The relationship between the twenty-four solar terms, dog days and midsummer

The spring rain shocks the spring and the valley, and the summer is full of mountains and summer heat.

There are dewdrops in autumn, first frost in cold, light snow in winter and cold in winter.

Two festivals in a month remain the same, with a difference of one or two days at most.

The first half of the year is 62 1, and the second half is 823.

From the summer solstice, the days get longer and the nights get shorter and shorter. Summer is cloudy, and cold factors lurk in the heat, hence the name "Fu".

The dog days are divided into early, middle and late days, so they are also dog days.

The dog days are the hottest period of the year, from mid-July to mid-August in the Gregorian calendar. During this period, the days are long and the nights are short, and the sunshine is close to direct sunlight. The ground absorbs more heat and dissipates less heat every day, and gets hotter every day.

The heavenly stems and earthly branches combination formed the Jiazi Hundred Days Combination, and so on. As a result, there are sixty flowers.

The number of heavenly stems is 10, which means that there will be a Geng day every 10 day;

There are 365 days in a year (or 366 days in a leap year), which is not an integer multiple of 10. So today is Geng Day, and next year is not Geng Day. In this way, due to the uncertainty of Geng day, the date of accommodation is not the same every year.

As mentioned above, among the 24 solar terms, the minor summer heat and the major summer heat are both solar terms indicating hot summer, and the scope is only within one month.

These three days are calculated according to heavenly stems and earthly branches, not limited by months. Although there is a long coincidence time with the summer heat, they are not the same thing.

The four seasons are combined with Meng Zhongji, that is, the twelfth lunar month: Meng Chun, Midspring, Ji Chun, Xia Meng, Midsummer, Late Summer, Qiu Meng, Midautumn, Qiu Ji, Meng Dong, Midwinter and Jidong.

It is easy to sort out the relationship with the three volts and the twenty-four solar terms.

To sum up, now (16/08/0 1) is a hot summer, midsummer and the last month of summer, and my heart suddenly changes a lot. Did you get it?
