How Many Work Hours Are in a Year? The 2080 Rule Explained
The 2,080-hour work year is the backbone of every salary-to-hourly conversion in the United States. Here is exactly where it comes from, and every schedule that changes it.
A standard full-time work year is 2,080 hours: 40 hours a week times 52 weeks, or 260 workdays times 8 hours. A 37.5-hour week gives 1,950 hours, part-time schedules scale down proportionally, and paid time off means most employees actually work closer to 1,950 hours than 2,080.
The 2,080-hour rule, step by step
Start with a week: 40 hours. Multiply by the weeks in a year: 52. 40 x 52 = 2,080. That is the standard work year used by payroll systems, job postings, and salary converters across the United States. You can reach it another way: 52 weeks times 5 workdays equals 260 workdays, and 260 times 8 hours is also 2,080. Either path lands on the same number, which is why converting salary to hourly pay is a one-step division.
The rule matters because it is the convention, not because it describes anyone's real year. Employers quote it, benefits get calculated against it, and comparing any two pay structures starts by normalizing to it. But your actual hours almost certainly differ, and the differences are where the interesting money hides.
Common schedules and their yearly hours
40 hours a week: 2,080 hours. The standard. Salaried exempt roles, most hourly full-time jobs, and the basis of every salary conversion you will see quoted.
37.5 hours a week: 1,950 hours. Common in office, government, and union jobs with a 30-minute unpaid lunch. 37.5 x 52 = 1,950. On the same salary, this schedule pays a higher effective hourly rate than the 40-hour one, because the divisor is smaller.
36 hours a week: 1,872 hours. Three 12-hour shifts, the classic nursing and emergency-services pattern. 36 x 52 = 1,872.
30 hours a week: 1,560 hours. The Affordable Care Act defines full-time as 30+ hours for benefits purposes, but many employers treat 30 to 34 hours as a full part-time schedule. 30 x 52 = 1,560.
20 hours a week: 1,040 hours. The classic half-time schedule. 20 x 52 = 1,040, exactly half of 2,080, which makes part-time annualization simple: halve the full-time salary equivalent.
Work hours per month and per day
Monthly: 2,080 / 12 = 173.33 hours per month. Payroll departments use 173.33 (sometimes rounded to 173.3) to convert between hourly rates and monthly salaries. Daily: 2,080 / 260 workdays = 8 hours per day, the obvious one. These intermediate numbers are handy when a contract quotes pay per month or per day and you need to compare it against a weekly paycheck.
Paid time off changes your real number
The 2,080 figure assumes you work all 52 weeks. Almost nobody does. Two weeks of vacation (80 hours) plus, say, 6 paid holidays (48 hours) removes 128 hours, leaving 1,952 hours actually worked. Federal employees with generous leave can land near 1,900. Your salary does not change, but your effective hourly rate rises as the divisor falls: $52,000 / 1,952 = $26.64 an hour versus the quoted $25.00. When you want to match an employer's quoted rate, use 2,080. When you want the value of each hour you actually give them, use your real hours. Our salary to hourly calculator lets you set both the hours per week and the weeks per year, so you can run the conversion either way.
70 hours a week and other extreme schedules
Seventy hours a week times 52 weeks equals 3,640 hours a year, which is 1,820 hours of overtime under a 40-hour standard. At those hours, the headline salary can be deeply misleading: $70,000 / 3,640 = $19.23 an hour. This is why startup and finance salaries that look impressive often convert to ordinary hourly rates. If you are comparing offers at very different hour loads, convert each to its real hourly rate first, then compare.

Work hours in a year questions
How many hours are in a work year at 40 hours a week?
2,080 hours. That is 40 hours a week multiplied by 52 weeks a year. It is the standard figure payroll systems and salary-to-hourly conversions use.
How many work hours are in a year with a 37.5-hour week?
1,950 hours. A 37.5-hour week, common in office and public-sector jobs, times 52 weeks equals 1,950 hours per year.
How many work hours are in a month?
About 173. Divide the 2,080-hour work year by 12 months to get 173.33 hours per month for a standard 40-hour schedule.
How many hours a day is 70 hours a week?
It depends on the days: 10 hours a day across 7 days, or about 11.7 hours a day across 6 days. Over a year, 70 hours a week is 3,640 hours, with 1,820 of them overtime under a 40-hour standard.
Do holidays and vacation count as work hours?
For payroll conversion purposes, yes: the 2,080-hour standard assumes all 52 weeks. For your real effective hourly rate, no: two weeks of vacation plus holidays bring most full-time employees closer to 1,950 hours actually worked, which raises the true hourly rate.
