Who can tell me some little knowledge?

"The solar calendar follows the sun and the lunar calendar follows the moon" is not accurate. No matter what kind of calendar, it is inseparable from the sun. The solar calendar comes from the movement law of the intersection angle between the sun and the earth, and the earth changes with the change of the intersection angle. Lunar calendar is a traditional calendar in China, also called lunar calendar, which is closely related to traditional agricultural society. In ancient times, the calendar was accurately calculated by the maximum direct angle of the sun and the phase of the moon, both of which were related to the sun, but the error of the lunar calendar was slightly greater than that of the solar calendar, such as the arrival of the twenty-four solar terms. The biggest feature of the lunar calendar is that the tides are closely related to the gravity of the moon (related to the change of solar terms), and the fifteenth moon will be round. ...

"The sun is dizzy in the middle of the night, it rains again, and the moon is dizzy at noon."

"Sunshine and Rain on the Third Night" The sun is extremely hot during the day, but it still produces a halo, indicating that the water vapor is quite humid and rain is bound to be produced at night (the temperature is the lowest on the third night);

"Moon halo and afternoon wind" is the opposite of solar halo. The temperature is lower at night. Although there is a lunar halo, there may not be enough water vapor. It will be heated and expanded before noon to form a cool breeze.

These proverbs are very useful.
