What is a Day?
The day equals exactly 86,400 seconds and corresponds to one mean solar day — one rotation of the Earth relative to the Sun. The solar day varies slightly throughout the year; the 86,400-second definition is an average. Days are the most intuitive time unit for human planning: work schedules, deadlines, and calendars are all structured around days. There are 365 days in a common year and 366 in a leap year.
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.
