Parenting Time Calculator and Custody Schedule Planner

The Parenting Time Calculator and Custody Schedule Planner lets you build a full custody schedule, count overnights, and see each parent's time-sharing percentage for the year. Set your regular weekday and weekend pattern, add holidays and school breaks, and the planner does the math so you do not have to count nights by hand.

Most family courts measure parenting time in overnights, the number of nights a child sleeps at each parent's home over a full year. Roughly 182 to 183 overnights each is about 50/50; 146 is close to 40 percent; 104 is about 28 percent; and 73 is about 20 percent. Because holidays and breaks shift the rotation, a small change in the schedule can move your percentage more than people expect.

Common patterns you can build and compare include week-on week-off, 2-2-3, 2-2-5-5, 3-4-4-3, and every-other-weekend with a midweek visit. You can layer a holiday rotation on top, then see how the final numbers change. This makes it easy to test a proposal before mediation or a hearing instead of guessing.

In many states the number of overnights affects the child support amount, though the exact threshold and formula vary by state. When you have a schedule you like, export a clean, court-ready calendar for the year and run a child support estimate for your state. This is a self-help planner, not legal advice; your final schedule should fit your court's local rules and your child's best interest.

Frequently asked questions

How does the parenting time calculator work?

You set a regular weekday and weekend pattern, add holidays and school breaks, and the planner counts each parent's overnights and turns them into a clear percentage for the full year.

What counts as a 50/50 schedule?

About 182 to 183 overnights for each parent over a 365-night year is roughly 50/50. Week-on week-off, 2-2-3, and 2-2-5-5 schedules are common ways to reach an even split.

Does parenting time affect child support?

In most states, yes. Many guidelines adjust the support amount based on the number of overnights, but the threshold and formula vary by state, so check your state's rule or run a state-specific estimate.

Can I compare two schedules?

Yes. You can build more than one schedule, see the overnight count and percentage for each, and compare them side by side before you commit to a proposal.

Can I bring the calendar to court or mediation?

Yes. You can export a clean calendar for the year that shows the rotation and holiday plan, which is useful for mediation, a parenting plan, or a hearing.

Is the planner free?

Yes. You can build a schedule, count overnights, see the percentage, compare options, and export a calendar for free.
