==Julian Calendar== | |||
The Julian calendar, introduced by Julius Caesar in 45 BC, marked a major advancement in timekeeping. This solar calendar, based on the Earth's revolution around the sun, replaced the previously used Roman calendar, which was inaccurate and inconsistent. | |||
<br> | |||
Key feature of the Julian calendar include: | |||
*'''365 days:''' The Julian calendar is a solar calendar, consisting of 365 days in a common year and 366 days in a leap year. | |||
*'''12 months:''' The year is divided into 12 months, with varying lengths ranging from 28 to 31 days. | |||
**Names of the 12 months in order are: Ianuarius, Februarius, Martius, Aprilis, Maius, Iunius, Quintilis, Sextilis, September, October, November, and December. | |||
*'''Leap day:''' February gains an extra day in leap years, making it 29 days instead of 28. | |||
'''History'''<bR> | |||
Prior to the Julian calendar, the Roman calendar was based on lunar cycles and had only 355 days. This led to significant discrepancies with the solar year, resulting in seasonal misalignments and calendar adjustments being necessary every few years. Recognizing these inaccuracies, Julius Caesar, with the help of the astronomer Sosigenes of Alexandria, introduced the Julian calendar. This new system incorporated a leap year every four years, ensuring that the calendar year remained closely aligned with the solar year. The Julian calendar proved to be a major improvement, offering greater accuracy and predictability. It quickly gained widespread adoption throughout the Roman Empire and eventually much of the Western world. | |||
Despite its accuracy, the Julian calendar still had a slight discrepancy with the solar year. This discrepancy, amounting to about 11 minutes per year, accumulated over time, leading to a gradual shift in the calendar's alignment with the seasons. | |||
