The years from the first day of the first month of that year to New Year's Eve of the following year are all "non-cloudy years".
meaning
Calendars are not commonly used, but calendars are mostly used for numerology. Therefore, it is based on the solar term month, not the new moon, which is different from the Gregorian calendar year based on the lunar year. In fact, the year of "Ganzhi" which has been widely circulated in recent years began in beginning of spring that year. This is a numerology view, not a common folk practice. Lunar calendar is a dry calendar, and solar terms are used to guide agricultural production. Branches and branches are not divided into solar terms, regardless of traditional habits or official calendars.
