The most frequently asked question in astrology is “What’s your sign?”. This question actually refers to your Sun sign: the sign the Sun was in at the moment you were born is your “Sun sign.” The Sun sign describes the core of your personality, your life force, your willpower, how you step into the spotlight, and why you are ‘that person’ in this life.

Astroappy’s tools primarily use the tropical system as a basis; if you would like to discover your counterpart in the Vedic system, you can also use the Vedic Birth Chart section.
