Lang calendars are a type of calendar that is used to track the lunar cycles and the solar year. They are often used in cultures that follow a lunar calendar, such as the Chinese, Japanese, and Korean cultures. Lang calendars are typically divided into 12 months, with each month being approximately 29.5 days long. They also include a number of intercalary months, which are added to the calendar in order to keep it in sync with the solar year.
Lang calendars are important because they allow people to track the changing seasons and to plan for important events, such as festivals and holidays. They are also used to determine the dates of religious ceremonies and to calculate the ages of people.
