✦FREE NATAL CHART · YOUR PERSONAL COSMIC BLUEPRINT
Calculate your Sun, Moon, and Rising signs, then explore all ten planetary placements, twelve houses, and the aspects that connect them.
A GUIDE TO YOUR NATAL CHART
Your birth chart brings several layers of astrological symbolism into one picture. Start with your Sun, Moon, and Rising signs, then explore how the other planets, houses, and aspects connect. You do not need to memorize every placement at once; choose one question about your everyday experience and use the chart as a starting point for reflection.
The Sun symbolizes identity and creative direction. The Moon describes emotional needs and familiar responses. The Rising sign, also called the Ascendant, frames how you approach new experiences. A Sun-sign horoscope addresses just one part of this picture; a natal chart adds the Moon and the birth-location-dependent horizon.
Read the Sun, Moon & Rising guide →In a chart reading, a planet suggests a theme, its sign describes a style, and its house identifies an area of life. Mercury in a sign describes a communication style; Mercury in a house adds a context, such as learning, relationships, or public life. Whole sign houses follow the Ascendant’s sign, so a reliable birth time matters.
Explore the twelve zodiac signs →Aspects measure angular separations between planets. Conjunctions bring themes together, oppositions invite balance, and squares suggest tension to work with. Trines and sextiles are traditionally associated with ease and cooperation. The orb measures how far an aspect is from its exact angle; the result lists tighter aspects first.

We calculate geocentric ecliptic longitudes with Astronomy Engine, including light-travel correction and the true equinox and ecliptic of date. The twelve tropical signs are equal 30° sectors. Birthplace coordinates define the local horizon; the IANA time zone converts your local birth time to the UTC calculation instant.
The Ascendant is the eastern intersection of the ecliptic and horizon. Whole sign houses begin at 0° of the Ascendant’s sign. The MC is the upper intersection with the meridian and is reported separately. We omit angles and houses for unknown birth times and for polar latitudes of 66.5° or beyond. Displayed degrees are truncated to arcminutes; they are not a claim of birth-record precision.
Astronomical positions can be calculated and compared. Their astrological interpretations are cultural and symbolic, and are not scientifically established predictions of personality or future events. Use this free natal chart calculator for exploration, journaling, and a more thoughtful reading of astrological language.

A LITTLE MORE CLARITY
A birth chart is a map of the Sun, Moon, and planets as seen from Earth at your birth instant. Astrologers divide the zodiac into twelve signs and connect placements with houses and aspects. This calculator uses the tropical zodiac and whole sign houses. The planetary positions are astronomical calculations; their personal meanings are symbolic interpretations.
Enter your birth date, the local time on your birth record, and your birth city. Select the correct city to supply latitude, longitude, and a suggested IANA time zone. The calculator converts the local time to UTC, calculates planetary longitudes, and finds the eastern intersection of the zodiac with your horizon to determine the Ascendant.
Yes. Select ‘I don’t know my birth time’ to receive a local-noon reference chart. The result shows possible planetary signs across the full local day. The Moon, and occasionally another body, may change signs that day. Rising sign, Midheaven, and house placements are omitted because they cannot be reliably determined without a birth time.
Zenith uses geocentric tropical zodiac positions and whole sign houses. The full sign containing the Ascendant is house one, beginning at 0 degrees of that sign; each following sign forms the next house. The Midheaven is calculated separately. This is not a sidereal, Vedic, or Placidus calculator, so results can differ from tools using those systems.
The selected IANA time zone determines the historical UTC offset for your birth date. If a local time occurred twice during a clock change, the calculator asks you to select the first or second occurrence. A time that never occurred is rejected. Geographic time-zone suggestions and especially pre-1970 records should be verified against your birth record.
The result includes the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto; their signs, degrees, and apparent motion; major aspects and their orbs; and symbolic interpretations. With a known birth time and a supported latitude, it also includes Rising sign, Midheaven, and all twelve whole sign houses. You can download the calculated chart data without an account.
Check the birth time, city coordinates, UTC offset, tropical versus sidereal zodiac, and house system first. Geocentric versus topocentric positions and different ephemerides or aspect orbs can also produce small differences. This calculator shows its calculation instant and settings so you can compare like with like. Angles and houses are omitted at latitudes of 66.5 degrees and beyond.
This calculator sends your birth details to the calculation endpoint and holds the result in page memory. It does not create an account or save the birth details in a database or browser storage. City searches send the city name to the geocoding provider. Chart data is saved to your device only when you choose to download it.
