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.
