Jyotish reference

Free Jyotish calculators

Quick calculations from your date, time and place of birth: your whole Vedic chart explained in plain words, Manglik dosha with its cancellation rules, your Moon nakshatra and current dasha, every Sade Sati period with dates, and a couple's 36-guna compatibility.

How the calculators work

All of them use the same calculation as the charts in the JyotiSoft bot and Mini App: sidereal zodiac, Lahiri ayanamsha, true lunar node. The birthplace is found by a geocoder with the historical time zone for the birth date — important for dates when time zones changed often.

What happens to my data

To keep your chart and get personal guidance, open the Mini App, where the data lives in your profile.

Day rhythm by city

Panchang city pages: Rahu Kalam, Abhijit, choghadiya, hora, tithi, nakshatra, yoga and karana from sunrise to the next sunrise, in your city's time, with a “now” line.

What next

A calculator shows one layer of the chart. A full Vedic reading — character, work, relationships, the periods of the coming years — is the PDF reading; daily guidance from your chart comes from the bot and the Mini App.

Questions

How accurate are the calculators?
Planetary positions are accurate to fractions of an arcminute. The main source of error is the birth time, which decides the lagna and sometimes the Moon's nakshatra.
Why is my nakshatra different on other sites?
Usually because of the time zone on the birth date or a different ayanamsha. We use the historical time zone and the Lahiri ayanamsha.
Is this a North or a South Indian chart?
South Indian: the signs keep fixed boxes and the lagna is marked. A North Indian chart fixes the houses instead; the data is the same in a different frame.
Can I calculate without a birth time?
Yes. Without a time the calculator uses noon and warns you if the Moon changed nakshatra that day.
