How to determine the time of the onset of the 11th lunar month?

On July 11, ※, this year's three-volt curtain will officially open. Some careful members of the public found that the ambush entered last year on July 16, while the ambush entered on July 13 and July 17 in earlier years. What is the date of the fall?

According to Xiu Lipeng, a member of the Chinese Astronomical Society and an expert in astronomy popularization, the number of days for the summer solstice is not only uncertain, but it can be 30 or 40 days, and even the start date of the summer solstice varies every year.

In fact, the start date of the lunar eclipse is not based on a fixed date in the Gregorian or lunar calendar, but is calculated using the method of counting the dates of the main branches and branches. But to accurately count the dog days, it is necessary to understand the summer solstice day in the lunar calendar and the order of the stem and branch day counting method.

We know that the lunar calendar is a combination of yin and yang, and the 24 solar terms in the lunar calendar are part of the "solar calendar" - it is determined by dividing the time of the sun's movement for a year into 24 equal parts, so the time point of the solar terms is relatively fixed on the solar calendar. For example, the summer solstice is the tenth solar term among the twenty-four solar terms in the lunar calendar. In the solar calendar, the date only changes on June 20th, June 21st, and June 22nd, with the vast majority of years being June 21st.

Shortly after the summer solstice, it will be a dog day. As the saying goes, "On the third geng of the summer solstice, there will be several fu." Among them, "geng" refers to the seventh character in the heavenly stem. The meaning of this sentence is that the third Geng day after the summer solstice is the first day of the first lunar month. There is no regular pattern when this day will arrive, so we can only check the dates of the main branches on the Chinese almanac. However, what is more convenient now is that the order of dates can be easily found online.

This year's summer solstice falls on June 21st according to the Gregorian calendar. Starting from the summer solstice, the third day with the sign of Geng is the day of Geng Wu, which corresponds to the Gregorian date of July 11th. Therefore, this day has become the start date of the beginning of the summer solstice this year.

Xiu Lipeng stated that although the start date of the lunar new year is different, it all falls in mid July according to the Gregorian calendar. For the 100 years of the 21st century, it will be from July 11th to 20th. "This year is one of the earliest years of the century to enter the summer solstice."

The San Fu period can be divided into the first, middle, and last Fu periods. In terms of time, it is approximately between mid July and mid August in the Gregorian calendar, which happens to be between Xiaoshu and Liqiu. The weather is both humid and hot. In ancient Chinese poetry, various types of heat during the three seasons were depicted, such as "during the three seasons of life, there were no vehicles on the road", "the red sun filled the sky and earth, and the fire clouds formed the mountains", and "the scales of ten thousand tiles were like fire dragons, and the daily vehicles did not move. Sweat beads melted.".

Xiu Lipeng reminds the public to pay attention to heatstroke prevention and cooling during the hot and unbearable season.
