About Udayatara

Udayatara means "the rising star". Udaya is the rising of the sun at dawn, and tara is a star. We chose the name because a good reading should help you rise above your limits, one clear day at a time. It is a Vedic astrology (Jyotisha) site and app that reads your birth chart the classical way and explains it in plain words. You don't need to know Sanskrit or astrology to use it. Each term is explained the first time it appears.

How we calculate

  • Sidereal zodiac with the Lahiri (Chitrapaksha) ayanamsa, the standard used in India. That's why your Sun sign here can differ from a Western horoscope.
  • Planet positions from a precise astronomical model. Rahu and Ketu use the mean node, so they always move backward.
  • Interpretation follows Parashara's system, from the Brihat Parashara Hora Shastra: the rashi chart (D1), the navamsha (D9), the 27 nakshatras and their padas, and the Vimshottari dasha periods.
  • Panchanga (the daily almanac: tithi, nakshatra, yoga, karana) is worked out for your own place, from true local sunrise.
  • Matchmaking uses the classical Ashtakoota (eight-part) score out of 36.
  • Birth places come from a world list of over 150,000 towns, with the correct time zone for the date you were born.

One tip: your birth time matters. A difference of a few minutes can change the rising sign (lagna). For births in Mumbai before about 1955, or Kolkata before about 1948, clocks may have kept local city time, so check the time on the birth record.
