Why does it always rain on Mid-Autumn Festival?

Because the Millennium solar terms have the implication of widening temperature difference between day and night and increasing dew condensation, the Millennium solar terms also indicate the beginning of autumn.

There is a proverb circulating in the countryside about the Millennium solar terms, "Singles Day is celebrated in the Millennium, and the underground is not dry". In other words, this day of the Millennium solar terms coincides with the single day or double day of the lunar calendar, which has a certain predictive effect on the next weather. If the Millennium solar terms catch up with a single day, it indicates that it will rain later and will not dry on the ground because of frequent rain.

As the saying goes, it rained on August 15th, and it rained repeatedly for forty-five days. The 15th of August mentioned here is also the Mid-Autumn Festival, which means that once it rains, it may rain for forty-five consecutive days, which is equivalent to a month and a half without good weather. This exaggeration is also used to remind people of future weather changes.

202 1 Millennium solar terms

The Millennium solar term of 202 1 coincides with the first day of the eighth lunar month, which means that the Millennium solar term has caught up with a single day, indicating that it may be rainy this autumn. Looking back now, this proverb in the countryside has long given a warning. At present, there is continuous rainfall in many places, which also confirms that this proverb still has some truth.

The arrival of the summer solar term means that the midsummer season is coming to an end and the temperature will gradually drop. In the summer solar term, there is a saying in the countryside that "the head is drenched in midsummer, and the eighteen rivers are full", which is easy to understand. In other words, once it rains and gets wet on the day of the summer solar term, it often rains more.
