The original Roman calendar, traditionally attributed to Romulus, had ten months, beginning in March and ending in December. These months were followed by a winter period that was not assigned to any month. Later, around 713 BCE, King Numa Pompilius added January and February, making a total of twelve months in the calendar.

The Aztec calendar was composed of 18 months. The calendar consisted of a 365-day calendar cycle called xiuhpohualli (year count) and a 260-day ritual cycle called tonalpohualli (day count). It is an agricultural calendar, based on the sun.
The ancient Egyptian calendar consists of 12 months, each with 30 days, totaling 360 days. Additionally, there are five extra days added at the end of the year, known as the "epagomenal days," bringing the total to 365 days in a year. This calendar was primarily used for agricultural and religious purposes in ancient Egypt.
The original Roman year had 304 days, because the months of January and February were not taken into account.
In 46 B.C., Julius Caesar reformed the Roman calendar, transitioning from the lunar-based calendar to the Julian calendar. To realign the calendar with the solar year, 90 extra days were added that year, resulting in a total of 445 days for that year, which is often referred to as the "year of confusion." This significant adjustment helped establish a more accurate calendar system that later influenced the Gregorian calendar we use today.
The Roman Calendar has 10 months in its system. Among these ten months, there were 304 days. This has been expanded on to 12 months and 365 days, which is still used today.
In the past the zodiac was a calendar for many cultures. The signs represented different parts of the year. When the Roman calendar was finally introduced, this was taken into account.

The Romans had three calendars over the 1,200 years of their history. Only the first one, the Romulean calendar created by Romulus, Rome's first king, had 10 months and this lasted only for about 40 years. The second king of Rome, Numa Pompilius, reformed the calendar and created one with 12 months (the calendar of Numa). The Julian calendar, created by Julius Caesar, also had 12 months. Caesar also switched from a lunar to a solar calendar.
The Chinese lunar calendar does not use months, rather divisions. The Chinese lunar calendar has 24 divisions in a year.

The months of the year originated from the Roman calendar, which was initially a lunar calendar consisting of ten months, starting with March. Later, around 713 BCE, January and February were added, creating a twelve-month system. The names of the months were derived from Latin, with many reflecting numbers (like September for the seventh month) or honoring Roman gods and leaders. The modern Gregorian calendar, adopted in 1582, further refined this system but retained the original month names.
