The 4-3 schedule gives one parent 4 days per week and the other 3 days. It provides a consistent weekly routine with the same transition days each week. It's the most common 60/40 split because it's mathematically simple — one full week, divided.
One parent (the primary) has the children Monday through Thursday every week. The other parent has them Friday through Sunday every week. Transition days are always the same: Friday after school and Monday morning. This fixed weekly pattern is the simplest non-50/50 schedule and the easiest to remember without a calendar.
Children on a 4-3 get strong school-week stability — the same parent does dropoff, helps with homework, and runs the bedtime routine every weekday. The trade-off is the 'fun parent / work parent' dynamic that can develop over time. Older kids feel this more than younger ones; younger children mostly feel the consistency. Adding a midweek dinner visit (no overnight) with the weekend parent can soften the dynamic without breaking the schedule.
A family where one parent travels for work Monday through Thursday often picks 4-3. The traveling parent gets the weekend; the home parent handles weekday school routines. The schedule works because it matches everyone's actual availability rather than fighting it.
Before locking in any custody schedule, walk through these prompts with your coparent. The schedule itself is the easy part — making it work over years requires alignment on the things below.
If you want an equal 50/50 split, switch to 2-2-3 (most frequent contact), 2-2-5-5 (fixed weekdays per parent), or alternating weeks (longest blocks). If you want a 60/40 split with weekend variety instead of every weekend going to one parent, the extended-weekend schedule rotates which weekend the primary parent keeps. If you want the secondary parent to have less time, drop to 70/30 every-weekend.
