Free natal chart in seconds, with Sun, Moon and Rising
Calculate your birth chart and natal chart from birth date, local birth time, and city. This free calculator returns your Sun sign, Moon sign, and Rising sign (ascendant), plus planetary positions, equal house cusps, and major aspects.
Unlike a sun-sign-only lookup, you get an SVG chart wheel, Big 3 synthesis, aspect insights, and links to placement guides, built for beginners and chart readers who want accurate tropical zodiac results.
What this tool does: calculates your sun sign from birth date; with birth time and a city from autocomplete, it also computes moon sign, rising sign, a chart wheel, house cusps, planetary positions, and major aspects.
Sun, Moon & Rising
Your Big 3 with synthesis and links to sign guides.
10 planet placements
Sun through Pluto with sign, degree, and house when available.
Major aspects
Tightest conjunctions, trines, squares, and more with plain-language notes.

Birth chart example
Illustration for 15 June 1990, 14:30, Belgrade: your chart uses your own birth data after you calculate.
| Placement | Sign |
|---|---|
| Sun | Gemini |
| Moon | Pisces |
| Rising (ASC) | Libra |
Gemini Sun brings curiosity, verbal agility, and a mind that connects ideas quickly. In a natal chart, the Sun describes core identity and life direction: what you are growing toward, not just surface personality.
Pisces Moon adds empathy, imagination, and emotional depth beneath the mental pace of Gemini. The Moon sign describes private needs, instincts, and how you process feeling when life gets personal.
Libra Rising softens first impressions with charm, balance, and social grace. The ascendant shapes how others meet you before they know your Sun or Moon, and anchors equal house cusps in this calculator.
Together this Big 3 reads as quick-minded curiosity (Gemini) with a sensitive inner world (Pisces) presented through diplomatic poise (Libra). A tight aspect (for example Venus trine Jupiter) would add another layer in your real results. Explore sun signs, moon signs, and rising signs for deeper guides.
Personalized output
Free birth chart reading
This is not a generic sun-sign blurb. After you submit your birth details, Astrologylo builds a chart-specific reading: your Big 3 synthesis, strongest natal aspects, element and modality balance, and links to placement guides you can open next. Add birth time and a city from autocomplete for the full wheel, houses, and planets.
- Big 3 interpretation when time and city are set
- Top aspect insights ranked by orb
- Placement links to deeper guides on your chart
- Sun sign from date alone if birth time is unknown
Sample reading (illustration)
Suppose your chart returns Gemini Sun, Pisces Moon, and Libra Rising. A synthesis might read:
Your Gemini Sun brings curiosity and verbal agility, while Pisces Moon adds empathy beneath the surface. Libra Rising softens first impressions with charm and balance: people may read you as diplomatic before they notice how quickly your mind moves.
The same result page also surfaces a tight aspect (for example, Venus trine Jupiter (orb 1.2°)) with a plain-language note that generosity in love and social confidence tend to reinforce each other in your chart. That is how natal interpretation works here: placements first, then the strongest links between them, not a one-size-fits-all paragraph.
Your reading uses your birth data. The example wheel above shows the format; your synthesis and aspects are generated after you calculate.
Step-by-step guide
How to read your birth chart
A birth chart (natal chart) is a map of the sky at your exact birth moment: which zodiac signs the Sun, Moon, and planets occupied, how they connect through aspects, and which life topics each placement emphasizes through houses. You do not need to decode every symbol on day one. Most astrologers start with a short reading order: core identity, personal planets, houses, then the tightest aspect links.
This guide matches how Astrologylo presents results after you use the free birth chart calculator. Calculate first if you have not already, then walk through the steps below with your Sun, Moon, Rising, planet table, and aspect list open beside you.
-
1. Calculate your chart with the right birth data
Enter birth date for your sun sign. For moon sign, rising sign, the chart wheel, house cusps, and aspects, add local birth time and choose your city from the autocomplete list so timezone and coordinates are accurate. Without birth time you still get a valid sun sign layer, but moon, rising, and houses stay unreliable. See why birth time matters before you interpret those placements.
-
2. Start with the Big 3: Sun, Moon, and Rising
Sun sign describes core identity, ego, and life direction. It is what most horoscopes mean when they say "your sign," because it comes from birth date alone. Moon sign describes private emotions, instincts, and what helps you feel safe. Rising sign (Ascendant) describes first impressions, personal style, and how you enter new situations.
Read them as three voices, not three competing labels. Your synthesis paragraph on the results page blends these layers into one narrative. For sign-by-sign depth, open the zodiac hub, moon sign guides, or rising sign guides that match your placements.
-
3. Add personal planets: Mercury, Venus, and Mars
After the Big 3, scan the inner planets in your results table. Mercury is how you think, speak, and process information. Venus is love style, values, and what you find beautiful or worth pursuing. Mars is drive, anger, courage, and how you pursue goals. These three shape daily personality more than outer planets do.
Jupiter and Saturn add growth themes and structure. Uranus, Neptune, and Pluto move slowly and often describe generational tones in your chart rather than traits you notice every morning. Browse planet guides when you want full meanings for each placement in sign and house.
-
4. Note house topics (when birth time is set)
Houses show where chart themes play out: self (1st), money and values (2nd), communication (3rd), home (4th), creativity and romance (5th), work and health (6th), partnerships (7th), shared resources (8th), beliefs and travel (9th), career and reputation (10th), community (11th), and inner life (12th). Astrologylo uses equal houses: the Ascendant starts the 1st house and each house spans 30°. House numbers may differ from Placidus charts on other sites even when planet signs match.
Beginners can ask one question per house: "What part of life does this planet emphasize?" A Venus in the 10th house story differs from Venus in the 5th even when Venus shares the same zodiac sign. Houses require birth time, so skip this step until your time and city are entered.
-
5. Read aspects by orb: tight links first
Aspects are angles between planets. Conjunctions (0°) blend energies. Sextiles (60°) and trines (120°) often feel cooperative. Squares (90°) and oppositions (180°) create tension that can motivate growth or friction, depending on awareness. Each aspect in your results shows an orb: how far the aspect is from exact. Smaller orbs usually matter more.
Do not try to interpret twenty aspects at once. Read the top three to five tightest links on your results page, then notice whether they reinforce your Big 3 story or add a twist (for example, confident Sun themes tempered by a Saturn square). Our aspect insights rank by orb so the strongest patterns surface first. For aspect vocabulary, see natal chart basics.
-
6. Use the chart wheel as a visual check
The SVG wheel shows the same data as the tables: zodiac ring on the outside, house cusps inside, planet glyphs placed by degree. The Ascendant (ASC) sits on the left horizon line in our wheel format. Use the wheel to see clusters: many planets in one sign, a loaded 7th house, or a striking opposition across the chart.
If you are new to wheels, read the tables first, then glance at the wheel to confirm what you already learned. The example chart on this page shows the layout before you calculate.
Common beginner mistakes
- Stopping at sun sign while calling it a "full chart" reading.
- Treating moon or rising as optional when birth time is available.
- Labeling squares or oppositions as purely "bad" instead of dynamic tension.
- Comparing your equal-house chart to a friend's Placidus chart without noting the house system difference.
What to explore next
Use placement links on your results page to open deeper guides for each planet and sign. For relationship context, compare sun signs on our compatibility hub, then layer moon and Venus themes from both charts when you have birth times. Daily horoscopes interpret transits against your sun sign; your natal chart explains the baseline they respond to.
Chart reading is cumulative. Return after you learn one planet or house topic, add a new layer, and let the picture deepen over time rather than in one sitting.

How to calculate your birth chart
Enter birth date for your sun sign. For moon sign, rising sign, houses, and aspects, add local birth time and pick your city from the autocomplete list so we can convert to UTC and use accurate coordinates. Without birth time you still get your sun sign; moon, rising, and houses need a time.
Big 3
What your Sun, Moon & Rising mean
Sun is core identity and life direction. Moon is private emotion and comfort needs. Rising (Ascendant) is outward style and first impressions. Together they form the foundation most astrologers read first.

Birth chart vs horoscope
A birth chart is fixed to your birth moment: a snapshot of placements and aspects you keep for life. A daily horoscope interprets where planets are now and how those transits might color your sun sign today. Use this calculator for your natal blueprint, then check daily forecasts for timing. For planet-by-planet depth, browse planet guides.
Before you calculate
Why birth time matters
Your sun sign comes from birth date alone: the Sun spends roughly a month in each zodiac sign, so month and day are enough for that layer. A full natal chart is different: it is a snapshot of the sky at one exact minute, anchored to a specific place on Earth. That is why serious chart work asks for birth time and birth city, not just the calendar date.
Time matters most for your rising sign (Ascendant). The sign on the eastern horizon changes about every two hours. Even a 10 to 15 minute error can shift the ascendant or move planets near house cusps. Rising sign shapes first impressions, outward style, and (in house-based work) which life topics each planet emphasizes. Without birth time, rising sign and house placements are unreliable no matter how accurate your city is.
The Moon moves faster than the Sun: it changes zodiac signs every two to three days, and can change sign within a single calendar day. On some birthdays the Moon stays in one sign from morning to night; on others it crosses a cusp. That is why moon sign often needs time, not just date. Mercury, Venus, and Mars move more slowly than the Moon but still benefit from an exact birth moment when you want degree-level accuracy and tight aspect orbs.
When you add local birth time and select a city from autocomplete, Astrologylo converts your clock time to UTC, applies the correct timezone and coordinates, and computes moon sign, rising sign, equal house cusps, planetary positions, and major aspects. If you do not know your time, you can still calculate your sun sign, but you will not get moon, rising, houses, or the chart wheel until you have a time to enter. Check a birth certificate, hospital record, or family memory; even an approximate time is more useful than none. Read our methodology for how UTC conversion and equal houses work behind the calculator.
Methodology
How this calculator works
Astrologylo uses the Western tropical zodiac. Planetary longitudes for the Sun, Moon, and planets through Pluto (Uranus, Neptune, and Pluto included). When you enter birth time and select a city from autocomplete, local clock time is converted to UTC using the IANA timezone stored with that city record (including daylight saving rules where applicable).
Latitude and longitude from the same city record anchor the Ascendant (rising sign) and equal house cusps: each house spans 30° of ecliptic longitude from the Ascendant, computed in PHP. Major natal aspects (conjunction, sextile, square, trine, opposition) are derived from those planetary longitudes with standard orbs. Results include an SVG chart wheel plus tables for planets, houses, and aspects.
This tool uses equal houses, not Placidus or whole sign. Small differences (under about a minute of arc) can still appear versus other calculators because of rounding, house system, or city coordinate choices. Accuracy depends on birth time precision and picking the correct city from the list. Rising sign and fast-moving placements can shift within minutes. This tool is for self-reflection and education, not medical, legal, or financial advice.
The Big 3 in your birth chart
Sun, Moon, and Rising are the three placements most readers start with. This calculator returns all three when you add birth time and city.
Sun sign
Ego, core identity, and life purpose. Determined by birth date only. Use the calculator above.
Moon sign
Private emotions, instincts, and comfort needs. Usually needs birth date and time.
Moon sign hub →Rising sign
First impressions, outward style, and ascendant. Needs date, time, and birth city.

What does this birth chart calculator show?
This tool finds your sun sign from birth date. With birth time and a city from the autocomplete list, it also calculates moon sign, rising sign (ascendant), equal house cusps, an SVG chart wheel, planetary positions (Sun through Pluto), and major aspects.
What do I need for a full birth chart?
A complete natal chart needs your birth date, exact birth time (as precise as possible), and birth city for timezone and geographic coordinates. Birth time is especially important for the rising sign and house placements; the Moon can shift signs within a single day. Read natal chart basics for a full overview.
What is the difference between sun, moon, and rising sign?
Sun sign is core identity and ego, determined by birth date alone. Moon sign is private emotions and instincts, needs date and usually time. Rising sign (ascendant) is first impressions and outward style, needs date, time, and birth location. The rising sign sits on the eastern horizon at birth and anchors house interpretation in full natal chart work; it moves quickly, so even a 10 to 15 minute time error can change the ascendant.
What if I do not know or cannot trust my birth time?
You can still get your sun sign from birth date alone. Without birth time, moon sign and rising sign are unreliable: the Moon can change signs within a day (sometimes it stays in one sign all day, but often you need time to be sure), and the ascendant changes every few hours. If your time is approximate or wrong, treat moon, rising, and house placements as likely ranges; a few minutes can shift the ascendant or move planets near house cusps. This calculator asks for birth time when you want full natal data rather than using a noon default.
How accurate is this birth chart calculator?
Sun sign from birth date is reliable for standard Western tropical dates. Moon sign, rising sign, and planetary positions depend on exact birth time, the correct city from autocomplete, and ephemeris precision. We validated sample charts against multiple external calculators; small differences (under about a minute of arc) can still appear from rounding or house systems. Free does not mean random: this tool uses published ephemeris data and documents its setup in methodology. Treat results as educational self-reflection, not scientific proof or professional advice.
In what order should I read my birth chart?
Start with the Big 3 (Sun, Moon, Rising), then personal planets (Mercury, Venus, Mars), then houses when birth time is set, then the tightest aspects by orb. Use the chart wheel as a visual check after you understand the tables. See our how to read your birth chart guide for the full step-by-step walkthrough.
Why do different birth chart calculators show different results?
Sites may use different ephemeris sources, house systems, time zone rules, city coordinates, or zodiac (tropical vs sidereal). A one-minute birth time difference can change the ascendant. This calculator uses the tropical zodiac and equal houses: the Ascendant starts the 1st house and each house spans 30°. House numbers may differ from Placidus-default charts while planet signs and degrees should usually match within about a degree. See methodology for ephemeris.fyi, timezone handling, and coordinate details. The example chart shows the equal-house wheel format.
