Compare any two Chinese zodiac signs — or two birth dates — for romance, friendship, and business scores. The checker uses traditional earthly-branch relations (San He, Liu He, Liu Chong, Liu Hai) plus five-element harmony, then links you to a full pair guide.
Classic Chinese astrology groups the 12 earthly branches into alliances and oppositions. San He (三合) is a three-sign trine that shares long-term goals. Liu He (六合) pairs are the strongest one-to-one matches, often called secret friends. Liu Chong (六冲) is a direct clash; Liu Hai (六害) warns of hidden friction. Our scores weight these relations differently for love, friendship, and business.
Your Chinese zodiac sign follows the lunar year, which begins at Lunar New Year — not 1 January. People born in January or early February often belong to the previous animal. Use birth-date mode so the converter maps the Gregorian date to the correct lunar zodiac year before scoring.
Chinese zodiac compatibility is rooted in ancient Han Dynasty astrology and Yin-Yang Five Elements theory (五行). Ancient scholars classified the 12 Earthly Branches (地支) into harmonious triangular alliances (San He / 三合), intimate secret friend pairs (Liu He / 六合), and opposing clash directions (Liu Chong / 六冲). For over two millennia, these astrological principles guided matrimonial arrangements, business alliances, and interpersonal diplomacy across East Asian cultures.
