12 Whole-Sign Houses
9 Chart Bodies
3 Chart Layouts

Engineered for Accuracy & Depth

IrAstra bridges NASA-derived astronomical ephemerides with centuries-old traditional astrology methods.

01
JPL Ephemeris 2.1.19

Ephemeris Precision

Calculates geocentric ecliptic longitudes powered by Astronomy Engine 2.1.19, providing exact celestial position telemetry.

02
Tropical ⚡ Sidereal

Dual Tradition Engine

Seamlessly toggle between Western Tropical zodiac wheels and Indian Sidereal (Lahiri Nirayana) diamond/square Kundali layouts.

03
12 Equal Houses

Whole-Sign House System

Employs traditional whole-sign house division, allocating 30° per sign for clear, uncluttered house placement analysis.

04
27 Lunar Mansions

Nakshatra & Dasha Telemetry

Computes 27 Lunar Mansions (Janma Nakshatra), exact Padas, and Vimshottari Dasha planetary lords for Vedic analysis.

Western Wheel & Indian Kundali

Enter an accurate local birth time, coordinates, and UTC offset. Planetary longitudes use Astronomy Engine; charts use whole-sign houses and an approximate Lahiri sidereal offset.

Demo locations:

Birth Parameters

Use the offset that applied at the birth place and date, including daylight-saving time.

Transparent use: astronomical longitudes are ephemeris-backed. House layout and sidereal conversion follow stated astrology conventions. Astrology interpretations are cultural and reflective, not scientific predictions or professional advice.

Methodology & Transparency

Clear answers about our astronomical calculations, astrology conventions, and privacy commitment.

Western charts use the Tropical zodiac aligned with seasonal equinoxes. Indian (Vedic) Kundali charts use the Sidereal (Nirayana) zodiac, which factors in precession (ayanamsha) to align with physical constellations. IrAstra lets you calculate and compare both seamlessly using Astronomy Engine longitudes.

We use an approximate Lahiri ayanamsha algorithm based on standard astronomical precession rates (~23.8° for contemporary dates), ensuring reliable conversion from tropical to sidereal longitudes.

All planetary positions are computed via Astronomy Engine 2.1.19, an open-source high-precision astronomical library based on JPL ephemerides. Calculations are precise to fractions of an arcminute.
