When is the Cold Food Festival?

The Cold Food Festival is on the 105 day after the solar term from summer solstice.

The Cold Food Festival is from summer to the future 105, one or two days before Tomb-Sweeping Day. The first day is a holiday, smoking is forbidden and only cold food is eaten. In the development of later generations, customs such as sweeping, walking, swinging, cuju, holding hooks and fighting cocks gradually increased.

The Cold Food Festival, which lasted for more than 2,000 years, was once known as the largest folk festival in China, and it was the only festival named after the food custom among the traditional festivals in China. The Cold Food Festival is an important festival in the history of China, which originated from the story of ancestor worship, followed by mesons. Cold Food Festival, also known as "No Smoking Festival", "Cold Food Festival" and "Hundred Five Days Festival", follows the ancient habit of changing fire. In early spring every year, the climate is dry, not only the kindling preserved by people is easy to cause fire, but also the occurrence of spring thunder is easy to cause mountain fires. In this season, the ancients held a grand sacrificial ceremony to put out all the kindling handed down from the previous year, that is, "forbidding fire", and then drilled a new fire as the starting point of production and life in the new year, which was called "changing fire" or "inviting new fire". When the fire is changed, a grand ritual activity is held to burn the symbol of millet, the god of cereal, which is called human sacrifice. After the custom was passed down, it formed the later No Fire Festival. There is an interval between banning fire and changing fire. Historical materials have different opinions such as three days, five days and seven days.
