Know your astrology sign
Your Sun sign is the heart of your chart. Enter your date of birth and find it in a second, with the logic behind it. No birth time, no sign-up.
What is your astrology sign?
Your astrology sign, also called your star sign or Sun sign, is simply the zodiac sign the Sun was sitting in on the day you were born. The Sun takes a year to travel through all twelve signs, spending about a month in each, so your birthday lands you squarely in one of them. It is the sign you reach for when someone asks "what's your sign?", and it describes the core of who you are: your identity, your drive, and the way you naturally want to shine.
How the sign checker works
This tool needs one thing only: your date of birth. Because the Sun moves through the zodiac on almost the same schedule every year, your day and month are enough to pin down your sign with no birth time or birthplace required. Type your date above and the checker matches it against the twelve sign date ranges and returns your sign right away, along with its element, its ruling planet and a plain-English summary of what it means.
Your Sun sign is the headline, not the whole story
Here is the honest part most quizzes skip. Your Sun sign is one placement out of roughly thirty in a full birth chart. Your Moon sign shapes your emotions and what makes you feel safe. Your Rising sign shapes the first impression you give. Every planet sits in its own sign and house, pulling your personality in its own direction. That is why two people born under the same star sign can feel completely different. The Sun is where you start, not where the story ends, so once you know your sign, cast your free birth chart to read the rest.

Born on the cusp?
If your birthday falls on the day one sign changes to the next, you might have heard you are "on the cusp" of both. In practice, real astrology puts you in one sign or the other, never two at once. The catch is that the exact moment the Sun changes signs can shift by a few hours from year to year, so a birthday right on the boundary can genuinely belong to either sign depending on the year and your birth time. If the checker flags your date as borderline, the surest way to settle it is to cast a full chart with your exact birth time.
Astrology sign questions, answered
Enter your date of birth in the checker above and it instantly matches your day and month to one of the twelve zodiac signs. That is your Sun sign, also called your star sign. You do not need your birth time or place, just the date.
The Sun spends about a month in each sign every year, on almost the same dates, so your birthday alone is enough to find your sign. The checker compares your date against the twelve sign date ranges and returns the match, along with its element, ruling planet and a plain-English summary.
If your birthday falls on the day one sign hands over to the next, the exact result can depend on the year and your birth time, because the moment the Sun changes signs shifts by a few hours each year. The checker flags you as borderline when this happens. To be certain, cast a full birth chart with your exact birth time and we work out the rest.
Your Sun sign is just one of around thirty placements in your chart. To go further, use the Moon Sign Calculator for your emotional inner world and the Rising Sign Calculator for the impression you give, then cast your free birth chart to see every planet in one place.
For your Sun sign it is reliable, because the Sun moves slowly and predictably through the year, so the date is enough. Birth time only changes the answer if you were born right on a sign boundary. For your Moon, Rising and house placements, though, you do need an accurate birth time.
