The year of the Rat is counted from beginning of spring in the twenty-four solar terms, because the year of the Zodiac is attached to the calendar year of the main branch, and the calendar year of the main branch is the calendar year method of the main branch. The same is true of the official almanac of past dynasties (that is, the Yellow Calendar). There is no doubt that the lunar calendar only uses branches to mark the year, which ranges from the first day of the first month to New Year's Eve.

Lunar calendar and trunk calendar are two different calendars, which are different in the starting point of a year, the division rules of months and the number of days in each year. Due to the use of the Gregorian calendar after the Republic of China, many people, including a few so-called experts, lack calendar knowledge, so the two are often confused.
