"The solar calendar follows the sun, and the lunar calendar follows the moon." This statement is not accurate. No matter what calendar it is, it cannot be separated from the sun. The solar calendar is derived based on the movement patterns of the yellow-red intersection angle between the sun and the earth. Yes, the earth also changes seasons as the angle between yellow and red changes; the lunar calendar is the traditional Chinese calendar, also called the lunar calendar, which is closely related to the traditional agricultural society. In ancient times, the calendar was accurately calculated using the maximum direct angle of the sun and the moon phase. Both They are all related to the sun, but the error of the lunar calendar is slightly larger than that of the solar calendar. For example, the arrival of the twenty-four solar terms is generally measured and calibrated according to the solar calendar. The biggest feature of the lunar calendar is that the tides are closely related to the gravitational pull of the moon (related to changes in solar terms), and the moon will be round on the 15th day of the year...

"It rains at midnight in the sun's halo, and there is wind at noon in the moon's halo"

"Halo rain in the middle of the night": The sun is extremely hot during the day, but it still produces a corona, which means that the water vapor is quite moist. At night (the temperature is the lowest in the middle of the night), rain will inevitably occur;

"Moon halo noon wind" is opposite to the solar halo. The temperature is relatively low at night. Although there is a moon halo, the water vapor may not be sufficient. Before noon, it will be heated and expand, forming a cool wind.
