Why is the fifth day of May unlucky?

Because the fifth day of May is the last day of poisonous gas.

In ancient times, the fifth day of May was the most poisonous day every year, so it was called evil month and evil day. I think that children born on this day will be rude to their parents, so I either abandon them or change my birthday.

The environmental conditions in May are harsh. This month includes the awn species and the summer solstice in the 24 solar terms. This month, the climate will become more severe, and the overall temperature will rise and become hot. At the same time, there will be a rainy season before and after the awn seeds, and the humidity is very high. In a word, this month is very suitable for the reproduction and growth of viruses and bacteria, and many floods are called bad months.

In fact, the date itself is not good or bad, and many traditions and sayings have been handed down from ancient times. People in ancient times believed in ghosts and gods. With the development of the times and the improvement of people's medical level and living conditions, people are no longer greatly influenced by the environment. May is poisonous, May is evil, and the fifth day of May is unlucky.
