1990 and 199 1 when are the specific times in beginning of spring? Specific to minutes.
Beginning of spring, as a festival, existed as early as the Spring and Autumn Period. At that time, there were eight festivals in a year, namely beginning of spring, Changxia, beginning of autumn, beginning of winter, Vernal Equinox, Summer Solstice and Winter Solstice. Only the Book of Rites and Annals of Huainanzi by Liu An in the Western Han Dynasty recorded 24 solar terms.
Before the Han Dynasty, the calendar had been changed many times. At that time, beginning of spring among the 24 solar terms was designated as the Spring Festival, which meant that spring began. This title lasted for more than 2000 years, until 19 13, when the national government officially issued a document, making it clear that the first day of the first month of the first month of each year was the Spring Festival. Since then, beginning of spring has only existed as one of the 24 solar terms, and it has been passed down to this day.
