What is a 3-4-4-3 schedule?
The 3-4-4-3 schedule is a 50/50 custody pattern that rotates parents through alternating three-day and four-day blocks across a two-week cycle. Parent A has a three-day block, then Parent B has a four-day block, then Parent A has a four-day block, then Parent B has a three-day block. The cycle restarts every two weeks. Each parent always gets one three-day block and one four-day block per two-week cycle, producing exactly 50/50 time. The schedule has four exchanges per two-week cycle, half the transitions of 2-2-3 and slightly less than 5-2-2-5.
How A 3-4-4-3 Cycle Looks
Week one might look like this: Monday through Wednesday with Parent A (three days), Thursday through Sunday with Parent B (four days). Week two flips: Monday through Thursday with Parent A (four days), Friday through Sunday with Parent B (three days). The pattern then repeats. Each parent gets weekend time on alternating weeks, Parent A gets Saturday and Sunday in week one, Parent B gets them in week two. Weekdays are distributed across the two-week cycle so neither parent ends up with only school nights or only weekend leisure time.
What Ages 3-4-4-3 Works Best For
The 3-4-4-3 schedule fits children from roughly age six through fourteen. The longer blocks give school-age children enough time at each home for homework and routines to settle. The exchanges are less frequent than 2-2-3 but more frequent than alternating weeks, splitting the difference. The schedule works particularly well for families where one parent has a less predictable work schedule, the alternating block lengths can accommodate work patterns more flexibly than fixed weekday assignments. Younger children (under five) usually do better with 2-2-3. Teenagers often prefer alternating weeks.
Pros Of The 3-4-4-3 Schedule
Three benefits drive families to 3-4-4-3. First, fewer transitions, four per two-week cycle instead of the six per week in 2-2-3. Second, balanced block lengths, each parent gets both a three-day and four-day stretch, so neither feels permanently confined to short visits or long ones. Third, alternating weekends, both parents experience Saturday and Sunday with the child every two weeks, splitting the leisure time evenly. The schedule also accommodates work patterns that vary week to week, which fixed weekday schedules like 5-2-2-5 do less well.
Cons Of The 3-4-4-3 Schedule
Two trade-offs come with 3-4-4-3. First, the alternating block lengths can feel less predictable than 5-2-2-5's fixed weekday assignments, parents and children have to remember the rotation rather than relying on a constant weekly pattern. Second, the four-day blocks can stretch attention for younger children who do better with frequent contact. Most families find these trade-offs minor. The schedule's strength is its balance: fewer transitions than 2-2-3, more contact than alternating weeks, more rhythmic than 5-2-2-5.
How To Set Up A 3-4-4-3 Schedule
Setting up 3-4-4-3 starts with deciding which parent gets the first three-day block. Convention usually starts Parent A on Monday with a three-day block. The choice of starting day matters because it determines which parent gets weekends in odd-numbered weeks. Many families choose to start the rotation in a way that gives the working parent the weekend after a five-day work week, but the schedule produces the same 50/50 split regardless of starting day. Once started, the rotation is deterministic across the two-week cycle.
How 3-4-4-3 Compares To Other Schedules
Compared to 2-2-3, the 3-4-4-3 schedule has half the transitions and longer settled blocks, better for school-age children. Compared to 5-2-2-5, both have similar transition counts but 3-4-4-3 rotates weekday assignments while 5-2-2-5 fixes them. Compared to alternating weeks, 3-4-4-3 has twice the transitions and shorter blocks, more contact, less settled time. The right choice depends on whether the family values rhythmic alternation (3-4-4-3) or fixed weekday consistency (5-2-2-5). For school-age children either can work well.
How To Set Up A 3-4-4-3 Schedule In CoFam
CoFam handles 3-4-4-3 natively. Choose 3-4-4-3 in the schedule setup, pick the starting parent and starting day, and the two-week rotation populates with color-coded blocks. The overnight bridges between days show exchange timing for the four transitions per cycle. The schedule view distinguishes between week one (three-day-then-four-day) and week two (four-day-then-three-day) so the pattern is immediately legible. The time-share bar confirms the 50/50 split is holding across the two-week cycle.
