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.
Millennium
A millennium is a period of 1,000 years.
History/Origin
The term 'millennium' originates from the Latin 'millennium', meaning 'a thousand years'. It has been used historically to mark significant 1,000-year periods, often in religious or historical contexts.
Current Use
Today, 'millennium' is commonly used to refer to the 1,000-year period from the year 2000 to 3000 or to describe a span of a thousand years in various contexts such as history, planning, and cultural references.
