The second month of the lunar calendar is in Tomb-Sweeping Day, but why is it that every fortune-telling is in the third month of the lunar calendar in Tomb-Sweeping Day?

The lunar calendar in China is a combination of yin and yang. Tomb-Sweeping Day is the "Tomb-Sweeping Day" in China's 24 solar terms, and the solar terms reflect the solar calendar in the lunar calendar, so Tomb-Sweeping Day usually has three days, from April 4th to April 6th.

Tomb-Sweeping Day belongs to the solar calendar and generally changes from April 4th to 6th. It is not fixed on a certain day, but the most common is April 5. Because the length of a year is determined by the movement of the sun, and the 24 solar terms are also determined by the apparent position of the sun, basically the date of each solar term does not change much in a year.

The extension of solar terms sometimes makes a solar term spread from midnight to the next day; Extra leap years will also lead to changes in solar terms. Of course, no matter how the solar terms change, the date difference of the solar terms will only be within 3 days.
