The DDNNOO schedule

In this six-day cycle, each team works two 12-hour day shifts and two 12-hour night shifts and can be covered by three teams alternating between:

Working two days, 

Working two nights, and 

Two days off. 

After one cycle ends — after six working days — the schedule starts again. 

The DDNNOO work schedule is commonly used in industries that require continuous operations and coverage, such as healthcare, manufacturing, retail, and customer service. These industries often need to ensure that they have employees available at all times to meet the demands of their customers or maintain operational efficiency. By implementing the DDNNOO schedule, they can have a rotating workforce that provides coverage for all shifts, including weekends and holidays.

Example of a 42 day DDNNOO work schedule 

D = Day shift              N = Night shift              O = Day Off

Day 1 - 42




Variations of the DDNNOO Work Schedule 

Apart from the DDNNOO work pattern, there are several other popular work schedules, including the 2-2-3 or Panama schedule, the Pitman schedule, and the Dupont schedule.

2-2-3 and Panama Work Schedule

The 2-2-3 and Panama work schedules involve 4 teams working 12 hour shifts, working in a 2-2-3 pattern.

The 2-2-3 schedule rotates between day and night shifts every 14 days, whereas a Panama schedule rotates between day and night shifts every 28 days.

Pitman Schedule

The Pitman shift schedule involves 4 teams working 12 hour shifts, working in a 2-3-2 pattern.

There are two versions of the Pitman schedule:

Version 1: Fixed Pitman schedule — the first team will always work during the day and the second team will work at night.

Version 2: Rotating Pitman schedule — teams rotate so that during one cycle one team works the day shift, and during the next cycle the same team works at night.

The DuPont Schedule

Another work pattern is the DuPont schedule, which involves a four-week cycle and consists of four stages:

Stage 1: Work four night shifts, and then take three days off.

Stage 2: Work three day shifts, have one day off, followed by three night shifts.

Stage 3: Have three days off, then work four-day shifts.

Stage 4: Have seven days off.


The DDNNOO work schedule has gained popularity as an efficient shift pattern, particularly for businesses needing round-the-clock coverage to maintain operational efficiency or meet customer needs.
