Before Julius Caesar reformed the Roman Calendar in 46 BCE, regular years had 12 months totaling 355 days (12 lunar cycles), and leap years, or intercalary years, had 13 months totaling 377 and 378 days alternately.
Caesar changed the number of days per month as follows:
In 44 BCE, Quintilis was renamed Iulius in honor of Julius Caesar, and in 8 BCE, Sextilis was renamed Augustus in honor of Augustus Caesar.

Julian
The Gregorian Calendar is an almost identical improvement on the Julian Calendar. The names of the months and the number of days per month are the same. The only difference is that the Gregorian Calendar has three fewer leap year days out of every 400 years. The Julian Calendar averages 365.25 days per year, and the Gregorian Calendar averages 365.2425 days per year. It doesn't seem like much, but after using the Julian calendar for 1 1/2 millennia the accumulated error totaled about 10 days.
The name of Caesar's calendar was the Julian calendar. It was replaced in 1582 by the Gregorian calendar, which we used today.
The Julian Calendar was initiated by Julius Ceaser in 45B.C.
The Julian Calendar is named for Julius Caeser.
