About Free Horoscope Natal Chart

What The Site Is And Why It Is Free

Free Horoscope Natal Chart is a free natal chart calculator that anyone can use without an account or sign-up. You enter an optional first name, a birth date, a birth time and a birthplace, and the chart appears immediately.

The site is independently run. There is no advertising, no analytics cookies and no third-party trackers, so the calculator is free in the fullest sense: nothing about your visit is sold or profiled. Everything runs on Cloudflare at a cost low enough that we do not need to charge for a chart.

The chart lists the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, the true North Node, mean Black Moon Lilith, the Ascendant, Midheaven, Descendant, IC and Part of Fortune, with aspects and house placements. A paid personal reading is planned later, but the chart itself stays free.

How The Chart Is Calculated And Tested

Every chart is calculated inside your own browser, not on a server. Planet positions come from Astronomy Engine, an open-source MIT-licensed library that corrects for light-time, aberration, precession, nutation and Delta T. Ascendant, Midheaven, house cusps, lunar nodes and Lilith are computed by our own code.

The zodiac is tropical, measured from the March equinox, using the true ecliptic and equinox of date. Houses are Placidus by default, with Whole Sign and Equal houses available. Above the polar circles Placidus cannot be drawn, so the chart falls back to Porphyry houses there.

In November 2026 we ran an accuracy test: 300 random charts from 1900 to 2030 recalculated with Swiss Ephemeris 2.10, the reference software most professional astrology programs use. Planets agreed within 19 arcseconds (the Sun within 3, the Moon within 5), and every Placidus house cusp, the Ascendant and the Midheaven within half an arcsecond. The true North Node matched within 15 arcseconds. Mean Lilith differed by up to about 7 arcminutes because programs define that point slightly differently, which is why we show it to the whole degree. One degree is 3,600 arcseconds; a sign is 30 degrees.

What The Site Does Not Do And Its Limits

The site does not make predictions. Astrology here is treated as a symbolic and reflective practice, not a science, and nothing on the site predicts events, health or money. It also does not calculate sidereal (Vedic) charts: the Lahiri ayanamsa used in Vedic astrology is about 24 degrees in 2026, so most placements in a sidereal chart fall one sign earlier than here. Chiron and the asteroids are not included.

Know the limits of your data. Without a birth time the chart is calculated for noon and omits the Rising sign, houses and Midheaven. The Moon moves about 12 to 15 degrees a day, so a noon Moon can be up to about 7 degrees off and may sit in a neighboring sign. The Ascendant moves about one degree every four minutes, so a wrong birth time is the biggest source of error in any chart, not the math.

Some placements carry little personal uniqueness. Uranus stays about 7 years in a sign, Neptune about 14, and Pluto 12 to 31 years, so astrologers read the outer planets as generational. Mercury never strays more than about 28 degrees from the Sun and Venus never more than about 47, so Mercury is always in the Sun's sign or one next to it, and Venus within two signs of it.

Privacy, Bookmarks And What Is Planned

Your birth details never reach our servers. They are kept in the page address after the # sign, which browsers do not send to any server, so you can bookmark a chart and return to it. Your Sun, Moon and Rising signs are remembered on your own device (browser localStorage) only, to show a shortcut back to your chart.

Birthplaces come from the GeoNames list of places with 5,000 or more inhabitants (CC BY 4.0), and time zones come from the IANA time zone database built into your browser, including historical offsets, daylight saving and wartime time.

One tip: large language models such as ChatGPT can explain placements you give them, but they are not ephemeris software, and asked to work out positions from a birth date they can state wrong signs or degrees. Calculate the chart first, then ask about the listed placements.

A deeper personal reading is planned: $10, written for one chart and one question. You can join an email list to hear when it opens. That list stores your email address, Sun, Moon and Rising sign, and your country, inferred from Cloudflare. Nothing else.
