Vimshottari Mahadasha
Vimshottari Mahadasha is the most commonly used planetary timing system in Vedic astrology.
Overview
Vimshottari Mahadasha is a 120-year planetary timing system connected to the Moon nakshatra at birth. This is one reason the natal Moon is so important in jyotish: it helps determine the dasha sequence you are born into.
How To Use This
The mahadasha shows the larger chapter, while sub-periods and transits refine the timing. In practice, it helps explain why certain chart themes become louder at certain times in life.
