When will the timetable start and end on March 9, 2023?

Sanjiu is a solar term, corresponding to the dog days, and it is the coldest and hottest period of the year. "March 9th" refers to the third "nine days" after the winter solstice, that is, the 19th to 27th days after the winter solstice. "The third nine days after the winter solstice" refers to "March 99", which is also the day when March 99 and April 99 intersect, not "March 99", that is, "March 99" is nine days instead of one day. People say, "it's cold for nine, and it's cold for nine in March." "March 9th" generally appears in the winter from solstice to shock.

Characteristics of three or nine days

The characteristics of winter are also very obvious. In addition to the sudden drop of climate, all crops are dormant and everything is quiet, during the winter solstice, we can also find that the direct angle between the sun and the ground becomes smaller, the time of day becomes shorter and the time of night becomes longer. The sunshine intensity per unit area of the ground is the smallest, so the ground gets the least solar heat every day, and the daily heat budget deficit of the ground has not reached the maximum. On the solstice after winter, although the day is growing day by day, the growth rate is very slow. From the winter solstice to the "March 9" period, the average daily growth is only about one minute.

Winter health

In the cold winter, we must start with keeping warm, that is to say, put on thick clothes and cover all our bodies, so as to avoid the intrusion of the cold wind and let our bodies be eroded by a murderous cold wind. In winter, we can eat some supplements properly, which can also make our bodies often have certain nutrition, which is also the best tonic time for our bodies.
