♎ Your birth constellation: Libra
Traditional dates: September 23 – October 22
Libra is the only zodiac constellation that represents an inanimate object — a pair of scales. The ancient Greeks originally considered it part of Scorpius (the scorpion's claws). The Romans established it as a separate constellation around the time of Julius Caesar, symbolizing justice and balance. Its two brightest stars still carry Arabic names meaning "southern claw" and "northern claw."
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: Monkey (Metal)
In the traditional Chinese calendar, 1920 is a year of the Monkey 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 Monkey is one of the most culturally rich zodiac animals, immortalized in the classic novel "Journey to the West" (16th century) through the character Sun Wukong, the Monkey King. In Chinese culture, the Monkey symbolizes cleverness and playfulness. Monkey imagery in Chinese art often represents wishes for career advancement.
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.
