How we calculate
Hindu panchang & Vedic astrology in your language.
Astronomy
Positions of the Sun, Moon and planets come from the Swiss Ephemeris, a high-precision astronomical ephemeris. Sidereal positions use the Lahiri (Chitrapaksha) ayanamsa, the standard adopted by India's Calendar Reform Committee.
Your city, your time
Every timing is computed for the latitude and longitude of the city you choose and shown in that city's own time zone. Sunrise and sunset are calculated for that place, so a panchang for London or New Jersey is not India's times shifted by a few hours.
Drik timings from sunrise
Tithi, nakshatra, yoga and karana come from the actual (drik) positions of the Sun and Moon, and each day begins at local sunrise, as the traditional Hindu day does. Rahu Kala, Yamaganda and Gulika each take one eighth of the time between sunrise and sunset.
Checked against outside sources
Our calculations are tested against published external references, such as worked examples from classical texts and established tools like Jagannatha Hora, never against our own earlier output.
Both month systems
Amanta (month ends at new moon) and purnimanta (month ends at full moon) are both shown, and each language lists its own tradition's system first.
