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.

No months were added. There were twelve months in the Roman calendar, just as in ours. Julius and Augustus did not add months named after themselves. The names of two of the existing months were changed to honor them.No months were added. There were twelve months in the Roman calendar, just as in ours.

Two calendars that differ from the Western Gregorian calendar are the Islamic (Hijri) calendar and the Hebrew (Jewish) calendar. The Islamic calendar is a lunar calendar consisting of 12 months, totaling about 354 days, which causes its months to shift annually with respect to the Gregorian calendar. In contrast, the Hebrew calendar is lunisolar, incorporating both lunar months and solar years, resulting in an average year length of about 354 days, with periodic leap months added to align with the solar year.
The months have never changed order, but Julius Caesar did add in two new months. He added in the months of July and August so that he and his business partner could have months named after them. This made all the months shorter.
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.
