Dasha Compatibility (Deep Compatibility)
The fourth Deep Compatibility section (max 10 points) — unlike the other 3 sections which look at fixed birth-chart factors, this one looks at TIMING: which Dasha period each partner is currently running, and whether the currently-active planetary periods are themselves supportive of marriage.
Venus, Jupiter, Moon, and Mercury Mahadashas are treated as marriage-supportive; the Sun's is neutral; Mars, Saturn, Rahu, and Ketu are treated as more challenging for this specific purpose — this section also flags if a partner is close to transitioning out of their current Dasha, since that shift itself can matter for timing.
Scores each partner's current Mahadasha lord against the marriage-supportive/neutral/challenging classification above, factors in the Antardasha quality and whether the two partners' current Dasha lords are themselves friendly with each other, and shows both partners' exact current Mahadasha-Antardasha combination for reference.
