How to remember the time of the twelve constellations

It is not difficult to remember the time of 12 constellation.

Because the earth revolves around the sun once a year, it is divided into four seasons: spring, summer, autumn and winter. The days of the four seasons are:

Vernal equinox -3/2 1- the beginning of Aries

Summer solstice -6/2 1- the beginning of cancer

September 22nd Autumnal Equinox-the beginning of Libra

Winter solstice-12/2 1- the beginning of Capricorn

12 constellation four seasons division method is:

Spring: Aries, Taurus, Gemini

Summer: Cancer, Leo, Virgo

Autumn: Libra, Scorpio, Sagittarius

Winter: Capricorn, Aquarius, Pisces.

A year 12 months is divided into four seasons, and each season has three months, which is exactly one month for a constellation. As long as you remember the three constellations of each season and the dates of vernal equinox, summer solstice and autumn solstice, you can calculate the period of each constellation. For example, the three constellations in spring are Aries, Taurus and Gemini. Aries starts at the vernal equinox of 3/2 1, then Taurus starts at 4/2 1 and Gemini starts at 5/2 1.

Therefore, the derivation algorithm is correct:

Aries 3/2 1 vernal equinox 3/2 1

Taurus 4/265438

Gemini 5/265438

Cancer 6/2 1 summer solstice begins

Leo 7/2 17/22

Virgo 20 12 August 26th

Libra's autumnal equinox on September 22nd begins on September 22nd.

Scorpio 10/22 10/23

Sagittarius11/221/22

Capricorn 12/2 1 winter solstice121

Aquarius 1/2 1 1/20

Pisces 2 12/ 19

As for the discrepancy between the deduction algorithm and the correct time, I will try to adjust it myself.

However, because the earth revolves around the sun, the solar calendar returns to a slightly different position in a year. There may be a day difference between the vernal equinox, the summer solstice and the autumn solstice, so you need to check the astronomical calendar to get the correct time.

Constellation relativity adopts the view that when two constellations are critical, they will be influenced by both constellations at the same time. If the critical point of the algorithm is pushed away, it will be influenced by the other constellation.
