Sanfu and Sanjiu in 2023, these two special solar terms represent the alternation between hot summer and early autumn. The specific dates are as follows: Sanfu falls on the three Geng days after the summer solstice in the lunar calendar every year, usually in June, and Sanjiu They are respectively on the 9th, 19th and 29th days after the autumn solstice, that is, September. Specifically, the Dog Day period in 2023 will be on June 24, while the Dog Day period will be on September 7, 17, and 27. This season not only contains rich folk culture, such as eating Ruyi Cai, Jiaxing Wu Ma Cai and other seasonal delicacies, but is also closely connected with the health concept of traditional Chinese medicine, which emphasizes maintaining cool diet and appropriate activities during this period when the yang energy is strongest, such as swimming and summer camp.

Although Dog Day is a traditional festival of celebration and food, it is also closely related to climate change, which is both a challenge and an opportunity. With the development of science and technology, our understanding of this season continues to deepen. It is not only an integral part of individual life, but also an important topic in earth ecological research. In the future, with the progress of human civilization, people will be better able to cope with climate change. At the same time, the celebration and research of Dog Day and Day Nine will also show more scientific value and positive impact, promoting the adaptation and recovery of biodiversity.
