Jotiz Compatibility algorithms use just the birth-dates. We understood how cumbersome (if not impossible) it is to obtain accurate birth time and place as used in traditional matches. The computed charts in Jotiz Congruence disregard ascendant, MC and descendant which are fast moving and may require accurate times and place. Outer planets impose an impressive influence on natives, so do some of the slower moving planets. Composite charts and inter-chart aspects and planetary comparisons are used in Jotiz Congruence.
