Raman Porphyrius Birth Chart Calculator

This calculator uses Raman sidereal zodiac system and Porphyrius house system.

The Raman ayanamsa, developed by B.V. Raman, is one of the most respected sidereal systems in Indian astrology. It is similar to the Lahiri system but with slight differences in calculation, making it a popular choice among traditional Vedic astrologers.

The Porphyrius house system, named after the 3rd-century philosopher Porphyry, is a quadrant system that divides the space between the angles (Ascendant, IC, Descendant, MC) into three equal parts. It is one of the oldest house systems still in use today.
