202 1 39 day time list
2021March 9 starts from 202 1 1 8. The so-called "March 9" refers to the third "nine days" after the arrival of the winter solstice, that is, the nineteenth to the twenty-seventh day after winter. It should be noted that "the third nine days after the winter solstice" refers to "Sanjiu", that is, the day when Sanjiu intersects with Jiu Si, not Sanjiu, so Sanjiu is nine days instead of one day.
202 1 to 202 1, 1, 16, 39 days. March 9 is the lowest temperature period in the whole year. From the beginning of the winter solstice solar term, the growth rate of sunlight gradually slows down. From winter solstice to March 9, the average daily daylight time only increased by one minute. In addition, due to the slow increase of the angle between the direct angle of the sun and the ground, the daily heat budget of the ground is still in a deficit state, the northern hemisphere will continue to dissipate heat, and the ground temperature will continue to drop, resulting in a very cold climate during this period.
How to calculate the number of days on March 9?
Sanjiu refers to the coldest period of winter in the northern hemisphere, that is, the twenty-seventh cold day from winter to Sunday to everyone's day. Three or nine days is not a solar term in the traditional twenty-four solar terms, but a miscellaneous solar term. The arrival of three or nine days means that the weather has begun to enter the coldest stage. The specific calculation method is that every nine days from the winter solstice, the first nine days are called "September 19th", the last nine days are called "February 29th", and so on, and the coldest period of the year is "March 9th".
