Year (Julian)
A year (Julian) is the period of time approximately 365.25 days, based on the Julian calendar, used to measure the length of a complete cycle of seasons and calendar years.
History/Origin
The Julian year was introduced by Julius Caesar in 45 BC as part of the Julian calendar reform, replacing the Roman calendar. It standardized the year length to 365 days with a leap year every four years to account for the extra quarter day.
Current Use
The Julian year is primarily used in astronomical calculations and historical contexts. It is also the basis for the Julian date system used in astronomy and other sciences to record continuous days.
Quindecennial
A quindecennial is a period of fifteen years.
History/Origin
The term originates from Latin, where 'quindecim' means fifteen, and has been used historically to denote a fifteen-year interval, often in contexts like anniversaries or historical cycles.
Current Use
The term 'quindecennial' is rarely used in modern times; more common references to fifteen-year periods are made using 'quindecennial' mainly in historical or formal contexts, such as quinquennial (five-year) or sesquicentennial (150 years).
