Your zodiac sign comes from your birth date. There are twelve signs, each covering about a month, so look up the date you were born: 15 August is Leo and 5 January is Capricorn. Use the free Zodiac Sign Calculator to get your sign, element and traits from your birthday in seconds.
The 12 Zodiac Signs and Their Dates
The twelve signs run through the year in the same order. These are the standard dates used by most newspapers and horoscope sites, and they match the calculator on this site.
| Sign | Dates | Element |
|---|---|---|
| Aries | 21 March – 19 April | Fire |
| Taurus | 20 April – 20 May | Earth |
| Gemini | 21 May – 20 June | Air |
| Cancer | 21 June – 22 July | Water |
| Leo | 23 July – 22 August | Fire |
| Virgo | 23 August – 22 September | Earth |
| Libra | 23 September – 22 October | Air |
| Scorpio | 23 October – 21 November | Water |
| Sagittarius | 22 November – 21 December | Fire |
| Capricorn | 22 December – 19 January | Earth |
| Aquarius | 20 January – 18 February | Air |
| Pisces | 19 February – 20 March | Water |
Each sign is traditionally linked to a set of traits. Aries is described as fearless and dynamic, Taurus as steady and loyal, Gemini as inquisitive and communicative, Cancer as devoted and sensitive, Leo as radiant and big-hearted, Virgo as grounded and detail-focused, Libra as tactful and fair, Scorpio as intense and courageous, Sagittarius as upbeat and sincere, Capricorn as steadfast and dependable, Aquarius as free-spirited and inventive, and Pisces as empathetic and creative.
Born on a Cusp Date?
If your birthday falls on the first or last day of a sign, you are on what astrologers call a cusp. The exact changeover day can shift by a day from year to year, because the Sun does not enter each sign at the same hour every year. Someone born on 20 March might be Pisces in one year and Aries in another, depending on the year and the time of day.
If you were born on a boundary date, the date alone is not quite enough — you would need your birth year and time to be sure. The calculator uses the standard date ranges above, which are right for the large majority of birthdays. For cusp birthdays, treat the result as the most likely sign and check the exact changeover for your birth year if it matters to you.
The Four Elements
The twelve signs are grouped into four elements, three signs each. Fire signs — Aries, Leo and Sagittarius — are described as energetic and bold. Earth signs — Taurus, Virgo and Capricorn — are described as practical and steady. Air signs — Gemini, Libra and Aquarius — are described as curious and social. Water signs — Cancer, Scorpio and Pisces — are described as sensitive and intuitive.
The elements are the reason some signs are said to get along well: signs of the same element are often described as natural matches, while fire and air are said to feed each other, and earth and water are said to balance each other. This is part of the fun of astrology, not a rule about real relationships.
What Your Sign Is Used For
Most people meet their zodiac sign through horoscopes — the short daily, weekly or monthly forecasts in newspapers, apps and magazines. Your sign is also used for birthday gifts, compatibility charts, tattoos and party themes. For many people it is simply a piece of identity, like a birthstone or a favourite colour.
It is worth being honest about what a zodiac sign is. There is no scientific evidence that the position of the Sun on your birthday shapes your personality or your future. Studies that have tested it properly have found no link. That does not make star signs useless — as entertainment, as a conversation starter and as a prompt for self-reflection, they are harmless fun. It only becomes a problem when someone sells certainty they cannot deliver, or when a forecast replaces real advice about health, money or relationships.
If you enjoy horoscopes, read them the way you would read a fortune cookie: for fun, not for decisions. A good horoscope can still be useful as a nudge to reflect — to call a friend, to start a project, to take a break — as long as you remember that you are the one making the choice, not the stars.

Frequently Asked Questions
How do I know my zodiac sign by birth date?
Look up your birthday in the twelve-sign table: each sign covers about a month, so your birth date falls inside one sign. For example, 15 August is Leo and 5 January is Capricorn. If you were born on a boundary date, use a calculator, because the changeover day can shift by a day from year to year.
What is my zodiac sign if I was born on a cusp?
A cusp birthday falls on the first or last day of a sign, and the sign can depend on your birth year and time of day. The standard date ranges give the most likely sign, but for a certain answer you would need the exact moment the Sun changed signs in your birth year.
Are zodiac signs real?
Zodiac signs are real as a cultural tradition that is thousands of years old, but there is no scientific evidence that they shape personality or predict the future. Treat them as entertainment and a fun way to reflect on yourself, not as a forecast or a substitute for real advice.
What is the difference between a zodiac sign and a birth chart?
Your zodiac sign, also called your sun sign, comes from your birth date alone and is one piece of astrology. A birth chart is a bigger map that adds the moon phase, the other planets and the houses, and a full chart also needs your exact birth time and birth place.
