Year
A year is the period of time it takes for the Earth to complete one orbit around the Sun, approximately 365.25 days.
History/Origin
The concept of a year has been used since ancient times, with various civilizations developing calendars based on lunar and solar cycles. The Gregorian calendar, introduced in 1582, standardized the length of the year as 365 days with a leap year every four years to account for the extra quarter day.
Current Use
The year is widely used as a basic unit of time measurement for calendars, planning, and record-keeping worldwide, with the Gregorian calendar being the most common system in use today.
Year (Leap)
A leap year is a year that has 366 days, including an extra day (February 29) added to keep the calendar year synchronized with the astronomical year.
History/Origin
The concept of adding an extra day to the calendar was introduced by the Julian calendar in 45 BC and refined by the Gregorian calendar in 1582 to correct inaccuracies in the Julian system, establishing the current rules for leap years.
Current Use
Leap years are used in the Gregorian calendar to maintain alignment with Earth's orbit around the Sun, occurring every four years with exceptions for century years not divisible by 400, ensuring calendar accuracy over long periods.
