Birthday astrology guide
Zodiac Signs by Birthday: Complete Date Guide
Find your Western zodiac sign from your birthday and compare all 12 date ranges and symbols. In addition, learn when your birth time, birth year, or astrology system can change the answer.
Your Western zodiac sign is usually found from the month and day you were born. For example, April 11 is Aries, April 24 is Taurus, and August 28 is Virgo. However, if your birthday falls on the first or last day of a sign, your birth year, exact time, and location may be needed to confirm when the Sun changed signs.
At-a-glance answer
Zodiac signs by birthday dates and symbols
First, use the chart below to check the commonly published date ranges for the Western tropical zodiac. Next, match your birthday month and day to the correct range. Keep in mind that the symbol, element, modality, and ruling planet are traditional astrological associations rather than scientific personality measurements.
| Zodiac sign | Birthday range | Symbol | Element | Modality | Traditional ruler |
|---|---|---|---|---|---|
| Aries | March 21–April 19 | Ram | Fire | Cardinal | Mars |
| Taurus | April 20–May 20 | Bull | Earth | Fixed | Venus |
| Gemini | May 21–June 20 | Twins | Air | Mutable | Mercury |
| Cancer | June 21–July 22 | Crab | Water | Cardinal | Moon |
| Leo | July 23–August 22 | Lion | Fire | Fixed | Sun |
| Virgo | August 23–September 22 | Maiden | Earth | Mutable | Mercury |
| Libra | September 23–October 22 | Scales | Air | Cardinal | Venus |
| Scorpio | October 23–November 21 | Scorpion | Water | Fixed | Mars / Pluto |
| Sagittarius | November 22–December 21 | Archer | Fire | Mutable | Jupiter |
| Capricorn | December 22–January 19 | Sea-goat | Earth | Cardinal | Saturn |
| Aquarius | January 20–February 18 | Water bearer | Air | Fixed | Saturn / Uranus |
| Pisces | February 19–March 20 | Fish | Water | Mutable | Jupiter / Neptune |
Born on a boundary date? Published date ranges can differ by one day because the Sun does not enter each sign at the same clock time every year. Therefore, if you were born near a changeover, use an astrology chart calculated with your full birth date, exact time, and birthplace.

How to understand cusp birthdays
*A boundary date is sometimes called a “cusp” birthday. However, in standard astrology calculations, the Sun is in one sign at a specific moment—it is not technically in two signs at once.
The 12 birthday zodiacs
Zodiac symbols and traditional meanings
Each sign has a glyph, a symbolic figure, an element, and qualities traditionally used in astrology. However, these short descriptions only summarize common astrological associations; they should not be treated as proven statements about a person.

Taurus: the Bull
By comparison, Taurus represents steadiness, comfort, patience, loyalty, and practical persistence.
Gemini: the Twins
Gemini is commonly linked with curiosity, communication, versatility, and quick-moving ideas.
Cancer: the Crab
In traditional astrology, Cancer relates to care, intuition, emotional awareness, home, and protection.
Leo: the Lion
Meanwhile, Leo is associated with warmth, creativity, confidence, generosity, and self-expression.

What information matters?
Do birth time, year, place, or name change your zodiac sign?
Date of birth
Generally, your month and day identify your Western Sun sign. This is what people usually mean when they ask, “What is my zodiac sign?”
Birth time and place
However, birth time and place are essential for a complete natal chart, including the rising sign and houses. They can also settle a Sun-sign question on a transition date.
Birth year
In addition, the year can affect the exact moment of a Western sign change. It also determines your Chinese zodiac animal, subject to the date of Lunar New Year.
Birth name
By contrast, your name does not determine a Western Sun sign. Name-based systems usually belong to numerology or particular naming traditions, not the standard birthday zodiac.
Exact birthday
If your date is comfortably inside a range, the table is enough. Otherwise, use a chart that calculates the Sun’s exact position when the date is near a boundary.
Language
Meanwhile, changing from English to Hindi, Bengali, Punjabi, Marathi, Gujarati, or Telugu changes the sign names or script—not the calculation used by the same astrology system.
Sun sign versus birth chart
A birthday lookup returns one placement: the Sun sign. In contrast, a birth chart uses date, exact time, and birthplace to calculate multiple placements, such as the Sun, Moon, rising sign, planets, and houses. Therefore, a birth chart calculator asks for more information than a simple zodiac-sign finder.
Avoid mixed results
Western, Vedic, and Chinese zodiac signs are different systems
Search results can seem inconsistent when pages calculate different zodiacs. Therefore, first identify which system the page uses.
Western tropical zodiac
First, the Western tropical zodiac uses 12 equal signs tied to the seasonal cycle. A Sun sign is normally found from the birthday month and day, with exact time needed around sign changes.
Vedic or Indian zodiac
By contrast, Jyotish commonly uses a sidereal zodiac and often emphasizes the Moon sign, ascendant, and nakshatra. As a result, a proper calculation normally needs birth date, time, and place.
Chinese or Eastern zodiac
Finally, the Chinese zodiac uses a repeating 12-animal cycle based mainly on birth year. Because Chinese New Year does not begin on January 1, January and February birthdays need the exact year and date.
Why astronomy charts look different: Astrological signs are 12 equal 30-degree sections, while astronomical constellations have unequal boundaries. Moreover, the International Astronomical Union explains that the Sun’s apparent path crosses 13 astronomical constellations, including Ophiuchus. Even so, this does not add a thirteenth sign to the standard 12-sign Western astrology system.
How signs are grouped
Zodiac elements and modalities
Astrology groups the 12 signs by four elements and three modalities. Together, these categories provide a compact way to compare the traditional style assigned to each sign.
Fire signs
Aries, Leo, and Sagittarius make up this group. Traditionally, fire represents action, enthusiasm, expression, and inspiration.
Earth signs
Taurus, Virgo, and Capricorn belong to the earth group. In astrology, earth relates to practicality, stability, resources, and tangible results.
Air signs
Gemini, Libra, and Aquarius form the air group. Similarly, air represents communication, thought, ideas, and social connection.
Water signs
Cancer, Scorpio, and Pisces belong to this element. Traditionally, water relates to emotion, intuition, sensitivity, and inner experience.
Cardinal signs
Aries, Cancer, Libra, and Capricorn are cardinal signs. In other words, astrology describes them as initiators that begin a seasonal phase.
Fixed signs
Taurus, Leo, Scorpio, and Aquarius are fixed signs. As a result, they are traditionally associated with sustaining and consolidating energy.
Mutable signs
Gemini, Virgo, Sagittarius, and Pisces are mutable signs. Finally, astrology links them with adaptation at the close of a seasonal phase.
Quick answers
Frequently asked questions about zodiac signs by birthday
Finding your sign from a birthday
What zodiac sign am I by birthday?
First, match your birth month and day to the 12-sign chart. For most birthdays, no other detail is required. However, if you were born on a transition date such as January 20, March 20–21, April 19–20, or July 22–23, confirm the result with your year, exact time, and birthplace.
Is a zodiac sign based on birthday or name?
A Western Sun sign is based on the Sun’s calculated position at birth. Therefore, the relevant information is your birth date and, near a boundary, time and location. Your name does not determine the sign.
Can two people born in the same month have different zodiac signs?
Yes. In fact, each calendar month contains two signs. For example, someone born on August 10 is a Leo under the common Western ranges, while someone born on August 28 is a Virgo.
What zodiac sign is a birthday today?
Use today’s month and day in the date chart. However, the answer changes around the 19th through 23rd day of each month, depending on the sign boundary.
Does birth time affect my zodiac sign?
Usually not when you are well inside a sign’s range. Nevertheless, birth time matters when the Sun changes signs on your birth date. It is also important for calculating a rising sign, houses, and a complete birth chart.
Does my birth year affect my Western zodiac sign?
Usually the month and day are enough, but the exact transition time varies from year to year. Therefore, birth year can matter on a boundary date. In addition, it matters directly for the Chinese zodiac.
Boundaries, systems, and accuracy
What is a zodiac cusp?
A cusp is the boundary between two signs. People often use “cusp birthday” for dates near that change. However, in a calculated chart, the Sun occupies one sign at a given moment, so exact birth details can resolve the result.
Are zodiac signs astrology or astronomy?
Zodiac signs belong to astrology. By contrast, astronomy scientifically studies space and celestial objects. NASA explains the distinction and notes that astrological claims about personality or prediction are not supported by scientific evidence.
Why do Vedic and Western zodiac signs sometimes differ?
They commonly use different reference systems. Specifically, Western astrology generally uses the tropical zodiac tied to equinoxes and seasons, while Vedic astrology commonly uses a sidereal zodiac adjusted relative to the stars.
Is Ophiuchus a zodiac sign?
Ophiuchus is an astronomical constellation crossed by the Sun’s apparent path. Even so, it is not part of the standard 12-sign tropical zodiac used for common birthday astrology.
Are zodiac personality descriptions scientifically proven?
No. Instead, zodiac traits belong to an astrological and cultural tradition, not a scientifically validated personality test. Therefore, use them for entertainment, reflection, storytelling, or cultural interest rather than important medical, legal, financial, or relationship decisions.
