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.
Novennial
A novennial is a period of approximately ten years.
History/Origin
The term 'novennial' has been used historically in various contexts to denote a decade or ten-year span, though it is less common than 'decade' or 'decennial'. It originates from Latin roots 'novem' meaning nine, but in modern usage, it refers to ten years.
Current Use
Today, 'novennial' is rarely used in everyday language but may appear in scholarly or formal contexts to specify a ten-year period, especially in historical or chronological studies.
