How Your Zodiac Sign Is Determined
Your zodiac sign is set by the position of your birth date within the twelve sign date ranges that divide the year. Enter your birth date above and the calculator matches its month and day to the sign whose range contains it.
For example, someone born on April 15 falls in the Aries range (March 21 to April 19), while someone born on October 25 falls in the Scorpio range (October 23 to November 21). Only the month and day matter — the year does not change your sign.
If you want the exact age that goes with that birth date, try the age calculator.
To check which weekday you were born on, use the day of week calculator.

Worked Examples
Example 1 — Birth date 1990-04-15. April 15 lies between March 21 and April 19, so the sign is Aries. Aries is a Fire sign, and its traditional traits are bold, energetic and direct.
Example 2 — Birth date 2026-10-25. October 25 lies between October 23 and November 21, so the sign is Scorpio. Scorpio is a Water sign, and its traditional traits are focused, loyal and intense.
Example 3 — Birth date 2000-01-05. January 5 lies between December 22 and January 19, so the sign is Capricorn, an Earth sign. Note that Capricorn is the only sign whose range crosses the new year, which is why it appears at both ends of the calendar.
The Four Elements
Each sign belongs to one of four elements — Fire, Earth, Air or Water — and each element groups three signs that traditionally share a similar character.
| Element | Signs | Traditional character |
|---|---|---|
| Fire | Aries, Leo, Sagittarius | Energetic, passionate and action-oriented. |
| Earth | Taurus, Virgo, Capricorn | Practical, steady and grounded. |
| Air | Gemini, Libra, Aquarius | Social, thoughtful and idea-driven. |
| Water | Cancer, Scorpio, Pisces | Emotional, intuitive and caring. |
Boundary Dates and What Signs Do Not Decide
If your birth date falls exactly on a boundary date, such as March 21 or October 23, use the range as written: March 21 is Aries and October 23 is Scorpio. The ranges in the table above are the standard ones used by this calculator, with no overlap between neighbouring signs.
Zodiac signs are a traditional system of personality descriptions, not a scientific measurement. Treat the traits as entertainment and self-reflection, not as a prediction about health, money or relationships.
