3 on 3 off shift calendar 2026
3 on 3 off runs three 12 hour shifts, then three days off, on a 6 day cycle. Casinos, hospitals, care facilities, and continuous production lines use it when they want short blocks: nobody works more than three in a row, and no break is shorter than three days.
Because 6 does not divide into 7, the pattern walks backward through the week, one weekday per cycle. That drift keeps things fair: every crew lands near 17.3 full weekends a year, inside a tight 16 to 18 band.
3 on 3 off, days, 2026
The grid shows a crew whose cycle starts January 1, 2026; other crews run the same rotation offset by a few days. The 6 day cycle does not divide evenly into weeks, so the rotation drifts through the weekdays. Other crews get a similar year, just shifted. To line the pattern up with your real start date, use the interactive shift pattern visualizer.

Common questions
How many weekends off does 3 on 3 off give you?
17.3 on average in 2026, with crews spread only from 16 to 18. The 6 day cycle drifts through the week, so nobody is stuck with the bad weekends permanently. The January 1 crew gets 18.
How many hours a year is 3 on 3 off?
2,196 hours: 183 shifts of 12 hours, averaging 42.1 hours a week across 2026.
Does 3 on 3 off rotate through the week?
Yes, backward: each new block starts one weekday earlier than the last. After seven cycles, 42 days, it has visited every weekday and the whole thing repeats.
What does 3 on 3 off look like in practice?
Half the year off, in three day pieces. In 2026 that is 182 days off against 183 shifts, and the longest run of work is 3 shifts.
Is there a nights version of 3 on 3 off?
Plenty of sites run the same dates on nights. The calendar is unchanged, but the Friday night rule takes some weekends (a Friday night shift ends Saturday morning) and the first off day of each block becomes a recovery day. The interactive visualizer on this site can draw that variant for your exact start date.
