A horoscope is a summary of the sky. Here we show you the coordinates before the summary. We calculate the ecliptic longitude of 10 celestial bodies to the arcminute using NASA JPL ephemeris, and trace back your birth timezone to erect the Ascendant and houses.

Enter your birth date, time, and location to generate a natal chart calculated using real astronomical ephemeris data (NASA JPL based). The chart plots all 10 planets across the 12 zodiac signs and houses, using your choice of Placidus or Whole Sign house systems. Your Big Three (Sun, Moon, Rising) are highlighted for quick reference.
The tool includes aspect detection (conjunctions, trines, squares, oppositions, sextiles), pattern recognition for Grand Trines and Stelliums, over 240 interpretations for planet-sign placements, a 3D celestial chart visualization, daily horoscope for all 12 signs, and sign compatibility analysis. The more accurate your birth time and location, the more reliable your Moon sign, Ascendant, and house placements.

Positions are calculated using the astronomy-engine library based on NASA JPL data, matching Swiss Ephemeris tools within 1 arcminute. This is the same data source used by professional astrology software.
The Big Three are your Sun sign (core identity), Moon sign (emotional nature), and Rising sign / Ascendant (outward personality and first impression). Together they form the foundation of your astrological profile.
Two house systems are supported: Placidus (the most widely used system, based on time-based divisions) and Whole Sign (where each house corresponds exactly to one zodiac sign).
An accurate birth time is important for calculating your Ascendant (Rising sign), Moon sign, and house placements. Without it, Sun sign and most planetary positions remain accurate, but houses and the Ascendant may be off.
