What your birth chart shows
Your Sun sign is your core identity, the you that stays constant. YourMoon sign is your inner, emotional world, and your rising sign(ascendant) is the first impression you give and how you approach anything new. Together these three, often called your "big three", are the heart of your chart. Beyond them, each planet sits in a sign and a house, adding detail to areas like communication (Mercury), love (Venus), and drive (Mars). This tool calculates all of it from real astronomical positions, using the tropical zodiac and whole-sign houses.

Birth chart FAQ
What is a birth chart?
A birth chart (or natal chart) is a snapshot of the sky at the exact moment and place you were born. It maps where the Sun, Moon, and planets sat across the twelve zodiac signs and houses, and astrologers read it as a portrait of your personality and life themes.
What do I need to calculate my chart?
Three things: your birth date, your birth time (as exact as possible), and your birth city. The date sets your Sun sign, and the exact time and place are what pin down your rising sign (ascendant) and house placements.
What is a rising sign?
Your rising sign, or ascendant, is the zodiac sign that was climbing over the eastern horizon at your birth. It changes roughly every two hours, so it needs your exact birth time. It is often described as the first impression you give and how you meet the world.
Is my birth information private?
Yes. The entire chart is calculated in your browser using open astronomical formulas. Your birth date, time, and location are never sent to a server or stored anywhere.
What if I do not know my birth time?
You can still get an accurate Sun and Moon sign and all planetary placements. Your rising sign and houses need an exact time, so tick "I don’t know my exact time" and those will be marked as needing your birth time.
