What is a 9/80 work schedule?
A 9/80 schedule compresses 80 hours of work into nine days over a two-week period. In the first week you work five days — four 9-hour days plus one 8-hour day. In the second week you work four 9-hour days and get the fifth day off. Your total is still 80 hours, but you gain one extra full day off every other week. Many offices, government agencies, factories and hospitals use 9/80 because it adds rest days without cutting pay.
How to use this calculator

Quick facts about 9/80 schedules
- Two-week total: 80 hours — the same as a standard 5×8 schedule.
- Long week: 4 days × 9 h + 1 day × 8 h = 44 hours.
- Short week: 4 days × 9 h = 36 hours, with the flex day off.
- You gain 26 extra days off a year compared with a standard 5×8 week.
- Overtime rules vary. Under a 9/80 agreement, OT usually starts after 80 hours in two weeks, not after 40 hours in one week.

Why the 9/80 schedule matters
- It gives you a full weekday off every other week for appointments, family or rest.
- It saves one full commute every two weeks, which means less fuel and less traffic stress.
- It keeps your total hours the same as a normal schedule, so your pay does not change.
- Longer days need better planning: meals, rest and focus matter more across nine hours.
- Knowing your exact hours helps you check your payslip and understand overtime rules.
Conclusion
A 9/80 schedule gives you one extra day off every two weeks while keeping your total hours the same as a standard week. Use this calculator to check your long and short shift end times, your bi-weekly hours and your estimated pay before you accept an offer or plan your month.
Frequently asked questions
What is a 9/80 work schedule?
A 9/80 schedule compresses 80 hours of work into nine days over a two-week period. You typically work four 9-hour days plus one 8-hour day in the first week, then four 9-hour days with the fifth day off in the second week.
How many hours do you work in a 9/80 schedule?
80 hours over nine days in a two-week cycle. That is 44 hours in the five-day week and 36 hours in the four-day week, averaging 40 hours per week.
Is 9/80 considered full time?
Yes. Because the two-week total is 80 hours (40 per week on average), most employers treat it as full-time work.
Do you get overtime on a 9/80 schedule?
Usually not if your employer uses a 9/80 agreement, which averages hours over two weeks so overtime starts after 80 hours instead of 40. Without such an agreement, the 44-hour week may include 4 hours of overtime depending on local law.
How many extra days off do you get with 9/80?
One extra day every two weeks, which works out to 26 extra days off a year compared with a standard 5×8 schedule.
How long is a 9-hour shift with a break?
With a 30-minute unpaid break, you are at work 9.5 hours and paid for 9. Add your commute and it becomes a long day, so plan meals and rest.
Is 9/80 better than 5/8?
It depends on you. A 9/80 schedule gives you 26 extra days off a year but longer working days. A 5/8 schedule has shorter days and more daily flexibility.
