Electional astrology
Electional astrology, also known as event astrology, is a branch found in most traditions of astrology according to which a practitioner decides the most appropriate time for an event based on the astrological auspiciousness of that time. It differs from horary astrology because, while horary astrologers seek to find the answer to a question based on the time the question was asked, electional astrologers seek to find a period of time which will result in the most preferable outcome for an event being planned.
