Is the constellation based on the solar calendar or the lunar calendar of your birthday?

Maybe it has something to do with your birth date just at the intersection of constellations.

The following is a detailed explanation for you.

The division of western constellations originated from Central Asian civilization.

According to the Gregorian calendar, sometimes the constellation handover date 1-2 days is often reported incorrectly!

Therefore, the most standard constellation division should be slightly different every year, because it is divided according to the ecliptic, and when it comes to the ecliptic, it slowly begins to enter the constellation gate.

The constellations we usually talk about are the twelve constellations classified purely by date of birth. In fact, they are just the constellations represented by the sun (referred to as the Sun Constellation), also known as the Sun Constellation, which refers to the zodiac sign where the sun was when we were born.

So those who are on the handover date often don't know which zodiac they are!

In fact, according to the solar terms in China, the score is the most accurate, because their score is 12, and our score is 24.

Taurus constellation

Because April 20 is just at the junction of constellations, it is necessary to check the year of birth before calculating the lunar calendar.

These are some theories. If you don't really want to have an in-depth study of constellations, you don't need to know so much. You only need to enter the date of birth on the relevant constellation website to calculate. Finally, whether Aries or Taurus, you will have some characteristics of these two constellations.
