Why is May a midnight battle?

May is a midnight oil, mainly because the solar term in May is long summer, and the first night after long summer is a midnight oil.

The trunk calendar is a traditional method of timing in China, which consists of heavenly stems and earthly branches. The trunk and branch in the trunk and branch calendar are combined in turn by ten-day trunk and twelve-day branch. Night Fight refers to the Big Dipper, which is now known as the "North Star". Its position in the sky is relatively fixed. According to the characteristics of the dry calendar, the dry branches of each month are fixed, while the night battle depends on the change of solar terms. So in May, because it is the first night after the long summer solar terms, the corresponding night battle is dry night battle.

The practical solution is to understand why May is a midnight oil by studying the traditional culture and branches of China. If you want to know more about Ganzhi Calendar and China traditional culture, you can learn by reading related books or participating in cultural activities.
