Zodiac Sign Calculator

1. Pick your date of birth with the date picker.
2. Read your zodiac sun sign.
3. See its element, one of fire, earth, air or water.
4. Check the date range the sign covers.

Here is what each result means:

A zodiac sign, or sun sign, is the part of the sky the Sun appeared to be in when you were born, as seen from Earth. Western astrology divides the year into twelve signs, each covering about a month, from Aries in spring through to Pisces. Your sign is set purely by the month and day of your birth, not the year.

The twelve signs are grouped into four classical elements, fire, earth, air and water, with three signs in each. Fire signs are Aries, Leo and Sagittarius; earth signs are Taurus, Virgo and Capricorn; air signs are Gemini, Libra and Aquarius; and water signs are Cancer, Scorpio and Pisces. These groupings are a big part of how astrology describes personality.

It is worth being clear that astrology is a cultural and entertainment tradition, not a science. The sign boundaries also shift by about a day from year to year, so a birthday that falls right on the edge, or cusp, between two signs can be reported differently by different sources. This calculator uses the widely quoted standard ranges.

It matches your birth month and day against the twelve sign ranges.

1. Your birth date is read as a month and a day; the year does not matter.
2. The month and day are compared with the start date of each sign.
3. The sign whose range contains your date is returned, with its element.

For other birth-date tools, see the Chinese zodiac calculator and the age calculator.

Take a birth date of 5 August.

Result: that falls between 23 July and 22 August, so the sun sign is Leo, a fire sign. A date of 14 February is Aquarius, an air sign, while 25 December is Capricorn, an earth sign.

Each sign covers roughly a month of the year.

These are the widely used tropical dates. Because the calendar and the sky do not line up perfectly, the exact changeover can move by a day in some years.

Astrology groups the signs into four elements, each said to share a temperament.

These themes are part of astrological tradition, not scientific fact. They are, however, the main way the twelve signs are described and compared, so knowing your element is a common starting point.

Your Month and Day

The sun sign depends only on the month and day of birth, so the year makes no difference.

Cusp Dates

Births right on the boundary between two signs can vary by a day depending on the year and source.

Tropical vs Sidereal

Western astrology uses the tropical zodiac; the sidereal zodiac used elsewhere shifts the dates by weeks.

Fun and Curiosity

Explore signs and elements for entertainment.

1. Using the Birth Year

The sun sign depends only on the month and day. The year does not change it.

2. Assuming Fixed Cusp Dates

The changeover between signs can move by a day between years, so cusp dates are not exact.

3. Confusing Tropical and Sidereal

The sidereal zodiac used in some traditions gives different dates from the Western tropical one.

4. Mixing Up Sun and Moon Signs

This is the sun sign. Moon and rising signs need a birth time and place.

5. Treating It as Science

Astrology is for interest and fun, not evidence-based guidance.

The sign follows the standard tropical date ranges, which can shift by a day near a cusp.

Enter your birth date and the calculator returns your sun sign. Only the month and day matter, not the year. A 5 August birthday is a Leo.

Each sign covers about a month, such as Leo from 23 July to 22 August and Aquarius from 20 January to 18 February. The full list is in the table above.

No. The sun sign depends only on the month and day of birth. People born on the same day in different years share the same sign.

A cusp is a birthday right on the boundary between two signs. Because the changeover can shift by a day between years, cusp dates are sometimes reported differently.

The twelve signs are grouped into four elements: fire, earth, air and water, with three signs each. Your element is a common way to describe your sign.

The sun sign comes from your birth date. Moon and rising signs also need your exact birth time and place, which this calculator does not use.

Cusp dates vary slightly by year and source, and the sidereal zodiac used in some traditions gives different ranges from the Western tropical one used here.
