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.
Fortnight
A fortnight is a period of two weeks, equivalent to 14 days.
History/Origin
The term 'fortnight' originates from the Old English 'fēowertīene niht', meaning 'fourteen nights'. It has been used in English since the 16th century to denote a two-week interval.
Current Use
The term 'fortnight' is still used in British English and some other English-speaking regions to specify a two-week period, especially in scheduling and planning contexts.
