How to calculate the date of the Millennium

[Y*D+C]-L

Interpretation of the formula: Y= 2 digits after years, D=0.2422, C= leap year, 2 1 century C=7.646, 20th century C=8.44, and L= 2 digits after years divided by 4.

For example, the Millennium date of 20 13 = [13× 0.2422+7.646]-[13/4] =10.7946-3.25 = 7.5446, and September 7th is the Millennium.

Exception: 1927 plus 1 day.

The meaning of Millennium solar terms

The Millennium is one of the twenty-four solar terms in the lunar calendar, and it is called the Millennium solar term when the sun reaches 165 degrees. Millennium is the third solar term in autumn, indicating the end of Qiu Meng and the beginning of Mid-Autumn Festival. Dew is water droplets formed by condensation of water vapor on the ground or near-earth objects due to temperature drop. So the Millennium actually indicates that the weather is getting cold. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. The temperature difference between day and night can reach more than ten degrees. Yang Qi reached its peak in the summer solstice, and these two extremes must be reversed, and Yin Qi also rose at this time. When it comes to the White Dew, the yin gradually increases, and the morning dew gradually thickens and condenses into a layer of white water drops, so it is called the White Dew.

"White Dew" is a festival that reflects the temperature changes in nature. Dew is a unique natural phenomenon after the solar term of "White Dew". The weather at this time, as the Book of Rites said: "The cool wind comes, the dew falls, and cicadas sing." According to the explanation of "white dew" in the twenty-four solar terms-"water and soil condense dew, autumn belongs to gold, golden white and white dew, and qi begins to be cold". The ancients also said in Xiao Weijing: "The fifteenth day after the summer heat is white dew", and the yin is getting heavier and heavier, and the dew condenses into white. In fact, meteorology shows that at this time of the solar term, the weather becomes cool and the sun is still very hot during the day. But as soon as the sun returns to the mountains, the temperature will drop rapidly. At night, the water vapor in the air will condense and form tiny water droplets, which are very densely attached to the green stems, leaves or petals of flowers and trees and are white. Especially after the morning sun exposure, it looks more crystal-clear and attractive, thus obtaining the beauty of "White Dew".

1, Lai Hongyan

The swan goose is very small. It comes from the north to the south. It's not called Nanxiang, but its ears. For details, please refer to the rain festival (three rains: "First-class Rex sacrifices fish; Second, wait for Hongyan to come; Third-class grass sprouts ").

The mysterious bird is back.

"Twenty-four solar terms": "The mysterious bird sees the vernal equinox (at the beginning of the vernal equinox, the mysterious bird arrives; At this time, Yan came from the north and moved to the south. Yan is a bird in the south, so he came back.

3. Birds bring shame

More than three animals are groups, and there are many groups. The Book of Rites records: "Those who are ashamed will eat soup." Those who mention shame hide it and wait for the winter moon. Shame is the original word of shame. In ancient times, "shame" and "shame" were universal. Raising shame is a Chinese word, and the pinyin y m ngxi \u refers to the stored food "Yi Zhou Shu Shi Xun": "On the day of the white dew, the geese come, on the fifth day, the mysterious birds return, and on the fifth day, the birds raise shame. You Zhu once explained: "Those who are honest and ashamed hoard winter food, as if they are hiding precious shame. "
