For many years, up to the time of Julius Caesar the year had ten months - the remains of that
today are our last four months, which are the 9th, 10th. 11th. and 12th months, but are named in Latin September (seventh month) October (eighth month), etc. A month was added to honor Julius Caesar (July) by taking a few days from all the other months. Not to be overshadowed, August Caesar wanted the same thing (August). So it comes down to us as 12 months.

Januari and Februari
No, in the Julian calendar used in ancient Rome, a year originally consisted of 10 months. However, later two more months (January and February) were added, making the calendar year consist of 12 months.
In the Hebrew calendar, most years have twelve lunar months. Once every two or three years, a thirteenth month (the second Adar) is added in order to keep the lunar calendar in step with the solar year and its seasons.
July and August were the last two months added
Sosigenes created the calendar to follow the equinoxes. He used the Julian Calendar that was created by Julius Caesar in 46 B.C. To do this he calculated that 23 days be added after February 23rd, two months be added between the end of November and the beginning of December. Thus, adding 67 days to the "then" calendar.
