Julian Year

A Julian Year is a standard way of measuring time that equals exactly 365.25 days. This concept helps in accurately calculating long-term astronomical and calendar data. To account for the extra quarter day each year, the calendar adds a leap day every four years, making those years 366 days long. The Julian Year is useful in scientific calculations where precise, consistent measurement of years over extended periods is needed, distinguishing it from the calendar year used in everyday life. It provides a uniform framework for understanding and comparing astronomical and observational data.
