It's important to note that:
* The modern astronomical definition of the zodiac is different from the astrological one. Astronomically, the zodiac is based on the Earth's orbit around the sun, with the sun passing through 13 constellations over the course of a year.
* Astrology is not a science and has no scientific basis. While it's fun to read your horoscope, it doesn't have any real influence on your personality or destiny.
The 12 traditional zodiac signs are:
1. Aries (March 21 - April 19)
2. Taurus (April 20 - May 20)
3. Gemini (May 21 - June 20)
4. Cancer (June 21 - July 22)
5. Leo (July 23 - August 22)
6. Virgo (August 23 - September 22)
7. Libra (September 23 - October 22)
8. Scorpio (October 23 - November 21)
9. Sagittarius (November 22 - December 21)
10. Capricorn (December 22 - January 19)
11. Aquarius (January 20 - February 18)
12. Pisces (February 19 - March 20)
The 13th constellation that is included in the astronomical zodiac is Ophiuchus. However, Ophiuchus is not used in traditional astrology.
