Sun Sign Calculator
Enter your birth date to find your tropical zodiac Sun sign. The result includes the sign date range, element, modality, cusp notes, and a focused read on core identity and motivation.
What your Sun sign shows
The Sun sign points to identity, vitality, creative direction, and the qualities you consciously develop.
Why cusp dates need care
The Sun changes signs at an exact moment, not at midnight in every time zone. Birth time and location matter near boundaries.
What to calculate next
After the Sun, compare the Moon and Rising signs for emotional needs and first-impression style.
How to use your Sun sign result
Treat the Sun sign as the center of the chart, not the whole chart. It describes what gives you energy, how you tend to shine, and the identity themes you return to when making decisions.
For a fuller chart-style read, compare this result with the Sun Moon Rising sign calculator, Venus sign calculator, and Juno sign calculator.
Frequently asked questions
Is my Sun sign the same as my zodiac sign?
Usually, yes. In everyday astrology, zodiac sign often means Sun sign: the tropical zodiac sign where the Sun was placed when you were born.
Do I need my birth time to calculate my Sun sign?
Most people can identify their Sun sign from birth date alone. Birth time and birth location matter most if you were born on or very near a date when the Sun changed signs.
What if I was born on a cusp date?
If your birthday is close to a sign boundary, use the result as an educational estimate. Exact Sun sign near a boundary requires a full ephemeris calculation using the birth time, geographic location, and historical time zone rules.
What does the Sun sign mean in astrology?
The Sun sign describes core identity, vitality, motivation, creative self-expression, and the qualities you tend to grow into over time.
Is this a complete birth chart calculator?
No. This page focuses on the Sun sign. A complete birth chart also includes the Moon, Rising sign, planets, houses, aspects, and precise chart angles.
