Is it the same as the eight-character solar calendar or lunar calendar?

Reason: It is neither a solar calendar nor a lunar calendar, but a dry calendar, combining yin and yang. This calendar has been used since the ancient Yanhuang period, and it is the longest used calendar in China. Ancient almanac is generally marked in lunar calendar and dry calendar. When calculating the horoscope, whether it is a solar calendar or a lunar calendar, it must be converted into a dry calendar for calculation.

Therefore, it doesn't matter whether you use the solar calendar or the lunar calendar.
