大暑是二十四节气中的第十二个节气，也是夏季的最后一个节气。每年公历7月22日或23日，当太阳到达黄经120°时为大暑。"大暑"意为炎热之极，是一年中最热的时期。大暑正值中伏前后，我国大部分地区进入一年中最热的时期，高温酷暑，气温可达40度左右。民谚有"小暑大暑，上蒸下煮"之说，形象地描述了这个时节的炎热程度。大暑时节，阳气达到顶峰，万物生长到极致，同时也预示着夏季即将结束。虽然酷热难耐，但这也是农作物生长最快、最需要水分的时期，对农业生产至关重要。大暑节气的到来，标志着我国大部分地区进入一年中最炎热的季节。

Major Heat (Dashu) is the 12th solar term among the 24 solar terms and the last solar term of summer. It occurs annually on July 22nd or 23rd when the sun reaches 120° celestial longitude. "Dashu" means extreme heat, marking the hottest period of the year. Major Heat falls around the middle of the "Dog Days" (Sanfu), when most parts of China experience the year's highest temperatures, which can reach around 40°C (104°F). A folk saying goes: "Minor Heat and Major Heat, steaming above and boiling below," vividly describing the intense heat of this period. During Major Heat, yang energy reaches its peak and all things grow to their fullest, while also signaling that summer is coming to an end. Although the heat is unbearable, this is when crops grow fastest and need the most water, making it crucial for agricultural production. The arrival of Major Heat marks when most of China enters the hottest season of the year.
