Free Birth Chart Calculator & Astrology Readings

A birth chart, also called a natal chart or horoscope, is a precise astronomical map of the sky at the exact moment and location you were born. It shows where the Sun, Moon, and all planets were positioned across the 12 zodiac signs and 12 astrological houses. AstroMood generates birth charts using Swiss Ephemeris, the professional-grade astronomical engine that provides planetary positions accurate to 0.001 arc seconds. To create your chart, enter your birth date, exact birth time, and birth city. AstroMood then references its database of 147,000+ cities worldwide to determine your precise coordinates and timezone. The resulting chart includes your Sun sign, Moon sign, Rising sign, Midheaven, all planetary placements, house cusps using the Placidus system, and a complete aspect analysis showing conjunctions, oppositions, trines, squares, and sextiles between your planets.

AstroMood's calculations are among the most accurate available online. The platform uses Swiss Ephemeris, which provides planetary positions accurate to 0.001 arc seconds and covers 13,200 years of ephemeris data spanning from 5400 BC to 7800 AD. Swiss Ephemeris is the same calculation engine trusted by professional astrologers, astronomical research institutions, and planetarium software worldwide. AstroMood combines this precision with a comprehensive location database containing 147,000+ cities sourced from GeoNames, each with verified latitude, longitude, elevation, and historical timezone data. This ensures that house cusps, the Ascendant, and the Midheaven — which change by approximately one degree every four minutes — are calculated correctly even for births in small towns or rural areas. Every chart computed on AstroMood reflects the exact astronomical sky at your moment of birth.

Synastry is the astrological technique of overlaying two natal birth charts to analyze the dynamics of a relationship. AstroMood's compatibility analysis compares the planetary positions of both individuals and identifies cross-aspects — how one person's planets interact with the other's chart positions. For example, when one person's Venus conjuncts the other's Mars, this typically indicates strong romantic and physical attraction. AstroMood analyzes all major aspects including conjunctions, oppositions, trines, squares, and sextiles between both charts. The analysis covers romantic compatibility, emotional connection through Moon aspects, communication style through Mercury contacts, and long-term partnership potential through Saturn aspects. AstroMood supports synastry for any relationship type — romantic partners, friends, family members, or business partners. You can also generate composite charts representing the relationship itself.

Planetary transits are the real-time movements of planets through the zodiac as observed from Earth. When a transiting planet forms a geometric angle (aspect) to a planet in your natal birth chart, it activates and energizes that area of your life for a specific period. AstroMood tracks these transits in real-time against your personal birth chart. For example, Jupiter transiting your 7th house can bring new partnerships and relationship growth, while Saturn transiting your 10th house often restructures your career and public reputation. Outer planet transits by Jupiter, Saturn, Uranus, Neptune, and Pluto create the major life chapters that unfold over months or years. Inner planet transits by the Sun, Moon, Mercury, Venus, and Mars create shorter daily and weekly influences. AstroMood's transit tracker shows which transits are active today with detailed interpretations.
