What does calendar 39 mean?

March 9 in the calendar refers to the third cold day since the winter solstice, which is the coldest period of the year.

The concrete calculation method of three or nine days is based on the winter solstice, and every nine days is counted as a "nine", the first nine days are called "one nine", the last nine days are called "two nine", and so on. The coldest period in a year is "three nine, four nine days". Count to "999" 81 days, "nine peach blossoms bloom". At this time, the cold has passed and the weather is warm.

The date of the winter solstice is 65438+February 2 1~23 in the Gregorian calendar every year. From the date of the winter solstice to the eighty-first day in September, that is, the end of March (around the vernal equinox) in the Gregorian calendar, it will be the time for "peach blossoms" and "spring blossoms". Because of China's vast territory, the climate varies greatly from place to place, not all over the country. Only some areas in China correspond to the number 9 "998 1 day, 900 peach blossoms, deep in spring and warm in the day".

The weather conditions for three or nine days are as follows:
