number a support guideline uses in states that adjust for parenting time.
  4. Carry the count into your state’s child support page, or export the calendar and print it to talk through.

Reading your result

The overnight percentage describes the base rotation. A real order almost always adds holiday, school-break and summer blocks on top, which can move the annual total by a week or more in either direction. Treat the figure as the starting shape of a schedule and expect the final number to differ once the exceptions are written in.

What it can't tell you

This cannot tell you what schedule suits your child, what a court in your county tends to approve, or how to handle distance, school runs, or shift work. It does not draft a parenting plan and is not a substitute for one. Schedules are subject to court approval, and a family lawyer in your state is the person to ask about yours.

Frequently asked questions

Child support guidelines that account for parenting time almost always count overnights rather than hours, because an overnight is unambiguous and easy to prove from a calendar. That is why this planner counts nights: it produces the number a support worksheet actually asks for.
