What is a Week?
The week is a period of exactly 7 days used across most cultures for at least 4,000 years, traditionally corresponding to the seven classical celestial bodies visible to the naked eye: the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn. Equal to 604,800 seconds or 168 hours, the week structures modern employment, religious practice, and scheduling. ISO 8601 defines Monday as the first day of the week. Fifty-two complete weeks approximate one year.
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.
