I really want to know my birthday. 1I was in beginning of spring on the evening of February 5th, 980. Excuse me friends, are they sheep or monkeys?

China Gregorian calendar uses beginning of spring to determine the zodiac. "Lunar calendar" is a kind of "solar calendar" used in Han Dynasty. The New Year is bounded by beginning of spring, beginning of spring is the first of the 24 solar terms, and the zodiac is based on beginning of spring. The zodiac began in the beginning of spring, not on the first day of the first lunar month. The date and hour of "beginning of spring" are accurately calculated by calendar scholars according to the rotation and revolution of the earth, which has accurate scientific basis. 1February 5, 980, Hitachi Spring Day, the first day of the Gengshen lunar calendar, is a monkey.
