Frequently asked questions
Are these calculators really free?
Yes. Every calculator on this page is free to use, with no sign up and no payment. You can run as many charts as you like, subject to a fair use limit of 30 calculations per hour from one connection.
How accurate are the results?
The math is the same Swiss Ephemeris astronomical engine, sidereal zodiac with Lahiri ayanamsa, and whole sign houses used across the rest of Purohit. The one variable you control is birth time: an approximate time is fine for Moon based calculators (nakshatra, moon sign, sade sati, kaal sarp) but Lagna and Dasha need the real clock time to be reliable.
What if I do not know my exact birth time?
Leave the time field blank for Manglik, Kaal Sarp, Sade Sati, Nakshatra or Moon Sign: the calculator falls back to a 12 noon placeholder and tells you it did so. Lagna and Dasha genuinely need a real time, since both change with the clock, so those two ask you to provide one.
Do I need to create an account?
No. These calculators run without any login. If you want a saved, shareable chart with the full planet table, panchang and dasha timeline together, the free kundli tool builds that from the same birth details in under a minute.
Can I ask a real astrologer about my result?
Yes. Every calculator result links to a WhatsApp chat with Purohit, an AI purohit trained on the classical corpus, where you can ask what a Manglik or Kaal Sarp verdict actually means for your own chart in plain language.
