Octennial

History/Origin
The term 'octennial' has been used historically in various contexts to denote an eight-year interval, originating from Latin roots 'octo' meaning eight and 'annus' meaning year.
Current Use
Today, 'octennial' is rarely used in everyday language but may appear in academic or historical references to denote an eight-year span.
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.
