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.
Quinquennial
A period of five years.
History/Origin
The term 'quinquennial' originates from Latin, where 'quinque' means five and 'annus' means year, and has been used since the 17th century to denote five-year intervals.
Current Use
Used primarily in planning, reporting, and events that occur every five years, such as census cycles or organizational reviews.
