Birth Sign Calculator
Your birth sign, also known as your zodiac sign or Sun sign, is one of the most recognized parts of astrology. It is determined by the position of the Sun on the date you were born and is often associated with your personality, strengths, communication style, and general outlook on life. Whether you’re curious about your own zodiac sign or checking someone else’s, a Birth Sign Calculator provides quick and accurate results.
Our Birth Sign Calculator makes it easy to determine your zodiac sign by simply entering your birth date. In addition to identifying your birth sign, the calculator also provides useful information such as your zodiac element, modality, ruling planet, birth sign dates, and a brief overview of common personality characteristics associated with that sign.
This tool is suitable for beginners, astrology enthusiasts, and anyone interested in learning more about the zodiac.
What Is a Birth Sign Calculator?
A Birth Sign Calculator is an online astrology tool that determines your zodiac (Sun) sign using your date of birth.
The calculator compares your birth date with the standard zodiac date ranges and identifies which of the twelve zodiac signs the Sun occupied on the day you were born.
Unlike a full birth chart calculator, this tool focuses specifically on your Sun sign, making it simple and fast to use.
How Does a Birth Sign Calculator Work?
The calculator checks your birth month and day against the standard zodiac calendar.
Each zodiac sign corresponds to a specific date range during the year. When you enter your birth date, the calculator identifies the matching sign and displays related astrological information.
No birth time or birthplace is required because the Sun sign is determined primarily by the calendar date. However, individuals born very close to the date when the Sun changes signs (often called the “cusp”) may wish to use a complete birth chart calculator for greater precision.
Zodiac Sign Date Ranges
The calculator uses the following commonly accepted zodiac date ranges:
| Zodiac Sign | Date Range |
|---|---|
| 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 |
Inputs Required
The Birth Sign Calculator requires only one input:

- Compare the month and day with the zodiac date ranges.
- Determine the matching zodiac sign.
- Display the associated astrological information.
For example:
- Birth Date: April 10
