A standard full-time year is 2,080 work hours — 40 hours a week times 52 weeks. The actual count varies by calendar: a year contains 260 to 262 weekdays, so at 8 hours a day the true total runs 2,080 to 2,096 hours before any vacation, holidays, or sick days come off.
How to use this calculator
- The year defaults to the current one — change it to look at any past or future year.
- Set your hours per day. Use 8 for a standard full-time schedule, 7.5 if your day runs 9 to 5 with an unpaid half-hour lunch.
- Check the days of the week you work. Monday through Friday is preselected; a four-day or weekend schedule is just a matter of toggling boxes.
- Optionally enter PTO days — vacation, paid holidays, and expected sick days combined — to subtract them from the total.
- Read the working-day and hour totals, plus the month-by-month table underneath.
Where the 2,080 figure comes from
The number you see everywhere — in salary conversions, benefits paperwork, and HR budgets — is simple arithmetic: 40 hours per week × 52 weeks = 2,080 hours. It is a convention, not a count. No calendar year contains exactly 52 weeks; a common year is 52 weeks plus one day, and a leap year is 52 weeks plus two. The 2,080 figure ignores that remainder, which is why it is so convenient: it never changes, and it makes an annual salary divide cleanly into an hourly rate. Our salary to hourly calculator uses it as the default divisor for exactly that reason.
The federal government goes one step further. For computing hourly rates of pay, the U.S. Office of Personnel Management uses a divisor of 2,087 hours, which averages the actual number of workdays over the calendar's full 28-year repeating cycle. OPM explains the derivation in its fact sheet on the 2,087-hour divisor. For private-sector back-of-envelope math, 2,080 remains the standard.
How the math works: why years vary
The calculator does not estimate — it counts. For the year you enter, it walks through every date on the calendar, checks which day of the week it falls on, and tallies the dates that match the workdays you selected. Working days × hours per day gives the annual hours, and any PTO days you entered are subtracted at the end.
That count moves around because of two things: which weekday January 1 lands on, and whether the year is a leap year. A 365-day year has 52 full weeks plus one leftover day; if that extra day is a weekday, the year has 261 weekdays, and if it falls on a weekend, 260. A 366-day leap year has two leftover days, so it can reach 262 weekdays when both extras land Monday through Friday. The full range for a Monday–Friday schedule is therefore 260 to 262 working days, or 2,080 to 2,096 hours at 8 hours a day — a swing of up to 16 hours, two full workdays, from one year to the next.
Months wobble even more. A month contains anywhere from 20 to 23 weekdays, so an 8-hour-a-day employee works between 160 and 184 hours in a given month. That spread is why hourly employees on a semi-monthly or monthly pay schedule see paycheck amounts move around even when their daily schedule never changes.
Worked example
Take a leap year that begins on a Thursday. Its two leftover days beyond 52 weeks are a Thursday and a Friday — both weekdays — so the year contains the maximum 262 weekdays. An employee working Monday through Friday, 8 hours a day, with 10 vacation days and 6 paid holidays:
- Gross working days: 262
- PTO to subtract: 10 + 6 = 16 days
- Net working days: 262 − 16 = 246 days
- Net work hours: 246 × 8 = 1,968 hours
Compare that against the 2,080 convention and the difference is 112 hours — almost three weeks of full-time work. If this employee earns a $62,400 salary, the nominal rate is $62,400 ÷ 2,080 = $30.00 per hour, but the effective rate per hour actually worked is $62,400 ÷ 1,968 ≈ $31.71. Time off you are paid for raises what each worked hour is really worth.
Annual hours by weekly schedule
At the conventional 52 weeks, annual hours scale directly with the weekly schedule:
| Hours per week | Hours per year (× 52) | Typical schedule |
|---|---|---|
| 20 | 1,040 | Half-time, 4 hours × 5 days |
| 25 | 1,300 | 5 hours × 5 days |
| 30 | 1,560 | 6 hours × 5 days, or 3 × 10-hour days |
| 35 | 1,820 | 7 hours × 5 days (9–5 with unpaid lunch) |
| 37.5 | 1,950 | 7.5 hours × 5 days |
| 40 | 2,080 | Standard full time, 8 hours × 5 days |
Full-time equivalent (FTE), in plain terms
FTE expresses a workload as a fraction of one full-time position. The formula is the employee's scheduled annual hours divided by the full-time annual hours — usually the 2,080 baseline. Someone working 20 hours a week (1,040 hours a year) is 0.5 FTE; a 30-hour-a-week employee is 0.75 FTE. The measure lets a manager say a team of three part-timers is "1.8 FTE" of staffing, and it is the unit benefits eligibility and headcount budgets are usually written in. If you are converting in the other direction — from an FTE budget to weekly hours — multiply the FTE fraction by 40, then by 52 for the annual figure. And once hours turn into pay, remember that overtime is governed by actual weekly hours, not annual averages: a 48-hour week owes overtime even in a year with plenty of slow weeks. The overtime pay calculator handles that math, and our federal overtime basics guide covers how the 40-hour threshold works.
Frequently asked questions
How many work hours are in a year?
By the standard convention, 2,080 hours (40 hours × 52 weeks). Counting the actual calendar, a Monday–Friday schedule contains 260 to 262 weekdays, so the true full-time total is 2,080 to 2,096 hours at 8 hours per day, before subtracting vacation and holidays. Enter a specific year above for the exact figure.
How many working days are in a year?
Between 260 and 262 for a five-day Monday–Friday week. The exact count depends on which weekday January 1 falls on and whether the year is a leap year. The calculator counts the real calendar for any year you enter.
How many work hours are in a month?
On average, 2,080 ÷ 12 ≈ 173.33 hours. Real months range from 20 to 23 weekdays, which is 160 to 184 hours at 8 hours per day. The monthly table above shows the actual figure for each month of the year you selected.
Why do some payroll systems use 2,087 hours instead of 2,080?
Because years do not contain exactly 52 weeks. The federal government averages the true number of workdays across the calendar's 28-year repeating cycle and arrives at 2,087 hours, the divisor OPM mandates for computing federal hourly rates. Most private employers stick with the simpler 2,080.
Does the calculator account for public holidays?
Not automatically — which holidays are paid days off varies by employer, so there is no universal list to apply. Count your employer's paid holidays together with vacation and sick days, and enter the combined number in the PTO field.
What does 1.0 FTE mean in hours?
One full-time equivalent is the full-time schedule itself — conventionally 40 hours a week, or 2,080 hours a year. Fractions scale directly: 0.5 FTE is 1,040 annual hours, 0.8 FTE is 1,664.
