What is Balance of Dasha?
At birth, the Moon occupies a specific Nakshatra, and the Dasha lord of that Nakshatra is the first Mahadasha lord. However, since birth rarely coincides with the Nakshatra's start, only a fraction of that first Mahadasha remains. This fraction is the Balance of Dasha, calculated from the Moon's exact position within the Nakshatra. For example, if the Moon is at 60% of Rohini (Venus-ruled), only 40% of Venus Mahadasha remains — about 8 years of the 20-year Venus period. This balance determines the exact starting point for all subsequent Dasha periods.
