Frequently asked questions

QWhat if I was born on a cusp?

The sun enters a new sign on a slightly different date each year (±1 day). If you were born on the boundary day, the result shows the most likely sign. For exact cusp cases, an ephemeris with your birth year and time gives a definitive answer.

QIs my sun sign the same as my star sign?

Yes — 'sun sign', 'star sign', and 'zodiac sign' all refer to the same thing: the sign the sun was transiting at the time of your birth.

QWhat is a sun sign element?

Each sign belongs to one of four elements — Fire, Earth, Air, or Water — which describes its fundamental energy and temperament.
