♑ Your birth constellation: Capricorn

Traditional dates: December 22 – January 19

Capricornus is one of the faintest constellations in the zodiac, lying in a region ancient Mesopotamians called the "Sea" because of its many water-related constellations. The Babylonians depicted it as a goat-fish hybrid around 1000 BCE. Due to the precession of equinoxes, the Sun now passes through Capricornus about a month later than the traditional astrological dates suggest.

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: Rabbit (Wood)

In the traditional Chinese calendar, 1975 is a year of the Rabbit with the element Wood. 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 Rabbit (or Hare) is associated with the Moon in Chinese mythology — the Jade Rabbit is said to live on the Moon, pounding herbs to make the elixir of life. This legend dates back to the Warring States period (475–221 BCE) and appears in literature across East Asia, including Japan and Korea.

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.
