The 3-4-4-3 Custody Schedule, Explained
How the 3-4-4-3 custody schedule works, a middle ground between 2-2-3 and week on/week off, and who it fits.
The 3-4-4-3 schedule splits time into four rolling blocks, 3 days, 4 days, 4 days, 3 days, that repeat continuously. Unlike 2-2-3, it doesn't anchor to specific weekdays; it just keeps rolling forward in the same 3-4-4-3 sequence regardless of which day it starts on.
How it works
Starting from any date:
- Days 1-3: Parent A
- Days 4-7: Parent B
- Days 8-11: Parent A
- Days 12-14: Parent B
Then the cycle repeats from day 15. Each parent gets exactly 7 out of every 14 days, an even split, distributed in blocks that never exceed 4 days.
3-4-4-3 vs. other 50/50 patterns
Three common even-split patterns differ mainly in their longest stretch:
| Pattern | Longest single stretch | Handoffs per 2 weeks |
|---|---|---|
| 2-2-3 | 3 days | 4 |
| 3-4-4-3 | 4 days | 4 |
| Week on/week off | 7 days | 2 |
3-4-4-3 keeps the same handoff frequency as 2-2-3 but stretches the blocks slightly longer, a small step toward more continuity without jumping all the way to a full week.
Who it tends to fit
- Kids who've outgrown 2-2-3's shorter blocks but aren't quite ready for a full week away from either parent
- Families whose routine doesn't map onto fixed weekdays, since 3-4-4-3 doesn't care which day of the week a block starts on
- Parents who live close enough for four exchanges every two weeks to be manageable
Where this pattern is common
No jurisdiction legally mandates a specific rotation; courts and families choose based on the child's age and what the household can sustain. Mid-length rotation patterns like 3-4-4-3 are commonly suggested in US family court self-help materials as a step between short-interval schedules and a full weekly alternation, and similar graduated approaches, starting with shorter blocks for young children and lengthening them over time, appear in shared-custody guidance across several Western European countries with high joint-physical-custody rates, including Sweden, Belgium, and the Netherlands (source).
