Your Sun sign is the zodiac sign the Sun occupied on the day you were born. It’s the placement most people mean when they talk about “their sign,” and reflects your core identity and general life direction.
What Is My Sun Sign?
Your Sun sign is based purely on your birth date, since the Sun’s position along the zodiac only shifts by about one degree per day. For most birth dates, this makes the Sun sign the easiest placement to determine accurately.
How the Sun Sign Calculator Works
Enter your birth date above. We calculate the Sun’s ecliptic longitude for that date using the Astronomy Engine library, then map it to the correct 30-degree zodiac band.
What Your Sun Sign Represents
In astrology, the Sun sign is traditionally associated with core identity, ego, and general life direction. It’s one part of a larger picture that also includes your Moon and Rising signs.
FAQ
Is my Sun sign the same as my “zodiac sign”?
Yes, when people casually say “zodiac sign” without further context, they usually mean the Sun sign.
Do I need my birth time for my Sun sign?
Usually not. Birth time matters much more for your Moon sign and especially your Rising sign. It only becomes relevant for the Sun sign if your birth date falls right on a sign-change boundary.
