There are 168 hours in a week (7 days × 24 hours). A standard full-time work week is 40 hours, and a month has between 672 and 744 hours, or about 730 hours on average. Here are all the common periods, plus what those numbers mean for planning your time and pay.
Hours in common periods
| Period | Hours |
|---|---|
| 1 day | 24 |
| 1 weekend (Saturday + Sunday) | 48 |
| 1 week | 168 |
| 2 weeks (a fortnight) | 336 |
| 28-day month (February) | 672 |
| 29-day month (February, leap year) | 696 |
| 30-day month | 720 |
| 31-day month | 744 |
| Average month | 730.5 |
| Quarter (about 91 days) | about 2,190 |
| Common year (365 days) | 8,760 |
| Leap year (366 days) | 8,784 |
Daylight saving time adds a twist: the day clocks spring forward has only 23 hours, and the day they fall back has 25. So in the US, the week containing the March change has 167 hours, and the week containing the November change has 169. See daylight saving time explained.
Working hours
| Period | Full-time (40 h/week) | Part-time (20 h/week) |
|---|---|---|
| Week | 40 | 20 |
| Two weeks | 80 | 40 |
| Month (average) | 173.3 | 86.7 |
| Year | 2,080 | 1,040 |
The 173.3 monthly figure is 2,080 ÷ 12, which is how payroll departments convert annual or hourly pay to monthly pay. The actual hours in a given month depend on its weekdays: a month with 23 working days has 184 hours, and one with 19 has 152. See working days in 2026 and 2027 for each month's count.
In the US, the federal Fair Labor Standards Act generally requires overtime pay for non-exempt employees after 40 hours in a workweek, though some states, such as California, also have daily overtime rules.
Where do your 168 hours go?
Seeing the week as a budget of 168 hours is a useful planning exercise. A typical full-time worker's week might look like this:
| Activity | Hours per week | Share |
|---|---|---|
| Sleep (8 h/night) | 56 | 33% |
| Work | 40 | 24% |
| Commuting (50 min/day) | 4 | 2% |
| Meals, chores, personal care (3 h/day) | 21 | 13% |
| Everything else | 47 | 28% |
Even with a full-time job and a full night's sleep, there are about 47 hours left each week, more than a second work week. That's the core idea behind time-management books that treat the week, not the day, as the unit to plan. For the bigger picture, the life in weeks chart shows every week of a lifetime on one page.
Quick conversions
- Hours to weeks: divide by 168. 500 hours = 2.98 weeks.
- Weekly hours to annual hours: multiply by 52. 37.5 hours a week = 1,950 hours a year.
- Hourly to weekly pay: multiply by weekly hours. $22 × 40 = $880 a week.
- Hourly to monthly pay: multiply by 173.3. $22 × 173.3 ≈ $3,813 a month.
- Hours to days: divide by 24, or see hours to days.
