Key facts
A free astrology chart (also called a birth chart or natal chart) maps the Sun, Moon and planets across the tropical zodiac for your exact birth moment. You need your birth date, your birth time and your birth city for a full chart with Rising sign and houses; with a date alone you still get every planet sign. This tool computes real planetary positions locally in your browser — free, private and without sign-up.

A free astrology chart is a snapshot of the sky at the exact moment you were born, seen from the place you were born. Astrologers read that snapshot as a symbolic map: where each planet sat in the zodiac, which of the twelve houses it occupied, and which angles the planets formed to each other. This free astrology chart page generates that map honestly — if you do not know your birth time, it says so instead of inventing an Ascendant.
01
What a free astrology chart shows
Every free astrology chart contains the same three layers. The first layer is the planets: the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, each sitting at an exact ecliptic longitude measured in degrees. The second layer is the signs: that longitude maps onto one of the twelve zodiac signs, from Aries at 0° through Pisces at 330°–360°. The third layer is the houses: twelve sectors of the sky counted from your Ascendant, which is the zodiac degree rising on the eastern horizon at your birth place and time.
When people talk about "getting my free astrology chart done", this is the object they mean. The chart wheel you see above is the classic two-dimensional rendering: signs on the outer ring, planets placed at their true longitudes, aspect lines drawn between planets that form exact angles. Reading a free astrology chart is simply learning to walk those three layers in order — planets first, signs second, houses third, aspects last.
Planet placements: each planet in a zodiac sign at a specific degree, plus retrograde flags — the backbone of any free astrology chart.
The Big Three: your Sun sign, Moon sign and Rising sign (Ascendant).
House positions: which of the twelve life departments each planet occupied — needs a birth time.
Major aspects: conjunctions, sextiles, squares, trines and oppositions between planets.
Certainty notes: what changes if your birth time is missing or approximate.
02
How this free astrology chart is calculated
Your free astrology chart begins with one conversion: birth date and local time become a single UTC instant using the IANA time-zone rules for your birth city — including historical daylight-saving quirks, which is why the form asks for a city rather than guessing your zone. From that instant, the open-source Astronomy Engine computes the geocentric apparent position of each body: not a lookup table of monthly signs, but real orbital mathematics accurate to about one arc-minute. Longitudes are then projected onto the tropical zodiac, the standard frame used by western astrology.
The Ascendant and Midheaven come from your coordinates and the local sidereal time at your birth moment, and the houses are derived from them using the Whole Sign system by default. If two planets sit within a few degrees of an exact 0°, 60°, 90°, 120° or 180° angle, the aspect is reported with its orb — the deviation from perfect. Everything a free astrology chart claims here can be checked against any published ephemeris, and the Methodology page documents every constant behind the free astrology chart math.
Tropical zodiac, honestly labelled
This free astrology chart tool uses the tropical zodiac — the frame tied to the equinoxes that western astrology uses — and says so. Sidereal calculations used in Vedic astrology apply a different reference; if you need that tradition, look for a dedicated sidereal tool rather than assuming this chart matches it.
One engine behind this free astrology chart site
The same calculation core that draws this free astrology chart also powers the Saturn return calculator, the transit chart, the houses explorer and the astrocartography map linked below — one shared engine keeps every free astrology chart result consistent. That is deliberate: when every page shares one engine, your Venus sign here can never contradict your Venus sign there.
03
How to read your free astrology chart wheel
Start at the left of the wheel: the horizontal line pointing left marks the Ascendant, and the zodiac proceeds counterclockwise from it around your free astrology chart. Glyphs on the outer ring are the twelve signs; the small circles holding planet symbols sit at their true longitudes, nudged apart only far enough to stay readable — the tick marks show the exact degree. Inside, colored chords connect planets in aspect: violet for conjunctions, green for sextiles, red for squares, blue for trines and orange for oppositions.
Hover any planet for its full position. The table below the wheel lists every placement in plain text, and the copy button lets you keep your free astrology chart summary anywhere you like — that portability is part of what makes this a genuinely free astrology chart rather than a screenshot you cannot keep. If your chart shows a warning banner instead of an Ascendant, that is the system being honest about a missing birth time — add the time and re-run to unlock angles and houses.
04
Free astrology chart with unknown birth time
Plenty of people do not know their birth time, and most free astrology chart sites quietly pretend noon. This free astrology chart does not. Here, a chart without a time still computes every planet sign (the Sun through Saturn barely move in a day) but hides the Rising sign, Midheaven and houses, because those genuinely cannot be derived. The Moon is flagged when it could change signs during your birth day — a real possibility, since it travels roughly 13° daily.
To complete your free astrology chart, find your birth time from a birth certificate, a hospital record or a family member, then re-enter it with your city. Even an approximate window ("sometime in the morning") narrows the Ascendant from the whole zodiac to a few signs, and the tool labels the result as approximate instead of exact.
05
Free astrology chart vs paid chart services
A free astrology chart here is not a demo funnel: the wheel, the placements, the aspects and the export are the whole product, and no paywall appears after you generate your free astrology chart. Paid chart services typically sell long-form written interpretations, printed booklets or subscription forecasts. Those can be lovely, but the calculation inside a free astrology chart — the positions, angles and aspects — is astronomy that belongs to everyone, and this site keeps the free astrology chart verifiable.
The difference worth attention in any free astrology chart is interpretation quality. This tool separates what it computed from what tradition says it means, so you always know which half you are reading. For the meaning side, start with the natal chart reading page; for the raw positions, the astrology calculator page gives you a clean table view.
Frequently asked questions
Is this free astrology chart really free?
Yes. Generating the wheel, placements, houses and aspects costs nothing, needs no account and has no result hidden behind a payment screen. The site runs on one shared calculation engine and stays free.
What do I need to generate a complete free astrology chart?
Your birth date, your exact birth time and your birth city. The date alone gives planet signs; the time and city additionally unlock the Rising sign, Midheaven and the twelve houses, because those depend on the rotation of the Earth during your birth day.
Why is my Rising sign missing?
Because no birth time (or no birth place) was given. The Ascendant advances roughly one degree every four minutes, so it cannot be guessed from a date. Add the time and city, and the free astrology chart will compute your Rising sign exactly.
How accurate are the planet positions?
Positions come from Astronomy Engine, an open-source ephemeris accurate to about one arc-minute for modern dates — far tighter than the degree-level precision astrology uses. Time-zone handling covers historical daylight-saving changes for the city you select.
Is my birth data stored when I make a free astrology chart?
No. All math behind your free astrology chart runs locally in your browser, nothing is uploaded, and the optional memory of your inputs lives only in this tab and disappears when you close it.
