60/40 Custody Schedule: Patterns, Examples and How It Works
A 60/40 custody schedule gives one parent about four nights a week and the other about three. Counted exactly against a 365-night year, that is 219 nights to 146. Counted as a repeating four-and-three week, it is 209 nights to 156 — 8 overnights against 6 in every fortnight, which is really 57/43. Both arrangements are called 60/40, and in practice families build the split one of two ways: a fixed weekly 4-3 pattern, or an extended weekend that stretches one parent's weekend at both ends.
This guide is general information, not legal advice. Custody rules differ by state and country; check with a family-law professional for your situation.
The two numbers behind "60/40"
Almost every argument about a 60/40 schedule starts with two people using the same phrase for slightly different counts. It is worth settling which one your plan means before you write it down, because the gap is about eleven nights a year — enough to matter where overnights drive money.
| How it is counted | Majority parent | Other parent | Actual ratio |
|---|---|---|---|
| Literal 60% of a 365-night year | 219 nights | 146 nights | 60 / 40 |
| A repeating 4-night / 3-night week | 209 nights | 156 nights | 57 / 43 |
| Per fortnight, on that weekly pattern | 8 overnights | 6 overnights | 57 / 43 |
The weekly version is the one most families actually live, because it repeats cleanly and nobody has to consult a calendar to know whose Tuesday it is. The literal 219/146 version shows up in plans that count time in blocks — a longer holiday stretch, a summer swap — rather than in a fixed weekly rhythm. If your order says "approximately 60/40" and your week is 4-3, you are on 57/43 and that is normal.
For context on how common near-equal splits have become: in our custody-split study of 804 separated parents (April–July 2026), 42% chose an equal 50/50 arrangement, and of the 665 schedule choices in the 2026 data 46% were custom, while among the 357 families who picked a named schedule 36% were weekend-based and 23% alternating weeks. A 60/40 is what a lot of the remainder looks like in practice. The full breakdown is in our survey of the most common custody schedules and the underlying custody split statistics.
Two ways to build a 60/40, side by side
SplitDay has a full guide for each of the two patterns that land on 60/40. They produce a similar night count and feel completely different to live in, mostly because of who holds the weekend and where the handoffs happen.
| Pattern | Who gets the weekends | Exchanges per week | Best for | Guide |
|---|---|---|---|---|
| 4-3 weekly pattern | The 40% parent — every Friday to Sunday | 2 (Thursday or Friday, then Monday) | Two homes near the same school; a majority parent who can run the school week | The 4-3 pattern |
| Extended weekend | The 40% parent — every Friday after school through Monday morning | 2, and both can happen at the school gate | Co-parents who want to avoid doorstep handoffs; one home clearly set up for weekdays | The extended weekend |
A 4-3 fortnight, night by night
The 4-3 pattern runs on a seven-day cycle, so both weeks are identical — that is the entire point of it. Parent A holds the school nights, Monday through Thursday; Parent B has every Friday, Saturday and Sunday. Over fourteen nights that is 8 to 6.
| Parent | W1 Mon | W1 Tue | W1 Wed | W1 Thu | W1 Fri | W1 Sat | W1 Sun | W2 Mon | W2 Tue | W2 Wed | W2 Thu | W2 Fri | W2 Sat | W2 Sun |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Parent A (60%) | ● | ● | ● | ● | · | · | · | ● | ● | ● | ● | · | · | · |
| Parent B (40%) | · | · | · | · | ● | ● | ● | · | · | · | · | ● | ● | ● |
Two handoffs a week, on the same two days, forever. If your family would rather the majority parent keep the weekends, you flip the block — Friday through Monday becomes the four-night side — and the counts stay the same.
An extended-weekend fortnight, night by night
The extended weekend moves the block edge rather than the number of nights. Its signature version starts at Friday pickup from school and ends at Monday drop-off, which gives the weekend parent three nights — Friday, Saturday, Sunday — and leaves Monday to Thursday, all four school nights, with the weekday-base parent.
| Parent | W1 Mon | W1 Tue | W1 Wed | W1 Thu | W1 Fri | W1 Sat | W1 Sun | W2 Mon | W2 Tue | W2 Wed | W2 Thu | W2 Fri | W2 Sat | W2 Sun |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Parent A (weekday base) | ● | ● | ● | ● | · | · | · | ● | ● | ● | ● | · | · | · |
| Parent B (extended weekend) | · | · | · | · | ● | ● | ● | · | · | · | · | ● | ● | ● |
Notice what that does: the weekday-base parent holds 4 nights of 7 and the extended-weekend parent 3, so the 60 sits on the weekday side. Move the pickup back to a Thursday and the fourth night moves with it, putting the extended-weekend parent on the 60 side instead. Both are described as 60/40, which is exactly why it pays to write the pickup day and time into the plan rather than the ratio.
When 60/40 makes more sense than 50/50
A 60/40 is often read as a 50/50 that somebody lost. Just as often it is the better fit, chosen on purpose:
- School distance. If only one home sits inside the catchment or within a short drive, concentrating the school nights there removes a daily logistics problem instead of splitting it down the middle. An equal 50/50 schedule across two long commutes is harder on the children than an unequal one that keeps mornings calm.
- Work travel and shift patterns. A parent who is away two nights most weeks cannot hold seven nights a fortnight without handing them to a babysitter. Four and three is honest about the week that actually exists. If the travel is longer than that, look at the 70/30 every-third-week pattern instead.
- The child's age. What a toddler needs from a rotation is not what a fifteen-year-old needs; short frequent contact matters more at one end, and a stable base for homework and friends at the other. Our custody schedule by age guide walks through the ranges.
- It is a step, not a ceiling. A parent who has been less hands-on can build up to substantial regular nights on a 4-3 and move to a 3-4-4-3 once the routine holds. One weeknight is the whole difference.
60/40 and child support
In a lot of places the overnight count is not a detail — it is the input. Support formulas, and sometimes which parent may claim the child on a tax return, can turn on how many nights each household has, and several jurisdictions have a threshold where the calculation changes shape. Where that threshold sits, and whether your area uses overnights at all, varies by state and by country, so there is no number worth quoting here.
Two practical consequences. First, the difference between "approximately 60/40" and a counted 209 versus 156 can matter, so put the actual pattern in the plan rather than the ratio. Second, if the schedule on paper and the schedule you live have drifted apart, the count that gets used is the one somebody can evidence. Our guide to child support under a 50/50 schedule covers how equal-time arrangements are treated and why the same questions come up one night either side of equal.
How to count your own split
Counting parenting time properly means counting overnights on a real calendar, not multiplying a weekly pattern by 52. Holidays, school breaks, a swapped weekend and a fifth weekend in a long month all move nights around, and they rarely cancel out. Run the dates through our parenting time calculator, and if you want to see how the arithmetic looks across other rotations, the custody schedule examples set them side by side.
Three rules keep the number honest: count nights rather than days so a single evening cannot be claimed twice; count the schedule as it actually happened, including the swaps; and agree the counting method with your co-parent before either of you needs it, not after.
Tracking a 60/40 schedule in SplitDay
SplitDay ships both of these as presets — a 4-3 pattern and an Extended Weekend pattern, each labelled 60/40 — so you set the pattern once, pick the day it starts, and the calendar fills itself in for every month ahead. Log exchanges as they happen and the scoreboard shows the split you are actually running, not the one written on the order. All of that is on the free plan, which is ad-supported; the free plan also exports your full custody history as a timestamped CSV you can share with a lawyer or mediator.
One parent can run the whole thing alone — the other household does not have to install anything for the calendar and the count to work. If you do want a shared calendar, one subscription runs it: the co-parent you invite views it and messages you for free, and editing needs their own plan. See what is in the app or get it for iOS or Android.
Frequently asked questions
Is 60/40 considered joint custody?
Often, but the label is set by local law rather than by the ratio. Many jurisdictions treat any arrangement where both parents have substantial overnights as joint physical custody, and a 60/40 split usually clears that bar; others reserve the term for something close to equal, or use different words entirely. What actually governs your case is the overnight count and the wording written into your order, not the shorthand. Ask a family-law professional where your case is heard which label applies.
How many overnights is 60/40?
Counted exactly against a 365-night year, 60/40 is 219 nights for one parent and 146 for the other. Counted as a repeating four-nights-and-three-nights week, it is 209 and 156 — 8 overnights against 6 in every fortnight, which is really 57/43. Both arrangements get written up as 60/40, so check which one your plan means before you rely on the number.
What is a 4-3 custody schedule?
A 4-3 schedule gives one parent the same four nights every week and the other parent the same three, on a single seven-day cycle. There is no A-week and B-week to remember and only two handoffs a week. Most families put the four-night block on the school days and give the three-night parent Friday through Sunday.
Can 60/40 become 50/50 later?
Yes, and it is a short step: on a 4-3 week the two parents are one night apart. Adding a midweek overnight for the three-night parent turns the pattern into a 3-4-4-3, where each parent alternates three- and four-night weeks and the fortnight comes out even. Running 60/40 first and stepping up once the handoffs are boring tends to stick better than starting at equal time cold. If your schedule is written into a court order, changing it is a legal step, not just a calendar edit.
Does the 60% parent get every weekend?
Usually the opposite. In the 4-3 pattern the majority parent takes the school nights, Monday through Thursday, and the 40% parent gets every Friday to Sunday — the weekend is what makes the shorter block worth having. The exception is the Thursday-to-Monday version of the extended weekend, where the long weekend itself carries four of the seven nights and puts the weekend parent on the 60 side.
