What is a hour?
An hour is 60 minutes, or 3,600 seconds, and 24 hours make one day. The hour is the standard unit for work shifts, appointments, travel times, and billing. A standard workweek is measured in hours (typically 40), and labor laws around overtime are defined in weekly hours.
Hours convert exactly to seconds, minutes, days, and weeks. Conversions to months and years use averages (30.44 days per month, 365.25 days per year) because the number of days per calendar month and year varies.

Real-world examples
A week has exactly 168 hours. A standard 40-hour workweek uses about 24% of them; adding 56 hours of sleep (8 per night) leaves roughly 72 free hours each week.
One year contains about 8,766 hours. A full-time job at 40 hours a week with two weeks of vacation is about 2,000 of those hours — less than a quarter of the year.
Freelancers and consultants bill by the hour but plan availability by the month. A month holds about 730 hours, which helps set realistic monthly targets and utilization rates.
