Numbers you were born with, and the ones you choose

Your full name as you currently use it, your date of birth, and for some reports the time and place of birth. For kundli matching we need the exact time and place of birth for both partners.

The calculators use the standard Chaldean, Pythagorean and Indian (Mulank–Bhagyank) methods, and kundli matching uses a computed Moon position with Lahiri ayanamsa. They are a good first look; a personal report adds the judgement that formulas cannot.
