♐ Your birth constellation: Sagittarius
Traditional dates: November 22 – December 21
Sagittarius lies in the direction of the center of our Milky Way galaxy. When you look at Sagittarius, you are looking toward the supermassive black hole Sagittarius A*, which has a mass of about 4 million suns. The constellation contains more Messier objects (star clusters and nebulae) than any other, making it a favorite target for amateur astronomers. The "Teapot" asterism within Sagittarius is one of the easiest star patterns to spot.
The zodiac system was created by Babylonian astronomers around 500 BCE as a coordinate system for tracking the Sun, Moon, and planets along the ecliptic. The twelve signs divide the ecliptic into 30-degree segments. Due to the precession of equinoxes — a 26,000-year wobble of Earth's axis — the astrological dates no longer correspond to the actual constellations the Sun passes through. Modern astronomy treats the zodiac as a historical coordinate system, not a personality framework.

🐀 Chinese zodiac: Rat (Metal)
In the traditional Chinese calendar, 2020 is a year of the Rat with the element Metal. The Chinese zodiac (shengxiao) is a repeating 12-year cycle, with each year associated with an animal. Combined with the five elements (Wood, Fire, Earth, Metal, Water), the full cycle takes 60 years.
The Rat is the first animal in the Chinese zodiac cycle. In Chinese cultural tradition, the Rat symbolizes wealth and surplus — its character appears in many Chinese idioms about prosperity. The Rat was assigned its leading position, according to legend, because it cleverly rode on the Ox's back and jumped off first to win the Jade Emperor's race.
The Chinese zodiac is a cultural and calendrical tradition with roots stretching back over 2,000 years. It was originally tied to astronomical observations of Jupiter's roughly 12-year orbital period. While widely used in East Asian cultures for festivals, naming customs, and social tradition, it is best understood as cultural heritage rather than a predictive system.
