Capricorn is the tenth of the twelve signs of the zodiac, and is usually represented as a sea goat. People born from 22 December until 19 January fall under this sign.

Horoscopes are officially just supposed to be the star constellation which is directly overhead when you're born, but if you're one of the people who also thinks they have something to do with predicting your future, there's a good teen-specific daily horoscope here.
