Is the Janam Kundli generator really free?

Yes — every calculation, every chart style (North, South, East Indian) and the standard PDF are 100% free. No signup, no watermark. A premium plan unlocks AI interpretation, compatibility reports and a designer PDF.

How accurate is the birth chart?

We compute planetary longitudes with the MIT-licensed Astronomy Engine (better than 1 arc-minute), apply the Lahiri ayanamsa for sidereal positions, and use whole-sign houses — the traditional Vedic (Parasari) convention. Validated against 4,700+ reference charts with 99.77% agreement.

Do I need to register or share my email?

No. The kundli, all charts and the standard PDF work without any account. Optional newsletter subscription is separate — we never sell or share your data.

Which chart styles do you support?

North Indian (diamond), South Indian (grid, fixed signs) and East Indian (Bengali) — all three are rendered from the same accurate sidereal chart, so you can switch styles freely.

Which languages does the PDF support?

12 languages: English, Hindi, Marathi, Gujarati, Tamil, Telugu, Kannada, Bengali, Malayalam, Punjabi, Odia and Assamese — with the correct Noto Sans script font embedded for print-quality output.

What information do I need to generate the chart?

Your full name (optional), exact date of birth, exact time of birth, and place of birth (city). The time is the most important input — even a 4-minute error can shift the lagna sign.

Do you use Swiss Ephemeris?

No. We use the fully open-source Astronomy Engine (MIT license) so the entire calculation stack is transparent, redistributable and free of paid API dependencies.

Can I download or print the kundli?

Yes — one-click download as a premium multi-page A4 PDF (cover, three chart styles, planet & house tables, nakshatra panel, summary, QR code) or print directly from your browser.
