Your date of birth comes with two popular bits of trivia: your zodiac (star) sign, set by where the Sun was when you were born, and your birthstone, traditionally tied to your birth month. Here’s a quick reference for both.
Zodiac signs by date
The Western zodiac splits the year into 12 signs. The dates can vary by a day from year to year because the Sun’s position shifts slightly, so if you were born right on a cusp, your sign may differ by a day depending on the year and time.
| Sign | Dates |
|---|---|
| Capricorn | Dec 22 – Jan 19 |
| Aquarius | Jan 20 – Feb 18 |
| Pisces | Feb 19 – Mar 20 |
| Aries | Mar 21 – Apr 19 |
| Taurus | Apr 20 – May 20 |
| Gemini | May 21 – Jun 20 |
| Cancer | Jun 21 – Jul 22 |
| Leo | Jul 23 – Aug 22 |
| Virgo | Aug 23 – Sep 22 |
| Libra | Sep 23 – Oct 22 |
| Scorpio | Oct 23 – Nov 21 |
| Sagittarius | Nov 22 – Dec 21 |
Birthstones by month
Birthstones are linked to your birth month rather than a date range, which makes them simpler. The modern list most widely used is:
| Month | Birthstone | Month | Birthstone |
|---|---|---|---|
| January | Garnet | July | Ruby |
| February | Amethyst | August | Peridot |
| March | Aquamarine | September | Sapphire |
| April | Diamond | October | Opal / Tourmaline |
| May | Emerald | November | Topaz / Citrine |
| June | Pearl / Alexandrite | December | Turquoise / Tanzanite |
A note on these traditions
Zodiac signs and birthstones are cultural traditions and folklore rather than science — a fun part of a birthday, not a forecast. Birthstone lists in particular vary between countries and jewellers, so you’ll sometimes see different stones for the same month.
Find yours, then check your age
Locate your birth date in the zodiac table and your birth month in the birthstone table to find both. While you’re here, the age calculator will tell you exactly how old you are today, and the birthday countdown shows how long until your next birthday rolls around.
