Chinese zodiac, BaZi and Zi Wei Dou Shu, written in plain English — with the method shown rather than hidden.
Most English-language material on Chinese astrology is either a personality quiz or a wall of transliterated terms. ZodiacRune sits in between: real systems, real calendar mechanics, explained so that you can check the reasoning yourself.
The zodiac animal is the part everyone knows, and it is one character out of eight. The rest of the site exists to show what the other seven do, and why two people born in the same year can read very differently.
The calculator on the home page applies all four boundaries, then derives the Day Master, the ten gods, the element balance and eight ten-year luck pillars. You can read the logic in the BaZi section and check any step against a printed calendar.
