the calendar introduced by Julius Caesar in 46 B.C. to replace the Roman calendar. In the Julian calendar a common year is defined to comprise 365 days, and every fourth year is a leap year comprising 366 days. The Julian calendar was superseded by the Gregorian calendar.
the calendar established by Julius Cesar and used as late as 1751. See calendars
A calendar in which normal years have 365 days, leap years have 366 days, and leap years are held every fourth year. Created by Sosigenes of Alexandria, but named after Gaius Julius Caesar, who hired Sosigenes for that purpose, and made it the official Roman calendar in 46 BC. Because of errors in intercalation, leap years weren't actually held every four years until 8 AD. (Of course, the terms "BC" and "AD" weren't in use in those days, and in fact weren't proposed until the 700's.)
the solar calendar introduced in Rome in 46 b.c. by Julius Caesar and slightly modified by Augustus, establishing the 12-month year of 365 days with each 4th year having 366 days and the months having 31 or 30 days except for February

n. The calendar introduced by Julius Caesar in 46 B.C. to replace the lunar calendar. The Julian calendar provided for a year of 365 days with a leap year every 4 years, or an average year length of 365.25 days. Because the solar year is slightly shorter, the Julian calendar gradually moved out of phase with the seasons and was superseded by the Gregorian calendar, introduced by Pope Gregory XIII. Compare Gregorian calendar.
The Julian calendar was introduced in 46 BC by Julius Caesar and came into force in 45 BC (709 ab urbe condita). It was chosen after consultation with the astronomer Sosigenes of Alexandria and was probably designed to approximate the tropical year, known at least since Hipparchus. It has a regular year of 365 days divided into 12 months, and a leap day is added to February every four years.
