Free Sun Sign Calculator
Find your Sun sign in seconds with our free online Sun sign calculator. Enter your birth details and see which zodiac sign the Sun was in when you were born, plus what it says about your core personality, motivation, and strengths.
What Is a Sun Sign?
Your Sun sign is the zodiac sign the Sun was moving through at the moment you were born. In astrology it represents your core identity: your basic character, your drive, your ego, and the way you shine in the world. It is the sign most people mean when they say “I’m a Leo” or “I’m a Pisces.”
Your Sun sign is the foundation of your birth chart, but it is only one part of it. Your Moon sign describes your emotional nature and your Rising sign describes how others first see you. Together they give a much fuller picture than the Sun alone.
How to Find Your Sun Sign?
There are three simple ways to find your Sun sign:
- Use the calculator above. Enter your birth date (adding birth time and city helps if you were born near the edge of a sign) and the calculator shows your exact Sun sign instantly.
- Check the date ranges below. Find the range that includes your birthday.
- Look at your birth chart. The Sun’s position is listed in every natal chart. You can generate a full chart with our [Birth Chart Calculator].
How to Calculate Your Sun Sign?
The Sun appears to travel through all 12 zodiac signs over one year, spending roughly 30 days in each. To calculate your Sun sign, you find where the Sun was on your birth date. The quickest way is the table below, but the exact day a sign starts changes slightly from year to year and depends on your time zone.
Sun Sign Dates (Tropical Zodiac):
- Aries: March 21 – April 19
- Taurus: April 20 – May 20
- Gemini: May 21 – June 20
- Cancer: June 21 – July 22
- Leo: July 23 – August 22
- Virgo: August 23 – September 22
- Libra: September 23 – October 22
- Scorpio: October 23 – November 21
- Sagittarius: November 22 – December 21
- Capricorn: December 22 – January 19
- Aquarius: January 20 – February 18
- Pisces: February 19 – March 20
These are the commonly used dates. The exact start and end can shift by a day, which is why our calculator uses your precise birth details instead of a fixed table.
Born on the Cusp?
If your birthday falls on the first or last day of a sign, you may have heard you are “on the cusp.” The Sun changes signs at a specific moment, not at midnight, so on those days your birth time and birth place decide which sign you actually are. Someone born in the morning could be one sign, and someone born that evening on the same date could be the next.
If you are unsure, enter your exact birth time and city into the calculator. It will tell you the correct sign for your moment of birth.
Tropical vs Sidereal: Why Your Sun Sign Can Differ?
Western astrology uses the tropical zodiac, which is based on the seasons, and the dates above follow it. Vedic (Indian) astrology uses the sidereal zodiac, which is based on the fixed stars. The two systems are about 24 degrees apart, so for most people the Vedic Sun sign is the one before their Western Sun sign. If you were told you are a different sign in Vedic astrology, this is why. Neither is a mistake; they are two different systems.

Frequently Asked Questions
What is my Sun sign?
Your Sun sign is the zodiac sign the Sun occupied on your birth date. Enter your details into the calculator above to find it instantly.
How do you find your Sun sign?
Use the free calculator on this page, or match your birthday to the date ranges listed above. If you were born close to a sign change, use the calculator with your birth time and city for an exact result.
How accurate is this Sun sign calculator?
The calculator works out the Sun’s actual position at your birth using astronomical calculations, so it is more precise than a simple date chart. Results follow the tropical zodiac used in Western astrology.
Is my Sun sign the same as my zodiac sign?
Yes. When people say “zodiac sign” they almost always mean their Sun sign. Your full chart also contains your Moon sign, Rising sign, and the positions of the other planets.
Can my Sun sign change?
No. Your Sun sign is fixed by the moment of your birth. What changes is where the Sun is today: each year it moves through all 12 signs, which is why we talk about “Leo season” or “Pisces season.”
Do I need my birth time to find my Sun sign?
For most birthdays, the date alone is enough. Birth time only matters if you were born on a day when the Sun changes signs.
Why is my Sun sign different in Vedic astrology?
Vedic astrology uses the sidereal zodiac, which places the Sun about 24 degrees behind the tropical position. For most people this means a different sign, usually the previous one.
What is the difference between a Sun sign and a birth chart?
A Sun sign is one placement. A birth chart maps the Sun, Moon, all the planets, and the twelve houses. Get the full picture with our [Birth Chart Calculator].
Is this Sun sign calculator free?
Yes, completely free to use online, as often as you like.
