The stars have been looked at for information since the Babylon period. 12 constellations in the sky, representing the 12 months gave rise to 12 zodiac signs. These signs are also associated with the different planets. Each sign occupies a sector of the sky which makes up 30° of the ecliptic.
Astrology has 2 branches- Western astrology and Vedic astrology. While Western Astrology uses the Tropical Zodiac to determine your particular zodiac sign, Vedic Astrology uses Sidereal Zodiac. Hence, when consulting an astrologer, you should know which system they follow.

The time of your birth, hence, plays a vital role in getting a more accurate birth chart. You could find your zodiac sign online on the various sites available, but they may lack accuracy and may not provide a detailed and personalized analysis.
