The 3-3-4-4 Custody Schedule: How It Works, Calendar Examples, Pros & Cons

The 3-3-4-4 custody schedule is a 50/50 arrangement built on one simple idea: each parent keeps the same weekdays every week. Parent A always has Monday to Wednesday. Parent B always has Thursday to Saturday. The two remaining "4" blocks extend each parent's time across alternating Sundays. The result is a rotation children can memorise in a day — "Mondays are Mom's, Thursdays are Dad's" — which is exactly why so many families choose it.

How Does the 3-3-4-4 Schedule Work?

The schedule runs on a two-week cycle: 3 days with Parent A, 3 days with Parent B, then 4 days with Parent A, then 4 days with Parent B. Fourteen days total, seven with each parent.

Look at the columns: Monday–Wednesday belongs to Parent A in both weeks, and Thursday–Saturday to Parent B in both weeks. Only Sunday alternates. There are just two exchanges per week — typically Thursday morning (school drop-off/pickup makes a clean, neutral exchange point) and either Sunday evening or Monday morning.

3-3-4-4 vs 2-2-3 vs 5-2-2-5: What's the Difference?

All three are 50/50 schedules on a two-week cycle, so the choice is really about trade-offs between predictability and gap length:

• 2-2-3 — shortest gaps away from each parent (never more than 3 days), but the weekdays alternate between weeks and there are 3 exchanges a week. Best for very young children.
• 3-3-4-4 — fixed weekdays, maximum 4 days apart from either parent, 2 exchanges a week. The middle path.
• 5-2-2-5 — also fixed weekdays (Mon–Tue one parent, Wed–Thu the other, alternating long weekends), but stretches to 5-day blocks. Better for older children who handle longer gaps.

If your children are settled school-age kids and you want the routine to be as boringly predictable as possible, 3-3-4-4 and 5-2-2-5 are the two finalists — and 3-3-4-4 wins where you'd rather cap the time apart at four days instead of five.

What Are the Pros of the 3-3-4-4 Schedule?

Same weekdays, every week. Activities, tutoring, training and music lessons can be booked knowing exactly which parent is on duty. Wednesday swimming is always Parent A's job. This is the schedule's killer feature and the reason schools and childminders like it too.

Never more than four days apart. Children maintain a strong relationship with both parents without the week-long gap of week-on/week-off.

Only two exchanges a week. Fewer transitions than 2-2-3, and both can be routed through school or daycare so parents in higher-conflict situations don't need to meet at all.

Both parents get weekend time. The alternating Sunday means each parent has the child for a full Friday–Sunday stretch every second week.

What Are the Cons of the 3-3-4-4 Schedule?

Weekends are split unevenly within each week. Parent B always holds Friday and Saturday nights; Parent A's weekend time comes as alternating Sundays plus their four-day block. Some parents feel this favours the Thursday–Saturday parent — if full alternating weekends matter to you, look at 5-2-2-5 or the 4-3 / 3-4-4-3 family of schedules instead.

It needs genuine 50/50 logistics. Two homes near the school, both parents able to do their weekday mornings, and workable childcare. If one parent travels for work unpredictably, fixed weekdays become a liability rather than a feature.

Midweek exchange falls on a school day. Thursday's exchange is smooth when it runs through school, but school breaks need a stated alternative exchange point in your written agreement.

What Ages Does 3-3-4-4 Suit Best?

The sweet spot is roughly ages 5 to 13. Younger children may struggle with four days away from a primary attachment figure — the 2-2-3 rotation caps that at three. Teenagers often prefer fewer moves altogether and drift toward week-on/week-off. For a full breakdown by age group, see our guide to the best custody schedules by age.

How Do You Write 3-3-4-4 Into a Parenting Agreement?

A schedule that lives in two people's memories is a schedule that gets argued about. Your written agreement should state: the named weekdays for each parent; which parent has Sunday in week one of the cycle and the date the cycle starts; exchange times and locations (with a school-holiday alternative); how holidays override the rotation; and how swaps are requested and confirmed. One evening of writing prevents years of Thursday-night texts.

Frequently Asked Questions

Is 3-3-4-4 the same as 4-4-3-3?

It's the same rotation viewed from the other parent's side, or started on a different day of the cycle. 4-4-3-3 simply begins with the four-day blocks. The weekly pattern — fixed weekdays, alternating Sunday — is identical, so pick whichever label matches your start date and don't overthink it.

Can 3-3-4-4 work with alternating full weekends?

Not in its pure form — the fixed Thursday–Saturday block means one parent always has Friday and Saturday nights. Families who want fixed weekdays and fully alternating weekends usually land on 5-2-2-5 or a 3-4-4-3 variation, which trades slightly longer blocks for a cleaner weekend rotation.

How many overnights does each parent get?

Seven nights each per fortnight — exactly 50/50. Over a full year that's roughly 182 overnights per parent, before holiday adjustments.
