Why do fortune tellers use the lunar calendar to tell their fortune?

In fact, ancient people's fortune-telling was based on the horoscope, also known as the four-poster constellation-that is, heavenly stems and earthly branches was used to express the year, month, day and time.

Heavenly stems and earthly branches actually originated from the concept of astronomy. Furthermore, the number of earthly branches is 12, which is exactly 1 1.6 years when Jupiter orbits the sun. If the influence of the earth's revolution is added, it is exactly 12 years.

In addition, Saturn orbits the earth once every 29.5 years. Plus the influence of the earth's revolution, it will be 30 years.

Therefore, the minimum common divisor of Jupiter and Saturn's revolution around the sun is 60- heavenly stems and earthly branches combination number, which happens to be 60 Jiazi.

Let's take Rizhu as an example.

The sun column expresses the influence of the moon's revolution around the earth, which will of course involve the changes of people and everything, and this is actually the real reason why the ancients believed that the horoscope can tell fortune.

It can even be said that although the "eight characters" are only time on the surface, they are actually the result of astronomical observation-expressing space in time and locating the influence of several large celestial bodies on people (from birth to death).

The implication is that in the ancient people's cognition, "eight characters" is like a naturally formed geomantic field reaching the celestial scale. It always affects people's internal environment, such as internal emotions, interests, willpower, and even looks.

This is the main reason why the ancients used the lunar calendar to tell fortunes.
