| Split | 50/50 — 7 of every 14 nights each |
|---|---|
| Overnights in a year | 182–183 overnights per parent per year |
| Exchanges | 4 per two-week cycle (about 2 a week) |
| Longest stretch for the child | 5 nights |
The 2-2-5-5 (the same rotation started at a different point is called 5-2-2-5) is the predictable 50/50. Each parent keeps the same two weekdays every single week — one always has Monday and Tuesday, the other always has Wednesday and Thursday — and only the weekend block rotates, stretching each parent’s time into a five-night run every other week. School nights become boringly reliable, which for school-age children is the point.
The two-week pattern
| Mon | Tue | Wed | Thu | Fri | Sat | Sun | |
|---|---|---|---|---|---|---|---|
| Week 1 | A | A | B | B | A | A | A |
| Week 2 | A | A | B | B | B | B | B |
A = night at Parent A’s home B = night at Parent B’s home. The pattern then repeats.
How it works
Week 1: Parent A Monday–Tuesday, Parent B Wednesday–Thursday, then Parent A from Friday all the way through the following Tuesday — a five-night stretch. Week 2: Parent A keeps Monday–Tuesday, Parent B keeps Wednesday–Thursday, and Parent B’s five-night stretch runs from Friday through Sunday. Because the midweek anchors never move, weekly clubs, therapy appointments and parents’ work shifts can be planned around fixed days.
Advantages
- The same school nights every week — children always know whose house a Tuesday means.
- Fewer exchanges than 2-2-3: four per two-week cycle instead of six.
- Each parent gets a long weekend plus two school nights in their five-night stretch.
- Still a clean 50/50 in overnights.
Drawbacks to weigh
- A five-night stretch is too long for many toddlers and preschoolers.
- The fixed weekdays mean one parent may always get the “hard” nights (or always miss a fixed weekly activity).
- Still needs both homes reasonably close to school.
- Less flexible if a parent’s work roster changes week to week.
Who it suits
Best for school-age children, roughly ages 6 to 12, with fixed weekly routines — and for parents whose own work schedules are fixed. Families often graduate to it from a 2-2-3 when the child starts full-time school. It is a weak fit for very young children or parents on rotating shifts.
Holidays will move the real number
Everything above counts the rotation alone. Real parenting plans layer alternating holidays, school breaks and summer weeks on top — and those layers change the yearly count, sometimes by dozens of nights. The free calculator applies your actual holiday dates on a real 12-month calendar and counts the result exactly, and its compare mode shows this schedule against any other with the same holidays applied to both.

Frequently asked questions
What is the difference between 2-2-5-5 and 5-2-2-5?
Nothing but the starting point. Both describe the same 14-night cycle of 2, 2, 5 and 5 nights. 2-2-5-5 starts counting at a two-night block; 5-2-2-5 starts at a five-night block. The calendar a family lives is identical.
Is 2-2-5-5 exactly 50/50 over a year?
Effectively yes — each parent has 7 of every 14 overnights, so a real year lands at 182 and 183 overnights, with holidays moving it a few nights either way. One law-firm guide puts the cycle-only split at about 50.1/49.9 in some years; the calculator counts your actual dates.
Why do people like the fixed weekdays?
Because everything weekly — homework routines, sports practice, a parent’s late shift — happens on the same parent’s night every week. There is no “whose Wednesday is it?” question, which removes a whole category of co-parenting friction.
