Before you go
What Is a Birth Chart?
A birth chart, also called a natal chart or astrology chart, is a snapshot of the sky at the exact moment you were born. It maps where the Sun, Moon, and planets sat relative to your place of birth, and astrologers read it as a reflection of your personality, relationships, and life direction.
The birth chart calculator uses your birth date alone for your Sun sign. Your Moon and Rising signs need your birth time and city to pin down, which is why it asks for them when you have them.
Is this birth chart calculator free?
Yes. Calculate your natal chart and see your instant Sun sign preview without entering an email or paying. The full in-depth reading unlocks with credits — sign up and your first chapters are free.
What information do I need?
Your birth date is enough for your Sun sign preview. Adding your birth time and city sharpens your Moon and Rising signs, but neither is required to get started.
What is my moon sign?
Your Moon sign reflects your inner emotional world and what you need to feel safe. It changes roughly every two to three days, so it needs your birth time to pin down accurately. The full reading calculates it for you.
What is my rising sign?
Your Rising sign, or Ascendant, is the impression others form before they know you. It shifts about every two hours, so it needs both your birth time and city. The full reading works it out and explains the gap between that mask and the real you.
Is astrology scientific?
Astrology is a symbolic and reflective system, not a scientific test. Many people use it for self-awareness, journaling, and understanding the patterns in their lives and relationships.
Is my birth date stored?
Your birth date is used to calculate your result. It is not stored unless you purchase a reading, at which point it is saved to deliver your report.
