Frequently Asked Questions
What if I was born on a cusp date?
If born on the first or last day of a sign, you are on the "cusp." Your actual sign depends on the exact year and time of birth, as dates shift slightly each year.
What are the four elements?
Fire (Aries, Leo, Sagittarius), Earth (Taurus, Virgo, Capricorn), Air (Gemini, Libra, Aquarius), and Water (Cancer, Scorpio, Pisces). Each element shares common traits.
Is astrology scientifically proven?
No. There is no scientific evidence that celestial positions affect personality or predict events. Astrology is considered a belief system, not a science.
What is a rising sign?
Your rising sign (ascendant) is the zodiac sign on the eastern horizon at your exact time of birth. It influences how others perceive you and requires your birth time to calculate.
Why are there 12 zodiac signs?
The 12 signs correspond to 12 constellations along the ecliptic (the sun's apparent path). This system was established by Babylonian astronomers around 500 BCE.
