How long are the three summers and nine ambushes

Three Summers and Nine Ambushes is 30 days in some years and 40 days in others.

The three ambushes, which occur between the small summer heat and the final summer heat, are the time of the year when temperatures are the highest and yet humid and sultry. The three ambushes are divided into the first, middle and last ambushes, and their dates are determined by matching the dates of the twenty-four solar terms with the dates of the stem and branch chronicles. After the "ambush", many parts of the country will enter a pattern of sustained high temperatures.

Traditional calendars state that "the summer solstice and three geng will be counted in the ambush", meaning that "from the summer solstice day" to count back, counting to the third "geng day" will begin to enter the ambush. Here the "geng day" refers to the ancient "dry calendar" with "g" in the beginning of the day. "Fu" means that the yin is forced by the yang to hide underground; it also means that the weather is too hot, it is better to be in the ambush should not be moved.

The length of the day is mainly in the difference between the middle of the day and the middle of the day. The number of days in the mid-volt is also different because of the different times of the year when the third g day after the summer solstice (the first voltaic day) occurs. The mid-volt can be as long as 10 days or as short as 20 days.
