I will build an accurate astrology or astronomy calculator for your website
Chandan K
About this gig
Need an astrology or astronomy calculator you can trust? I build calculation engines that are tested, not guessed.
My own Vedic engine is checked against independent references:
- Moon within 0.008 arc-seconds of Swiss Ephemeris (2,000 moments)
- Planets within 0.05 arc-seconds of NASA JPL Horizons (after the known ecliptic-frame offset)
- Eclipse type identical to NASA's canon for all 909 eclipses, 1901 to 2100
- Sunrise matching the US Naval Observatory to the minute
What I can build for you:
- Kundli or birth-chart calculator: planets, ascendant, houses, nakshatra, dasha
- Panchang, muhurat, rahu kaal, choghadiya or hora for any city and time zone
- Kundli matching (ashtakoota) or numerology
- Sunrise, moonrise, eclipse or planet-position widgets
Every engine ships with automated tests, so you can see it is right. It runs in the browser (birth details stay on the user's device) or as a Node.js API, with an English or Hindi interface. Clean, commented JavaScript that you own.
Message me before ordering with what you need; I reply with a clear scope and price.

I build systems that do the work for you. As an AI automation developer, I built a 19-tool automation platform for US small businesses: missed-call text-back, AI receptionists, lead follow-up, reminders and review requests, using n8n, Zapier, Make, Twilio and AI. As Astro Engineers, my kundli engine matches NASA JPL planet positions to within 0.05 arc-seconds, and I deliver Vedic birth chart reports, Vastu analysis and custom astrology calculators. Clear scope, honest delivery, revisions included.

FAQ
Which calculation methods do you support?
Lahiri ayanamsa by default, plus KP, Raman and Fagan-Bradley; Placidus or Sripati houses; Vimshottari dasha. Tell me the tradition your users follow and I match it.
Can it run without a server?
Yes. The engine runs in the browser, so birth details never leave the user's device. A Node.js API version is available for apps and backends.
How do I know the results are correct?
Every delivery includes automated tests that compare the results with independent references such as Swiss Ephemeris and NASA JPL Horizons. You can run them yourself.
Will it work on my website?
Yes. I deliver a small JavaScript module plus a ready widget you can place on any page, including WordPress, React or plain HTML. Tell me your setup and I match it.
