Thirty nine days refers to the third nine days from the winter solstice, that is, the 19th-27th days after the winter solstice. The Chinese lunar calendar uses nine nineties to calculate the seasons. The winter solstice is the first day of nineteen days. Every nine days is nineteen, the first nine days are nineteen, the second nine days are twenty-nine, and so on. After ninety-one days, winter ends and spring begins. The coldest period of the year is Thirty-nine days.
