Types of Custody Schedules: 50/50, 60/40, 70/30, and 80/20
The major custody-schedule families are equal-time rotations such as alternating weeks, 2-2-3, 3-4-4-3, and 2-2-5-5; approximately 60/40 schedules such as a repeating 4-3 week; 70/30 schedules such as every weekend or alternating weekends plus a weekly overnight; and primary-residence schedules such as alternating extended weekends. The percentages are shorthand, not exact definitions. Count actual overnights, exchanges, and longest separations, then choose the pattern that fits the child's age, school, distance between homes, safety, and each parent's real availability.
A custody schedule is much easier to evaluate when you can see the rotation instead of decoding a string of numbers.
This guide maps the most common parenting-time schedules onto real calendars. It shows who has each overnight, how frequently children change homes, how long they may go without seeing either parent, and what each arrangement asks of the family.
The examples use Parent A and Parent B rather than assigning a schedule by gender. They are illustrations, not prescriptions. Exchange times, holidays, school breaks, travel, safety provisions, and local court requirements can all change how a schedule operates.

How to Read the Calendar Examples
Each colored cell represents the parent responsible for that overnight. An exchange may happen after school, at daycare, or at another agreed time before that overnight begins.
The percentages are shorthand. A fourteen-night cycle cannot produce an exact 60/40 split because 60% of fourteen is 8.4 nights. That is why an 8/6 schedule is usually described as approximately 60/40, even though it is mathematically 57/43. Count the complete repeating cycle—and the annual holiday schedule—when the exact percentage matters.
Custody Schedules at a Glance
| Schedule | Typical split | Longest block | Exchange pattern | Defining tradeoff |
|---|---|---|---|---|
| Alternating weeks | 7/7 · 50/50 | 7 nights | Once each week | Few exchanges; longer separation |
| 2-2-3 | 7/7 · 50/50 | 3 nights | Three times most weeks | Frequent contact; frequent handoffs |
| 3-4-4-3 | 7/7 · 50/50 | 4 nights | About twice each week | Medium blocks; weekend structure needs attention |
| 2-2-5-5 | 7/7 · 50/50 | 5 nights | About twice each week | Fixed weekdays; longer five-day stretches |
| Two weeks each | 14/14 · 50/50 | 14 nights | Every two weeks | Very few exchanges; very long separation |
| Repeating 4-3 | 8/6 · 57/43 | 4 nights | Twice each week | Simple weekly pattern; weekends stay fixed |
| Every weekend | 10/4 · 71/29 | 5 nights | Twice each week | Stable school week; uneven weekday/weekend labor |
| Alternating weekend + midweek | 10/4 · 71/29 | 6 nights | About three times each week | Regular contact; more transitions |
| Alternating extended weekend | 11/3 · 79/21 | 11 nights | Twice every two weeks | One primary home; long gap between visits |
50/50 Custody Schedules
Equal-time schedules give each parent seven of fourteen overnights. They can look very different in practice: one schedule may involve a handoff every two or three days, while another may keep the child in one home for a full week or two.
Alternating Weeks: The 7-7 Schedule
The child spends one full week with Parent A and the next with Parent B. The exchange often happens after school on Friday or Monday so the school day becomes the transition point.
Best known for fewer exchanges and long, uninterrupted parenting blocks.
This arrangement is easy to remember and gives both homes a complete mix of school nights and weekends. The central question is whether seven nights away from either parent fits the child’s age, temperament, and existing relationships. See the full week-on/week-off custody guide for variations, transition planning, and parenting-plan details.
The 2-2-3 Schedule
Parent A has two nights, Parent B has two nights, and Parent A has the three-night weekend. The next week flips, giving Parent B the three-night weekend.
Short separations can help some younger children, but three weekly exchanges demand close homes and reliable logistics.
Because the weekday pattern flips, adults must look at the actual calendar rather than assume that Tuesday always belongs to one household. Our complete 2-2-3 custody schedule guide covers school, activities, belongings, and neutral schedule-change language.
The 3-4-4-3 Schedule
This rotation creates consecutive blocks of three, four, four, and three nights. In the example below, Parent B receives both weekends. A family that wants alternating full weekends should select a different anchor or write a separate weekend rule.
A middle ground between rapid 2-2-3 transitions and a full seven-night separation.
Read the 3-4-4-3 custody schedule guide for alternative start days and a direct comparison with 2-2-3 and 2-2-5-5.
The 2-2-5-5 Schedule
Parent A always has Monday and Tuesday. Parent B always has Wednesday and Thursday. The Friday-through-Sunday weekend alternates, creating a five-night block when a parent’s weekend connects to their fixed weekdays.
Children know which home owns each school night, while both parents receive alternating full weekends.
The predictability can simplify school, childcare, and activities. The five-night stretch is the main tradeoff. See the 2-2-5-5 custody schedule guide for a deeper comparison and parenting-plan checklist.
Two Weeks Each: The 14-14 Schedule
Each parent receives fourteen consecutive nights. This is still 50/50 over four weeks, but it has half as many exchanges as alternating weeks and twice the separation.
Usually considered for older children, long-distance logistics, or families whose work makes weekly exchanges impractical.
The logistical simplicity is real, but fourteen nights is a long absence. The plan also needs a reliable method for sharing school, medical, and activity information across the entire block.
60/40 Custody Schedules
“60/40” usually means one parent has slightly more overnights, not necessarily an exact sixty percent. Over fourteen nights, the closest simple split is 8/6, or approximately 57/43. A 9/5 cycle is approximately 64/36.
The Repeating 4-3 Schedule
Parent A has four fixed nights and Parent B has three fixed nights every week. The example keeps the school week with Parent A and every Friday-through-Sunday overnight with Parent B.
Simple and predictable, but one parent receives nearly all school nights while the other receives every weekend.
Families can rotate weekends or move the four-night block to reduce the “responsibility parent versus fun parent” divide. Those changes also make the rotation more complex, so write the full cycle rather than relying on the phrase “60/40.”
70/30 Custody Schedules
A 10/4 split over fourteen nights is approximately 71/29. Two common ways to reach it are every weekend or alternating weekends combined with a weekly midweek overnight.
Every Weekend
Parent A has Monday through Friday overnights and Parent B has Saturday and Sunday overnights in this example. If the exchange happens Friday evening, Parent B may instead receive Friday and Saturday overnights before the child returns Sunday.
The school routine is highly consistent, but neither parent experiences the full range of ordinary weekdays and open weekends.
This arrangement can fit work or distance constraints, but the distribution of labor deserves explicit attention. The weekday parent may carry homework, appointments, and early mornings; the weekend parent may lose nearly all unstructured weekends. Our 70/30 custody schedule guide covers several ways to rebalance those responsibilities.
Alternating Weekends Plus a Weekly Overnight
Parent B receives one midweek overnight every week plus two overnights on alternating weekends. The regular midweek contact shortens the gap without transferring every weekend.
More frequent contact than alternating weekends alone, with more packing, transportation, and school-night coordination.
The parenting plan should specify whether the midweek time is an overnight, dinner visit, school pickup, or another arrangement. Those choices affect both the child’s routine and the actual overnight percentage.
80/20 Custody Schedules
An 11/3 split over fourteen nights is approximately 79/21. That can be created with one three-night extended weekend every other week. A two-night alternating weekend produces 12/2, or approximately 86/14, even though it is sometimes casually called “80/20.”
Alternating Extended Weekends
Parent B has Friday, Saturday, and Sunday overnights every other week, often picking up after school Friday and returning the child to school Monday morning.
Very few exchanges and one clear primary home, but an eleven-night separation between Parent B's blocks.
A midweek dinner or call can create contact without changing the overnight count. If the goal is to increase parenting time, the order or agreement should say whether that contact is an overnight and who handles transportation.
Alternating Two-Night Weekends
If Parent B receives only Friday and Saturday overnights every other week, the split is 12/2—approximately 86/14 rather than 80/20.
The label matters less than the written dates: specify the actual pickup, return, and overnight sequence.
This is why a parenting plan should not rely on percentages alone. “Every other weekend from Friday at 5:00 p.m. until Sunday at 5:00 p.m.” is far clearer than “approximately 80/20.”
Other Parenting Schedule Arrangements
Not every parenting arrangement is best understood as a two-week percentage. Some families organize the home, school year, or work roster first and allocate parenting responsibility around it.
Bird’s-Nest Custody
The children remain in one family home while the parents rotate in and out. The example uses alternating weeks for the on-duty parent, but bird’s-nest custody can use almost any underlying rotation.
The children's physical transition disappears, but the parents must manage housing costs, shared-space rules, privacy, maintenance, and new relationships.
Bird’s-nest custody can reduce disruption for children during a transition. It also demands unusually clear agreements about money, cleaning, food, belongings, guests, and the duration of the arrangement.
Long-Distance: School Year and Summer
When the homes are too far apart for ordinary weekly exchanges, one parent may have most of the school year while the other receives larger summer and school-break blocks. The illustration is only one example; holidays and travel days must be written separately.
Travel responsibility, airfare, missed connections, virtual contact, holidays, and the exact start and end of summer all need explicit rules.
For the practical details, see our guides to coparenting after a move, relocation and custody planning, and summer custody schedules.
Custom and Irregular Schedules
Shift work, military duties, airline schedules, emergency-response work, trucking, and rotating rosters may not fit a named two-week pattern. A custom schedule should still have a repeatable decision process:
- Mark each parent’s known work and sleep requirements.
- Protect the child’s school, childcare, medical, and activity commitments.
- Identify the parent responsible for every overnight and exchange.
- Set a deadline for publishing the next schedule period.
- Define what happens when a roster changes after that deadline.
- Keep the agreed schedule and every later change in one shared record.
Our specialized guides cover shift-work custody schedules, rotational work, first responders, airline crews, and truck drivers.
How to Choose a Custody Schedule
Do not start with the percentage. Start with the child’s life and test each candidate schedule against the same questions.
1. How Long Can the Child Comfortably Be Away From Either Parent?
Age matters, but it is not the only factor. Consider the child’s temperament, established attachments, previous care patterns, developmental needs, and response to transitions. Our custody schedules by age guide walks through these considerations from infancy through the teenage years.
2. How Many Exchanges Can the Family Reliably Manage?
A 2-2-3 schedule creates frequent contact and frequent handoffs. Alternating weeks create fewer handoffs and longer separations. Count driving time, school bags, medication, sports equipment, homework, and the emotional effect of each transition—not just the overnights.
3. Do the Homes Support the Same School and Activities?
Equal-time rotations are easier when both homes can reliably reach school, childcare, healthcare, friends, and activities. Distance can turn an elegant calendar into exhausting daily travel.
4. Does the Pattern Divide Ordinary Parenting Fairly?
Look beyond the number of nights. Who gets homework, early mornings, appointments, sick days, and transportation? Who gets unstructured weekends and holidays? A mathematically balanced schedule can still distribute the work and the relationship very unevenly.
5. Are Communication and Safety Conditions Compatible With the Schedule?
Schedules with frequent exchanges require more coordination. When direct contact is unsafe, highly conflictual, or routinely destabilized, fewer exchanges, school-based handoffs, parallel-parenting boundaries, supervised exchanges, or other protections may be necessary. Safety takes priority over symmetry.
6. Is the Schedule Written Precisely Enough to Follow?
A complete parenting schedule should identify:
- The first date of the repeating cycle
- The parent responsible for each overnight
- Exchange days, exact times, locations, and transportation
- School-day and non-school-day handoffs
- Holidays, birthdays, vacations, and school breaks
- Notice and approval rules for temporary changes
- Sick days, closures, travel delays, and missed exchanges
- Phone or video contact during longer separations
- A review date as the child’s needs change
The parenting plan guide and parenting-plan checklist can help turn the chosen rotation into complete operating rules.

Frequently asked questions
What are the most common 50/50 custody schedules?
Alternating weeks, 2-2-3, 3-4-4-3, and 2-2-5-5 are common equal-time patterns. Alternating weeks minimizes exchanges, 2-2-3 keeps separations short, and 2-2-5-5 gives each parent consistent weekdays with alternating weekends.
What does an 80/20 custody schedule look like?
A close two-week example is 11 overnights with Parent A and 3 with Parent B, often created by an alternating extended weekend from Friday after school through Monday morning. A two-night alternating weekend is 12/2, or about 86/14, even though people sometimes loosely call it 80/20.
How do you calculate a custody percentage?
Count each parent's overnights during the full repeating cycle, divide by the total overnights, and multiply by 100. A 10/4 split over fourteen nights is approximately 71/29; an 11/3 split is approximately 79/21. Holidays and vacations can change the annual result.
Which custody schedule is best for a young child?
There is no universal best schedule. Younger children often benefit from predictable routines and shorter separations, while older children may tolerate longer blocks with fewer exchanges. Consider the child's temperament, attachments, school, travel time, established care, and safety.
How can BestInterest help manage a custody schedule?
BestInterest's Shared Calendar displays the custody rotation, exchanges, appointments, activities, tasks, and approved changes in one place. Formal schedule-change requests and approvals are available on Connect and higher, while Solo Mode lets one parent maintain the complete schedule even if the other parent never joins.
