About JyotishKosh

JyotishKosh offers free Hindi tools for kundli, kundli matching and panchang. They run on astronomical calculation and show the results in plain Hindi.

What you will find here

• Janm kundli: lagna, planetary positions, nakshatra and Vimshottari dasha.
• Kundli milan: the 36 gunas of ashtakoot matching, with the points for each koot.
• Manglik check: the position of Mars, counted from the lagna and from the Moon.
• Today's panchang: tithi, nakshatra, rahukaal and sunrise for your city.

At present the site gives calculations and plain information about them. Each tool states which rule or tradition it follows. The tools themselves are in Hindi.

How the calculations are made

• Positions of the Sun, Moon and planets come from Astronomy Engine, an open-source astronomy library.
• The ayanamsa is Lahiri (Chitrapaksha). Rahu and Ketu use the mean node, and houses are whole-sign, as in a North Indian chart.
• A panchang day runs from sunrise to the next sunrise, and all times are worked out for the chosen city.
• Our results were compared with Swiss Ephemeris, which is widely used in astrology software. Across 50 birth moments the largest difference in a planet's position was 11 arcseconds, less than a fifth of an arcminute. The largest difference in the end time of a tithi or nakshatra was about 11 seconds.
• Traditions differ on some points, such as a few of the kundli-matching tables and the way lunar months are counted. Where they do, we use the common method and say so on the page.

What we do not do

• We do not keep your birth details. All calculation happens in the browser on your own phone or computer. See the privacy policy.
• We do not guarantee any outcome. See the disclaimer.
