In China's lunar calendar, months are divided into large and small months. A large month refers to a month with 30 days, and a small month refers to a month with 29 days. However, the size of the lunar months is not fixed. Any month that falls as a large month will have 30 days, and any month that falls as a small month will have 29 days. Regardless of the year, the lunar second month will never have only 28 days.

The second month is commonly known as: Xingyue (Apricot Month), Zhongchun (Mid-Spring), Zhongyang (Mid-Sun), Ruyue (Like Month), Liyue (Beautiful Month), Huayue (Flower Month), Zhongyue (Mid Month), Han Yue (Drunk Month).
