60/40 Custody Schedule: 4 Ways to Split the Week

A 60/40 custody schedule gives one parent about 60% of overnights (roughly 219 nights a year) and the other about 40% (roughly 146). The common versions are a 4-3 split every week, an extended alternate weekend plus one midweek night, an alternate long weekend plus a weekly Wednesday, and a four-week blend of the two. One thing most template pages skip: no two-week rotation lands on exactly 60/40. Fourteen nights split 60/40 is 8.4 and 5.6, so a fortnight gives you either 8/6 (57/43) or 9/5 (64/36). The four calendars below show the arithmetic for each.

The day columns show where the child sleeps that night. Parent A is the 60% home and Parent B the 40% home. Exchanges are counted per two weeks, and a handoff at school pickup or drop-off counts as an exchange even if the parents never see each other.

The annual figures are the cycle share times 365, rounded: 8 ÷ 14 × 365 = 208.6, so about 209. They assume the rotation runs all year. Holiday and summer schedules shift the real count, sometimes by a lot.

1. The 4-3 every week (8/6)

B picks up Thursday after school and returns Sunday evening, every week. The child is never more than four nights from either parent, and the same nights belong to the same house every week, which makes activities easy to assign.

The trade-off is weekends. In this version B has every Friday and Saturday, so A, the main home, gets the school-night routine and no weekend nights at all. Some families like that division. Plenty don’t. You can move B’s three nights to Monday through Wednesday so A keeps every weekend, but B then never has a weekend. If neither of those suits you, the next two shapes alternate weekends.

2. Extended alternate weekend plus one midweek night (9/5)

In Week 1, B has a long weekend from Thursday pickup to Monday school drop-off, four nights. In Week 2, B has one Wednesday overnight, collecting after school and dropping at school Thursday. That’s five of fourteen nights, or 64/36, which sits a little past 60/40 on the primary-home side.

All four exchanges can happen at school, so the parents don’t have to meet at all. The cost is the gap: after the Week 2 Wednesday, the child goes seven nights without an overnight at B’s. If B lives close, a dinner on one of those days softens it without changing the overnight count.

3. Alternate 5-night block plus a weekly Wednesday (8/6)

B has every Wednesday. In Week 1 that Wednesday runs straight into the weekend, giving a five-night block from Wednesday pickup to Monday drop-off. That’s six of fourteen nights, 57/43, the same split as the 4-3 in a different shape.

This is the every-other-weekend schedule made thicker. It keeps the shape most families already know, alternating weekends with one standing midweek night, and adds enough time to get near 60/40. A same weeknight every week is also what makes the 2-2-5-5 easy to run: Wednesday’s swim class always belongs to B. The longest gap from A is five nights and from B six.

4. The four-week blend (17/11)

If you need to be as close to 60/40 as a repeating calendar allows, alternate the two fortnights above. Run schedule 3’s two weeks (8/6), then schedule 2’s two weeks (9/5). That adds up to 17 of 28 nights at A’s and 11 at B’s: 17 ÷ 28 = 60.7%. Over a year that’s about 222 and 143 nights, within three nights of an exact 219/146.

It’s the most accurate version on paper and the hardest to remember, because the pattern only repeats every four weeks. Run it from a shared calendar, not from memory. Families who pick it usually do so because a number in their agreement or a support worksheet calls for close to 60/40, not because the kids notice a ninth night.

Which one fits

  • School-age kids, homes close together: schedule 3. It looks like a familiar alternating-weekend pattern, and the weekly Wednesday keeps B in the weekday routine.
  • A preschooler: schedule 1. The shortest gaps (no more than four nights from either parent) suit younger kids, provided you sort out the weekend question first.
  • Parents who shouldn’t meet at handoffs: schedule 2. Every exchange can run through school or daycare.
  • An agreement or worksheet that needs a specific number: schedule 4, or one of the others with holiday and summer time used to close the gap.

A 60/40 is often what’s left when a full 50/50 doesn’t work. Maybe one parent’s job can’t cover alternate weekday mornings, or the homes are just far enough apart that a 2-2-3 means a commute every other day. The co-parenting schedule hub compares the 50/50 rotations a 60/40 usually replaces. If the distance is bigger still, the every-other-weekend schedule is the next step down.

Where the overnight count matters

Two places outside your house care about the exact number.

Federal taxes. IRS Publication 504 (loaded October 7, 2026) treats the custodial parent as “the parent with whom the child lived for the greater number of nights during the year.” On any 60/40, that’s the 60% parent by default, whatever the support arrangement says.

Child support. Many state guidelines adjust support for parenting time, and some use overnight thresholds, so a few nights either way can matter. How that works, with every state’s official calculator, is in child support with 50/50 custody.

This is a logistics post, not legal advice. The schedule that binds you is the one in your parenting plan or court order, so have a family-law attorney where you live check any change before you rely on it.

FAQ: 60/40 custody schedules

How many overnights is 60/40? About 219 nights for the 60% parent and 146 for the 40% parent in a 365-day year. In a two-week cycle that’s 8.4 and 5.6 nights, which is why real schedules land at 8/6 or 9/5.

Is 4-3-3-4 a 60/40 schedule? No. A 4-3 week followed by a 3-4 week gives each parent seven nights per fortnight, which is 50/50. Only a 4-3 that repeats the same way every week is 57/43.

Is 60/40 considered joint custody? Joint physical custody is defined by state law, not by a percentage, and states draw the line differently. Ask a family-law attorney in your state.

Can a 60/40 schedule become 50/50 later? Yes, by agreement documented in writing, or by modifying the order. Schedule 3 converts most easily, since adding Week 2’s Thursday to B makes a 7/7 split.
