♈ Your birth constellation: Aries
Traditional dates: March 21 – April 19
Aries is a relatively dim constellation whose brightest star, Hamal, was important in ancient navigation. Around 2000 BCE the vernal equinox was in Aries, which is why it was considered the first sign. The Sun has not actually been in Aries during "Aries season" for over two thousand years due to the slow wobble of Earth's axis.
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: Pig (Metal)
In the traditional Chinese calendar, 1971 is a year of the Pig 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 Pig is the last animal in the zodiac cycle and represents wealth, good fortune, and honesty in Chinese tradition. The Chinese character for "home" or "family" (jia) is a roof with a pig underneath — reflecting the animal's central role in Chinese domestic life for thousands of years. In the novel "Journey to the West," the character Zhu Bajie (Pigsy) provides comic relief alongside the Monkey King.
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.
