According to the lunar calendar or the solar calendar?

Tai sui is based on the lunar calendar, because the lunar calendar is also a calendar invented by our ancestors according to the periodic law of the moon and combined with all agricultural activities. All kinds of fortune-telling or chronicles are calculated according to the lunar calendar. Tai sui is a 60-year-old flower, which varies from year to year and circulates once every 60 years. So Taisui Yue looked at it according to the lunar calendar instead of the solar calendar.
