ModernAstro is a professional-grade Vedic astrology platform built on an observatory-grade astronomical engine trusted by research institutions worldwide. We offer 100+ calculation endpoints covering birth charts, Dashas, Nakshatras, Yogas, Doshas, numerology, Panchang, and more.

Our calculations are powered by a professional-grade astronomical engine, the gold standard in ephemeris computation. Planetary positions are accurate to the arc-minute level (approximately 0.017 degrees). This is the same precision used by professional observatories and astronomical research institutions worldwide. All results are cross-verified against established reference sources.

You need three pieces of information: your date of birth, your exact time of birth, and your place of birth. The time of birth is especially critical — even a difference of a few minutes can shift house cusps and alter Dasha period boundaries. If you do not know your exact birth time, check your birth certificate or hospital records. We recommend accuracy to at least the nearest minute.

A Kundli (also called Janam Kundali or Vedic birth chart) is a diagram showing the exact positions of the Sun, Moon, planets, and other celestial points at the precise moment and location of your birth. It forms the foundation of Vedic astrology — from your Kundli, astrologers derive your Rasi (Moon sign), Lagna (Ascendant), Nakshatra, planetary Dashas, Yogas, and much more.

Sade Sati is a significant 7.5-year period in Vedic astrology that occurs when Saturn (Shani) transits through the 12th, 1st, and 2nd houses relative to your natal Moon sign. Since Saturn takes approximately 29.5 years to orbit the Sun, Sade Sati occurs roughly two to three times in a person's lifetime. It is traditionally associated with challenges and transformation, though the actual effects vary depending on Saturn's placement and aspects in your birth chart.

The primary difference is the zodiac system. Vedic astrology (Jyotish) uses the sidereal zodiac, which is aligned with the actual positions of the constellations in the sky. Western astrology uses the tropical zodiac, which is fixed to the seasons (equinoxes and solstices). Due to the precession of the equinoxes, these two systems currently differ by about 24 degrees. Vedic astrology also includes unique systems not found in Western practice, such as Nakshatras (27 lunar mansions), Dasha timing systems, and Divisional charts (D1 through D60).
