Check the constellation according to the lunar or solar calendar.

Like the western world, the twelve constellations are calculated according to the solar calendar, that is, according to the date of birth on your ID card. If the date on the ID card is incorrect, it is calculated according to the solar calendar of your date of birth. Because our constellation is said to be western, many theoretical foundations are based on the west, so the other side is based on the solar calendar. In order to make our constellation results more accurate, we have to follow the solar calendar. The new calendar is the solar calendar.

What is the solar calendar?

Gregorian calendar, also known as Gregorian calendar or new calendar, is an internationally recognized date calendar. From an astronomical point of view, it is a calendar calculated according to the annual movement of the sun, with 365 days in a year. According to the operating cycle of the direct point of the sun, the general calendar year is tropic, and there are two kinds of calendar years, one is a normal year, the other is a leap year, and the leap year is only one day away from the normal year. This kind of solar calendar is universal all over the world, so it is also called solar calendar.

The origin of constellations

The origin of the constellation is Babylon, one of the four ancient civilizations in China. At that time, they divided the sky into different regions and called them "constellations", which is the origin of constellations. Then the Babylonians made a long-term observation of these "constellations", determined the ecliptic through constant observation, and finally divided it into twelve parts, so the "zodiac signs" appeared. The end result is that the zodiac signs are named after each other. Starting from the vernal equinox, counterclockwise is Aries (Aries), Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius (Sagittarius), Capricorn, Aquarius (Aquarius) and Pisces.

So because birthdays in the western world are calculated by the solar calendar, constellations still have to be calculated by the solar calendar. And your sign is the place where you were born when the sun passed through the zodiac, and that is your personal sign.
