A twelve month lunar calendar is based on the cycles of the moon, with each month following a complete lunar cycle of approximately 29.5 days. This type of calendar typically has around 354-355 days in a year. In contrast, a twelve month solar calendar, like the Gregorian calendar, is based on the Earth's orbit around the sun, with each month roughly following the natural seasons. This calendar has 365 days in a common year and 366 days in a leap year.
A 12-month calendar was developed during the Shang Dynasty.
