60/40 Custody: The 4-3 Schedule
A 60/40 schedule gives one parent a modest majority of time while keeping the other deeply involved every single week. The classic version is the 4-3: four days with one parent, three with the other, identical every week.
How the 4-3 rotation works
Each week the children spend the same four days (for example Sunday–Wednesday) with Parent 1 and the same three days (Thursday–Saturday) with Parent 2. Over a 28-night cycle that's 16 and 12 overnights — 57.1% / 42.9%, the split families and courts commonly refer to as "60/40."
Because the pattern never changes, routines are simple: same school days, same weekend block, about two exchanges per week.
Other ways to get to 60/40
- Every weekend Friday–Sunday (three overnights weekly) — about 57/43, and it gives the weekday parent every school night. Choose Every Weekend in the dropdown to preview it.
- Extended alternating weekends plus a weekly overnight — lands close to 60/40 with fewer exchanges.

Common Questions
Is 60/40 actually 60/40?
The common 4-3 version computes to 57.1/42.9 by overnights — close enough that everyone calls it 60/40. If a precise number matters for your case, model your exact calendar in the tool.
When do courts consider a 60/40 schedule?
It often fits when both parents are actively involved but a perfect 50/50 isn't practical — for example one parent's work schedule can't cover certain school nights. The controlling standard in California is always the child's best interests.
Does 60/40 vs 50/50 change child support?
Timeshare percentage is a factor in California's guideline formula, so the difference can matter. The exact effect depends on incomes and other factors — get guideline numbers from the court's calculator or an attorney.
