The term "月" (pronounced "yuè" in Mandarin) refers to a month in the lunar calendar. A month typically consists of 29 or 30 days, depending on the lunar cycle. In many cultures, months are used to organize time, marking the passage of days, weeks, and seasons. In the context of the Gregorian calendar, which is widely used today, there are 12 months in a year, each with a specific number of days. The concept of a month is essential for scheduling events, planning activities, and understanding seasonal changes throughout the year.
