Panchangam is the official astrological calendar of practicing Hindus. It forecasts celestial phenomena such as solar eclipses as well as more mundane occurrences. The study of Panchangam involves understanding Rasi phala, the impact of the signs of the zodiac on the individual. Astrologers consult the Panchangam to set dates for weddings, corporate mergers, and other worldly activities. Also see Hindu Calendar.
