What day is the seventh day of the first month in 2023?

The seventh day of the first month in 2023 is May 9.

May 9 is the weather on May 9, that is, from winter to the 37th to 45th day in the future. The traditional 24 solar terms in China are the indispensable essence of China traditional culture.

There is a saying "Jiujiu" in the China lunar calendar, which is used to calculate the seasons. The calculation method is from the solstice of winter (counting from the solstice of winter, which means the beginning of cold), every nine days are called a nine, the first nine days are called a nine, the second nine days are called a 29, and so on until the ninth nine days, when the number reaches 998 1 day. At this time, winter has passed and spring has arrived.

In ancient times, the number nine paid attention to counting from a single day, that is, the winter solstice coincided with the single day of the lunar calendar, so this day was the first day of the ninth lunar month and was called "Li Andong Nine". If it falls on a double day, it will be postponed for one day, and it will be called "Wearing Winter Nine" from the next day. In the future, people seem to agree that after the 998 1 day, the winter solstice will count to nine. The cold disappears completely and the sun shines high, so it is called "99 sunny day".
