"Nine cold days" refers to the coldest days in winter. Which solar term does "Count Nine" start from?

"Count to nine" starts from the solstice in winter.

The ancients believed that the winter solstice is an important solar term for the transformation of Yin and Yang, representing the beginning of the next cycle and a day of good luck, and "counting nine" also began from then on. From the solstice in winter to nine, every nine days is a "nine". By "99", the weather turned warmer, and most parts of the country had entered spring, also known as "99 sunny day".

The date of winter solstice in Gregorian calendar every year is 65438+February 2 1-23, and 8 1 day of "99" is counted from the date of winter solstice, that is, the end of March (around the vernal equinox), "peach blossoms" and "deep spring and warm days" in Gregorian calendar. Count nine, with the emphasis on the word "number". From the winter to the Sunday of Everyone's Day, the time of each "Nine" changes every year, and it takes "counting" to find out the time period of each "Nine".

Another way is to start counting from the winter solstice, which is simpler than when the winter solstice falls on a nonzero day, because the time of each "nine" is fixed every year, and it is not necessary to find out the first nonzero day from winter to the future, so you can directly remember how many days each "nine" falls in the winter solstice.
