How is a Vedic chart different from a Western chart?
Vedic (sidereal) astrology measures planets against the fixed stars, so your signs are usually shifted about 24° (roughly one sign back) from your Western (tropical) placements. It also emphasizes the moon sign and dasha timing.
What is a nakshatra and a dasha?
Your nakshatra is the lunar mansion (1 of 27) your Moon occupied at birth — a core signature in Vedic astrology. The Vimshottari dasha is a 120-year planetary timeline that shows which planet rules each chapter of your life.
Do I need my exact birth time?
For the moon sign and nakshatra a birth date usually suffices, but your lagna (rising sign) and dasha timing need an accurate birth time.
