Where do you rank today,
out of 1,080?

Your birthday

Two people with the same zodiac sign do not have the same day. In Japanese fortune-telling, the day you were born also has a day-stem (one of ten) and a star (one of nine). 12 signs × 10 stems × 9 stars = 1,080 combinations, and this site ranks all of them, every day. Enter your birthday and see where you stand today. Your birthday never leaves this browser: it is not sent to any server, and it is remembered on this device only so you don't have to type it again (you can forget it any time).

Your day, out of 1,080Your rank, a one-line reading, and your sign's rank among the 12. Short enough to read on the train.

How the ranking is made

The twelve zodiac signs are ranked every evening (21:00 Japan time) from the positions of the planets, computed from NASA/JPL's ephemeris, combined with two public signals about the world that day: the mood of the markets (economic climate) and the state of the Sun and Earth's magnetic field (space weather). Your day-stem and star are then read against the day's stem and star using classical Japanese and Chinese rules (Four Pillars, Nine Star Ki), which spread each sign's 90 people across the 1,080 ranks.

This is a Japanese site; the daily readings, archives back to 1990, compatibility pages and articles are in Japanese. Modern browsers translate them well. Fortune is meaning, not prediction: we publish how the ranking is built, and we don't claim it predicts anything.
