Start of Spring and Spring Festival

立春和春節

As a solar term, Start of Spring had already entered people's lives in the Spring and Autumn Period (770-476 BC). At that time, there were eight solar terms. According to some experts, the 24 solar terms were used for the first time in books during the Western Han Dynasty (206 BC-AD 24), when the Start of Spring was set as the Spring Festival. In 1913, the first day of the first month of the lunar year was mandated as the Spring Festival.

早在春秋時期（公元前770至476年），立春節氣就進入了百姓生活。當時只有8個節氣。據專家介紹，二十四節氣的說法是在西漢時期（公元前206年至公元24年）首次在典籍中出現的，當時立春就是春節。1913年，農歷一月的第一天被定為春節。
