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.

It was the old Roman calendar which had only 10 months in a year.
Julius Caesar introduced the Julian calendar in 46 BC. This reform created a solar calendar consisting of 365 days in a year, with an additional leap year day every four years to account for the extra quarter day. The calendar was implemented to correct the discrepancies of the previous Roman lunar calendar. The Julian calendar remained in use in various forms until the adoption of the Gregorian calendar in 1582.

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.

It doesn't seem like much, but after using the Julian calendar for 1 1/2 millennia the accumulated error totaled about 10 days.
