Every Third Week Custody Schedule

The every third week schedule runs on a 3-week cycle — children spend 2 consecutive weeks with one parent, then 1 full week with the other. Best for families where distance makes frequent transitions impractical, including military families, long-distance coparents, and families separated by a multi-state move.

About this schedule

How It Works

The primary parent has the children for 14 consecutive days. Then the other parent has them for 7 consecutive days. This 21-day cycle repeats throughout the year. Transitions happen once every 1–2 weeks, which is ideal for families who live in different cities. The secondary parent gets ~122 overnights per year — much more than 80/20 alternating-weekends but still less than 50/50.

How Every Third Week Affects Children

A 14-day stretch with one parent is a real test for kids. Children 10+ usually adjust within a few cycles, especially with daily video calls during the off-week. Younger children (under 8) often experience genuine separation distress around days 8-12 of the longer block — most families using this schedule pair it with twice-daily phone or video contact and supplement with extended summer/holiday time so the year-end balance is closer to 65/35 in lived experience.

Examples in Real Families

A family where one parent moved out of state for a job opportunity often uses every-third-week. Flying the kids out monthly is expensive and exhausting; consolidating to one trip every three weeks is sustainable. School stays with the primary parent; the secondary parent's week is supplemented by daily video calls.

Pros

  • Minimal transitions — only 2 per 3-week cycle
  • Works for parents who live far apart (different cities or states)
  • Full-week blocks allow the secondary parent real quality time, not just weekend visits
  • Long stretches provide stability at each home
  • Travel costs are spread out — fewer trips per month than weekend-based schedules

Cons

  • Children go 2 full weeks without seeing one parent
  • Can be emotionally difficult for younger children
  • Travel logistics can be expensive and time-consuming
  • School enrollment typically must be with the primary parent — secondary parent provides remote/online learning support during their week
  • Difficult to coordinate weekly extracurriculars across long distance

Best For

  • Long-distance co-parenting situations (different cities or states)
  • Military families or parents who travel for work
  • Older children (10+) who can handle longer separations
  • Families using school breaks to supplement the secondary parent's time
  • Coparents where one moved post-divorce and equal parenting time isn't logistically possible

Questions to Ask Before You Commit

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.

  • Do you and your coparent live close enough to make midweek transitions practical for school, sports, and homework?
  • How will you handle holidays, school breaks, and birthdays — alternate them, split each one, or build a fixed yearly pattern?
  • What's your work schedule flexibility on school pickup, sick days, and emergencies — and how does that change month to month?
  • How will you communicate about schedule changes and shared logistics without it turning into the wrong kind of conversation?
  • What's your backup plan if the schedule stops working for either parent or the child six months in?
  • How will activities that span both households (sports, music lessons, school projects) get tracked so nothing falls through the cracks?
  • Are you both willing to use a shared calendar so neither parent has to guess what's next?

Alternatives to Every Third Week

If both parents are in the same city, every-weekend is the more common 70/30 — better for school-week consistency. If equal parenting time matters more than distance, alternating weeks (50/50) requires the same low transition frequency but assumes both parents are within commuting range. If even less time with the secondary parent is appropriate, 80/20 alternating-weekends is the next step down.
