Zodiac Calculator

The Zodiac Calculator is a web tool that instantly calculates the Chinese zodiac (Eto) for any given year. The Eto system combines 12 Earthly Branches (Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, Boar) with 10 Heavenly Stems (Wood Yang/Yin, Fire Yang/Yin, Earth Yang/Yin, Metal Yang/Yin, Water Yang/Yin) to form a 60-year cycle used in Chinese and Japanese calendrical systems for centuries.

This tool displays the kanji, reading, animal name, and emoji for the Earthly Branch, plus kanji, reading, and Five Element (Wood, Fire, Earth, Metal, Water) for the Heavenly Stem, and the sexagenary cycle number (1-60). Each Heavenly Stem carries both an element and Yin/Yang polarity, revealing the deeper nature of each year in the cycle. This deeper understanding helps you connect with traditional East Asian philosophy and astrology.

Use it for New Year's card zodiac checks, birth year zodiac lookups, identifying historical year zodiacs, or learning about Chinese and Japanese calendrical traditions. All processing is done in your browser — no data is sent to any server, ensuring your privacy.
