How did the fortune teller calculate it?

Fortune tellers in China tell fortunes according to the lunar calendar.

The lunar calendar is not a lunar calendar or a solar calendar, but a combination of yin and yang.

The month of the lunar calendar belongs to the lunar calendar, because the number of days in a month is set according to the cycle of the moon orbiting the earth.

The year of the lunar calendar belongs to the solar calendar, because the average number of days in a year is set according to the cycle of the earth's orbit around the sun. And the 24 solar terms of the lunar calendar are also solar calendars.

Fortune tellers usually regard beginning of spring as the beginning of the first month, fright as the beginning of February, and Qingming as the beginning of March ... This is according to the solar calendar. Sometimes, we also refer to the moon's profit and loss and the date of the lunar month, which is also based on the lunar calendar.

So, according to the lunar calendar.

The solar calendar mentioned above has nothing to do with the Gregorian calendar.
