Frequently Asked Questions
Why is Moon sign more important in Vedic astrology?
The Moon represents mind (Manas), emotions, and daily mental state. Since we experience life through our mind, the Moon sign provides more relevant daily guidance. The Dasha system and most predictions are Moon-based.
Why does Western astrology use Sun sign?
Western astrology emphasizes the ego, conscious identity, and life purpose - all Sun domains. This approach reflects Western culture's focus on individual expression and self-actualization.
Can my Moon sign and Sun sign be the same?
Yes, this happens when someone is born during a New Moon phase, when Sun and Moon are in the same sign. This creates a focused personality but may lack internal balance.
Which sign should I read horoscopes for?
For Vedic horoscopes (Rashifal), use your Moon sign. For Western horoscopes, use your Sun sign. Both can offer insights, but Moon sign predictions typically resonate more with daily experiences.
How do I find my Moon sign?
Your Moon sign requires knowing your exact birth time and location. The Moon moves through one sign every 2.25 days, so precision matters. Use our Rashi Calculator for accurate results.
