Every custody template out there assumes you work a normal week. You don't.
You know the drill: some app or lawyer-provided template hands you a schedule built around Monday-through-Friday, weekends off. Cool, except your "week off" might land on a Wednesday, and the morning that looks free on the calendar is actually the morning after a night shift that ended at 7am. If you've ever tried to force a Pitman, Dupont, or 24/48 rotation into a normal-person custody template, you already know it doesn't survive first contact.
First, work out whether your rotation drifts
This is the question that decides what kind of plan is even possible, and almost nobody asks it first. If your cycle length divides evenly by seven, your working days land on the same weekdays every cycle and you can name them in the plan. If it does not, your days off walk through the week and no fixed-weekday arrangement will hold.
| Rotation | Cycle | Days on / off | Same weekdays each cycle? |
|---|---|---|---|
| 4-on / 3-off | 7 days | 4 / 3 | Yes |
| Pitman 2-2-3 | 14 days | 7 / 7 | Yes |
| Dupont | 8 days | 4 / 4 | No |
| 5-2-5-3 | 15 days | 10 / 5 | No |
| Kelly 24/48 | 3 days | 1 / 2 | No |
If you are in the drifting group, the plan has to be expressed against the rotation — "the second day of each off-block" — and then published as three months of real dates. The rule is what the two of you agree. The dates are what the child, the school and the backup pickup actually use.
The fix isn't complicated, it's just backwards from how everyone tells you to do it. Map your actual work rotation first. Then fit custody around it — not the other way around. Sounds obvious once you say it, but almost nobody starts there, because every default template on earth starts from "the week" instead of "the shift."
The hours after a shift are not free time
Here's the thing people get wrong even after they've figured out step one: the hours right after a long shift are not free time. They're sleep debt getting paid down. If your handoff is scheduled for the second you walk in the door off a night shift, you've built a plan where you're tired, the transition is rushed, and your kid can tell something's off. Nobody planned for that to happen — it just happens by default if you don't build a recovery window in on purpose. Four to eight hours after a long or overnight shift, before any handoff, is usually enough.
Overtime is Tuesday, not an emergency
And mandatory overtime — let's be real, that's not an edge case, that's Tuesday. The plans that actually hold up have already decided, in writing, what counts as fair notice, who's the backup for pickup, and what happens to the handoff time when a 12 turns into a 16. Skip that step and every single late call becomes a fresh argument at the worst possible time to have one.
- Notice, as a number of hours. Pick one you can meet on a bad day. "As soon as I know" is not a standard anyone can be held to.
- One named backup. Agreed by both parents in advance, not assembled during the callout.
- A default for the handoff. Starts late, or moves to the next day. Choose one now.
- A cut-off. A time past which the block simply transfers, so nobody negotiates about a sleeping child at 11pm.
Look at the whole cycle, not next week
Last thing: don't just look at next week. Look at the whole rotation. A 14-day Pitman cycle can look chill in week one and then stack three handoffs against three long shifts in week two. You won't see that coming if you're only ever checking the next seven days.
Bottom line: Check whether your cycle divides by seven first — that decides whether a fixed plan is even possible. Build custody around the real rotation, protect recovery time as a written rule, settle the overtime rule before you need it, and look at the full cycle rather than next week.
