The order of the twelve constellations, such as the birthday of Pisces or Scorpio.

The specific order of the twelve constellations is Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius and Capricorn.

Pisces is the last one, so Scorpio has a big birthday.

China, however, traditionally ranks from one to twelve.
