How to choose to move on auspicious day?

People often ask: Is the auspicious day really meaningful? If so, how to calculate?

To understand this problem, we must first understand some basic concepts.

The first concept: What is the ecliptic?

The Chronicle of Hanshu contains: "The ecliptic is a light path." The ecliptic is the light path and track of the sun. Traditionally, the ancients used the constellation that the sun passed once as a reference to record its position, which was called the ecliptic.

The familiar twenty-eight nights, ten days, twelve earthly branches and twelve constellations are actually synonymous with the ecliptic.

The second concept: what is "Ji"?

The so-called "auspicious" in ancient astronomy is sunny; The so-called "fierce" means rainy days.

The third concept: What is a "day"?

According to our understanding today, the sun means either the sun or a day. But in ancient times, the word "day" in some places had other meanings. For example, the famous legend Houyi Shoots the Sun says that "there are ten days in the sky". People understand that there are ten suns in the sky, but in fact this means ten days of dryness.

On a certain day in a month that we often contact, "month" does not refer to the moon, and "day" does not refer to the sun. Both the day and the month represent a scale grid that divides the ecliptic. Then "10th" means dividing the ecliptic into ten squares, and "December" means dividing the ecliptic into twelve squares.

Then "auspicious day on the zodiac" literally means those sunny parts of the zodiac in a year.

Understand the meaning of "auspicious day", let's take a look at some traditional sayings:

"Qinglong, Tang Ming, Jingui, Tiande, Yutang and Siming" are called the six zodiac signs, and the days when these six gods are on duty are called auspicious days of the zodiac. Everything goes well, not avoiding evil spirits, good luck; "White Tiger, Heaven Punish, Suzaku, Tianlong, Xuanwu and Gouchen" are collectively called the six underworld gangs, which are evil spirits and unlucky criminals.

The Book of Rites and the Moon Order states: "The month is in midsummer, and the day is in Wei Xiao. In the mid-autumn moon, the sun is in the corner. "

Let's look at the distribution of the twelve evil spirits again, and we will find that Qinglong is where the autumnal equinox is, and White Tiger is where the vernal equinox is. The so-called six "ecliptic days" are distributed between the autumn equinox and the spring equinox; The so-called six "Mafia Days", five are distributed between the vernal equinox and the autumnal equinox, and one is distributed between the winter solstice and the beginning of spring.

The vernal equinox and autumnal equinox are the dividing lines between dry season and rainy season. The rainy season begins at the vernal equinox and ends at the autumnal equinox.

In other words, the so-called "Six Zodiac Day" originally refers to the period of a year when the rainfall is relatively small, and there are naturally more sunny days, so outdoor activities such as sacrifice, marching and construction are more suitable.

The so-called "Six Mafia Days", in which five days are located at the time of relatively heavy rainfall and rainy weather in a year, is not suitable for all kinds of outdoor activities. The special one is Xuanwu, which is also in the dry season, but during the winter solstice to beginning of winter, the cold air gathers and freezes for three feet, that is, "three or nine days". The winter vacation also brings inconvenience to various outdoor activities, so it is designated as Mafia Day.

On the whole. "auspicious day" still has certain basis and reason. When we choose, we should try to choose after the autumnal equinox and before the vernal equinox, and avoid three or nine days in the middle.
