from the days
One year of a lunar calendar has 12 months, but it's about 11 days shorter than one year of the Gregorian calendar. A lunisolar calendar has months that are based on the cycle of the moon phases, but it also has leap years to keep the average length of a year close to the time it takes for the earth to orbit the sun. A regular year of a lunisolar calendar has 12 months, and a leap year has 13 months.
No, not our months, but there is a calendar based on lunar months.

Their counting system was based on 20, to the best of my knowledge. Also they saw the year as 360 days. This is a multiple of 20. That may explain why.

Our current calendar comes for the Julian calendar, the calendar introduced by Julius Caesar. In the 15th century pope Gregory XIII shortened the day of that calendar by about 11 minutes. Apart from that, our calendar is the same as the one introduced by Julius Caesar. Because of this, the name of our current calendar is Gregorian calendar. The Roman calendar was divided into months and the name of the months we use today are derived from the names the Romans used. For a short while at the beginning of their history, the Romans had calendar with 10 months. Soon after that, it was reformed and lengthened to 12 months. The Julian Calendar was a further reform of the Roman calendar. Two months were renamed after Julius Caesar and Augustus. This is the origin of the names of the months of July and August. The names of the other months came from the older Roman calendar.
The Chinese lunar calendar does not use months, rather divisions. The Chinese lunar calendar has 24 divisions in a year.
10 months
It was the old Roman calendar which had only 10 months in a year.
The months of the Julian calendar are the months we use today. We use the Gregorian calendar, which is a slightly modified version of the Julian calendar. The month July is named after Julius Caesar. August is named after Augustus.
No. Some countries use different calendars. So for example you have a Hebrew calendar, a Chinese calendar, an Islamic calendar, a Hindu calendar and many others. For those that use the Gregorian calendar, the months are the same around the world.
Our modern months have nothing to do with the moon's cycle, but there is a calendar based on lunar months.
The Gregorian calendar is the calendar we use today. So, yes, it does have 12 months.
