Why is the first day of the first month in the Year of the Loong still the year of Xin Mao? After the first 13 day of the first month, the beginning of spring will be considered as an inauspicious year. Excuse me, how is this XX year calculated? Yes! I can tell you responsibly that the zodiac is calculated according to beginning of spring! Genus corresponds to the earthly branches in a year. Such as "mouse" and "ugly cow". The calendar year of the lunar calendar is based on the beginning of spring. You can look at the calendar. For example, this year's Spring Festival is before beginning of spring. On the calendar, many days after the Spring Festival, it is still the year of Xin Mao. It won't be a year until next month's spring. Therefore, it is still a rabbit from the Spring Festival this year to the twelfth day of the first month.
