Is the date of the twelve constellations solar or lunar?

The twelve constellations are based on the Gregorian calendar, not the lunar calendar.

The twelve constellations are the contents of western astrology. According to the west, when a person is born, the position of the stars falls into the ecliptic, which shows a person's innate character and talent.

In the west, the twelve constellations are divided into twelve constellations, which are called twelve constellations, followed by Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces.

Extended data:

More than 2000 years ago, Greek astronomer Baccus divided the ecliptic into 12 segments to indicate the position of the sun on the ecliptic, with vernal equinox as 0 and counting from vernal equinox (that is, the ecliptic is zero), and every 30 degrees is a palace.

It was named after the main constellations contained in the palaces at that time, including Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius and Pisces. It is called the zodiac and has twelve constellations.

Babies born when the earth moves to every fraction (constellation) will always have some similar characteristics when they grow up, including behavioral characteristics. Connect these associations (rich imagination and creativity) in series to make these constellations become human beings.

Later, it increased the color of myth and became an important part of culture (mainly Greek and Roman mythology). This set of numerology has evolved and spread for at least 5000 years, and they are represented by these twelve constellations.

According to astrology, each constellation has a corresponding relationship with all aspects of human beings.
