Generally the Sun is in the Sagittarius constellation from 22nd November to 20th December, although depending on the year the Sun can move into Sagittarius either a day earlier or later.
Sagittarians are ruled by Jupiter, the planet of luck and joviality. They are optimistic and sincere with an insatiable thirst for exploration. Cherishing freedom and aiming high, they hate detail and hypocrisy – they need to learn to be more disciplined.
