How to calculate work hours in a year
Annual work hours start with a schedule: hours per workday, workdays per week, and working weeks per year. The calculator also supports a weekly-hours mode when you already know your weekly total.
How many work hours are in a year at 40 hours per week?
A 40-hour week across 52 working weeks is 2,080 scheduled work hours per year. Actual worked hours can be lower after PTO, holidays, and other non-working days.
Work hours per month
Average monthly work hours are annual work hours divided by 12. For 2,080 annual work hours, the average is about 173.33 hours per month. Actual calendar months can have different numbers of working days.
Workdays in a year
Workdays per year are calculated as workdays per week times working weeks per year. A 5-day week across 52 weeks is 260 scheduled workdays before subtracting holidays, PTO, or other time away.
Adjusting annual work hours for PTO and holidays
Scheduled annual work hours and actual estimated annual work hours are different. Time off is only subtracted in schedule mode, where hours per workday is known.
Annual work hours examples
A four-day schedule can still equal 2,080 annual hours when it uses 10-hour days: 10 x 4 x 52 = 2,080. Days per week alone does not determine annual hours.
How many total hours are in a year?
A normal 365-day calendar year contains 365 x 24 = 8,760 total hours. A 366-day leap year contains 366 x 24 = 8,784 total hours.
Calendar hours are not the same as working hours. A 40-hour workweek across 52 weeks is 2,080 work hours per year, far less than the total hours in the calendar year.
