DoubleSign™ Calculator

Your DoubleSign is your Chinese year sign paired with your Western birth-month sign. Twelve Chinese signs and twelve Western signs make 144 unique combinations, and each one has its own character profile.

Open the DoubleSign™ Calculator and enter your birth date. It reads your Chinese sign from your birth year and your Western sign from your birth month and day, then names your DoubleSign in the form Chinese/Western, for example Dragon/Scorpio.

Enter two birth dates and the calculator compares both DoubleSigns, weighing the Chinese pairing, the Western pairing, and their elements to return a single compatibility score with a short reading. The same two signs always produce the same score.

No, and we won't pretend otherwise. But the 144 profiles and the way we pair signs aren't invented either. They are drawn from centuries of Chinese and Western astrological tradition, then written and blended by hand. Treat the score as a fun, repeatable way to compare two signs and a conversation starter, not a measurement of your relationship. Take what rings true, laugh at what does not. As they say, in every joke there is a grain of truth, and we would love for you to look for it yourself.

Each of the 144 DoubleSign profiles was written by hand, drawing on traditional Chinese and Western astrology, then blended into one character for that pairing. The compatibility logic weighs the same traditions: the Chinese sign cycle, the Western signs, and their elements. Some of it is considered interpretation and some is our own reasoned guesswork, which is exactly why we say enjoy it, and take it with a grain of salt.

There are 144, one for every Chinese and Western sign combination. You can read any profile on its own page and explore the eleven other pairings that share each sign.
