♋ Your birth constellation: Cancer
Traditional dates: June 21 – July 22
Cancer is the faintest of the zodiac constellations, with no star brighter than magnitude 3.5. Its most notable feature is the Beehive Cluster (Praesepe, M44), an open star cluster visible to the naked eye on clear nights. The Tropic of Cancer was named because when it was defined about 2,000 years ago, the Sun was in Cancer during the June solstice. Today, due to precession, the Sun is in Taurus at that time.
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: Horse (Metal)
In the traditional Chinese calendar, 1990 is a year of the Horse 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 Horse has been central to Chinese civilization for millennia, playing a crucial role in warfare, trade along the Silk Road, and agriculture. In Chinese art, the horse symbolizes speed, perseverance, and success. The terracotta horses in the Qin Emperor's tomb (210 BCE) demonstrate the animal's importance in Chinese culture.
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.
