How the zodiac sign calculator works
This zodiac sign calculator answers the everyday question "what is my zodiac sign?" from your birth date alone. As the Sun moves through the twelve signs of the zodiac across the year, it spends about a month in each. Your birthday tells you which sign the Sun was in when you were born — your sun sign, the one most people mean by their "star sign".
The calculator also handles the cusp days, the dates when one sign hands over to the next, by checking the exact day rather than guessing. So even a birthday right on the boundary comes out correctly.
What your zodiac sign says
Each sign belongs to an element — Fire, Earth, Air or Water — and has a ruling planet, and these shape the traits it is traditionally linked with. A Leo is read as confident and warm, a Virgo as analytical and helpful, a Pisces as compassionate and imaginative. Read your sign as a playful character sketch rather than a rule. Enter your date above to see yours.
Frequently asked questions
How is my zodiac sign worked out?
From your birth date. The Sun moves through the twelve zodiac signs over the year, spending about a month in each, so your birthday decides which sign — your sun sign — the Sun was in when you were born.
What if I was born on a cusp?
On the cusp days, when one sign hands over to the next, the exact day decides. The calculator checks the precise date rather than guessing, so boundary birthdays come out correctly.
What does my zodiac sign say about me?
Each sign has an element (Fire, Earth, Air or Water) and a ruling planet, and these shape its traditional traits — a Leo as confident and warm, a Virgo as analytical, a Pisces as compassionate. Read it as a character sketch, not a rule.
Is the zodiac sign calculator free?
Yes. It is completely free, needs no sign-up and runs entirely in your browser — your birth date is never sent anywhere.
