The Julian Calendar is defined by its distinct structure, which consists of twelve months totaling 365 days, along with a leap year system. Each year features a standard pattern of months with varying lengths, specifically:
- January – 31 days
- February – 28 days (29 in a leap year)
- March – 31 days
- April – 30 days
- May – 31 days
- June – 30 days
- July – 31 days
- August – 31 days
- September – 30 days
- October – 31 days
- November – 30 days
- December – 31 days
In leap years, which occur every four years, an additional day is added to February, resulting in 366 days for that year. This adjustment was made to better align the calendar year with the solar year, addressing discrepancies from earlier calendar systems.
The Julian Calendar made significant contributions to timekeeping in ancient Rome. Its structure was more systematic compared to previous calendars, enhancing its practicality. The predictable 365-day cycle remains relevant today, influencing various calendar systems throughout history.
