Free natal chart calculator

Your birth chart, drawn for real.

Real ecliptic positions for the ten classical bodies, your rising sign when you know your birth time, twelve equal houses, and every major aspect — drawn as a wheel. No signup. No saving. Just the chart.

Birth time

Without birth time, your sun, planets, and most aspects compute correctly. Rising sign and houses need the exact hour and a city.

About natal charts

A map of the sky at your first breath

A natal chart records where ten bodies — Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto — sat along the ecliptic at the moment you were born. The ecliptic is the path the Sun appears to trace through the zodiac over a year. The other planets follow it closely, each moving at its own speed.

Each body lands in one of twelve signs. Your Sun sign, the one most people know, reflects your core sense of self. Your Moon sign describes how you handle feeling — what you need when the day goes sideways. Mercury shapes how you think and argue. Venus, how you love and what you find beautiful. Mars, what makes you fight and what makes you move.

When birth time is known, the chart also shows twelve houses and a rising sign. The rising sign — the zodiac degree crossing the eastern horizon at your birth — shapes first impressions and the way you carry yourself before you’ve said a word. Houses map the wheel to areas of life: work, relationships, home, money, health, reputation.

How to use this calculator

Enter your birth date. That alone gives you accurate signs for all ten planets and their aspects to one another. If you know the time you were born, toggle “Known” and add your latitude, longitude, and timezone — you’ll get houses, a rising sign, and the full wheel diagram. Check a birth certificate or ask a parent; even an approximate hour helps.

Reading your results

The wheel places each planet in its sign and house. Below it, a table lists the exact degree for every placement. The aspects section shows angular relationships between planets, sorted by tightness: conjunctions (0°), trines (120°), squares (90°), oppositions (180°), and sextiles (60°). Tighter orbs mean stronger connections between the two bodies involved.

Frequently asked questions

Do I need my exact birth time?
No. Without it you still get all ten planetary signs and most aspects. Birth time adds your rising sign and house placements. If you have an approximate hour, use it — an estimate within thirty minutes still produces useful house data.
How accurate is this?
Planetary positions are computed from ecliptic math to degree-level precision. The results match what you’d get from professional chart software. We use the same astronomical formulas that underpin tools used by working astrologers.
What’s the difference between a sun sign and a rising sign?
Your sun sign develops over a lifetime — it’s the core identity you grow into. Your rising sign is more immediate: how you present to strangers, the first read people get when you walk in. Most people recognize both in themselves once they know what to look for.
