7 on 7 off (Alternating Days/Nights) Shift Pattern

By Kieran - Founder

The 7 on 7 off (Alternating Days/Nights) pattern is a powerhouse schedule designed for intensive, round-the-clock operations. It offers workers the ultimate trade-off: an all-consuming work week followed by an entire week of absolute freedom.

Fact sheet

Name	7 on 7 off (Alternating Days/Nights)
Family	7 on 7 off
Applicability	24/7 continuous coverage
Employees required	4
Shift length	12 hours
Pattern length	28 days
Pattern	`DDDDDDD-------NNNNNNN-------`
Pros	26 mini-vacations (full weeks off) a year without using PTO Commute frequency cut in half (only 14 workdays every 28 days) Highly predictable long-term scheduling
Cons	Severe physical and mental fatigue by days 5, 6, and 7 The "flip" between day and night cycles is hard on the circadian rhythm Total social isolation during the intensive work week

How It Works in Practice

This pattern operates on a 28-day repeating cycle. An employee will work 7 consecutive 12-hour day shifts and then receive 7 consecutive days off. When they return to work, they switch to 7 consecutive 12-hour night shifts, followed by their final 7 days off.

To keep operations running 24/7 without a single second of downtime, a company must deploy a minimum of 4 independent crews. While two crews handle the current week's day and night shifts, the other two crews are enjoying their week off.

{{ name }} Shift Pattern Visualisation & Calculator

Our calendar tool makes it easy to create a yearly shift schedule based on the {{ name }} pattern. Simply enter your details, and the tool will quickly generate a clear and tidy rota calendar for you.

It will also calculate how many weekends you'll be working, the total hours worked, and display everything in a neat, easy-to-read rota sheet. Use this for for planning and staying organised with your shift schedule.

Hours & wage calculator

Here's a helpful calculator to work out how many hours you would work per week, month or year in the {{ name }} shift pattern.

You can also use this calculator to work out your weekly and monthly pay for {{ name }} shift schedule.

Options

Hourly rate

Results

Results recalculate automatically.

	Hours	Pay
Per week	{{ hoursPerWeek.toLocaleString() }}	${{ wagePerWeek.toLocaleString() }}
Per month	{{ hoursPerMonth.toLocaleString() }}	${{ wagePerMonth.toLocaleString() }}
Per year	{{ hoursPerYear.toLocaleString() }}	${{ wagePerYear.toLocaleString() }}

These values are based on the generated calendar above, therefore the numbers depend heavily on the start date.

Our rota software can do these calculations for you, and more.

Average weekly hours

For a {{ name }} shift pattern, the average weekly working hours is {{ hoursPerWeek.toFixed(1) }} hours.
This assumes you're working {{ hoursPerShift }}-hour shifts.

Average yearly hours

Assuming {{ hoursPerShift }}-hour shifts, your hours per year will be {{ hoursPerYear }} hours using the {{ name }} schedule.

You can use the calculator above to work out your hours for other variations of {{ name }} rota pattern.

How many weekends?

With the {{ name }} shift pattern, you will work at least one day on {{ calendar.weekends.worked }} weekends, of a total of {{ calendar.weekends.total }} weekends in the above calendar year.

So you would work {{ Math.floor(calendar.weekends.worked / calendar.weekends.total * 100) }}% of weekends with the {{ name }} pattern.

Industries

The 7 on 7 off (Alternating Days/Nights) shift pattern is commonly used in the following industries:

Healthcare (Hospitalists & Emergency Staff)
Mining & Oil Rigs
Manufacturing & Chemical Plants
Data Centers & Security

Managing the "Flip"

The most notoriously difficult part of this roster is the transition between the day shift block and the night shift block. Known as "flipping," forcing your body to invert its sleep schedule by 12 hours every fortnight requires heavy discipline, blackout curtains, and strict sleep hygiene.

If the constant flipping is deemed too hazardous or exhausting for a specific workforce, management will often pivot to a static 7 on 7 off pattern, where employees permanently belong to either a dedicated day crew or a dedicated night crew.
