What is a Year?
The Gregorian year averages 365.25 days (31,557,600 seconds), accounting for the one leap day added every four years (with century corrections). The solar year — one orbit of the Earth around the Sun — takes about 365.2422 days, and the leap-year system keeps the calendar aligned with this astronomical period. Ages, interest rates, and long-range plans are expressed in years. The year 2000 was a leap year; 1900 was not.
What is a Hour?
The hour equals exactly 60 minutes or 3,600 seconds. It has been a core unit of timekeeping since ancient Egypt divided the day into 24 equal parts based on astronomical observation. Work schedules, travel itineraries, and TV programming are universally measured in hours. There are 8,760 hours in a common year (8,784 in a leap year).
