To compute the opening Mahadasha balance at birth, the astronomer subtracts the Moon's elapsed minutes inside the occupied Nakshatra from 800 arc-minutes, divides the remaining arc by 800, and multiplies by the full period of that Nakshatra's lord. Every Mahadasha subdivides recursively in the exact same 120-part ratio across five tiers: Mahadasha, Antardasha (Bhukti), Pratyantardasha, Sookshma Dasha, and Prana Dasha.
