I get asked to explain birth charts to people who have never opened one, and I’ve watched enough friends bounce off the wheel to know: nobody needs a 20-minute lecture on the history of astrology first. They need to pull the chart, look at it, and know what they’re seeing.
So here’s the shortest version. Where to get your chart, what each part is, and how to start reading a placement without pretending you know things you don’t.
The video walks through this on screen. This post is the same walk-through in text — use them together or use whichever you prefer.
Step 1: get your birth data together
A basic chart needs your birth date.
A useful chart needs your birth date, your birth time, and your birth location. If you don’t know your time, the chart is still readable but the ascendant, the houses, and possibly the Moon are unreliable. That’s a lot to lose. So track down your birth time if you can — birth certificate, hospital record, ask family. It’s worth the effort.
Step 2: pick a tool
The square charts you see in the Co-Star app are fine as a first look, but they hide the aspects — the lines connecting planets — and aspects are half the read. Get a wheel chart as soon as you’re willing.
I use paid tools now. For free, use astro.com. It’s not pretty but it’s accurate and it’s free.
Go to astro.com → Charts and Calculations → Chart Drawings, Ascendant. Read the privacy notice, decide what you’re comfortable with, then enter your data. Name and gender are optional — put whatever you want, or leave them blank. Enter your date, your time (or leave unknown), and your birth city.
Hit continue. Your Sun, Moon, and rising sign appear at the top. Below that, the wheel.
Sit with the wheel for a second. This is a picture of the sky at the exact moment you arrived. As above, so below. I still find that amazing.
Step 3: know what each part of the wheel is
Four things are drawn on the wheel: planets, signs, houses, and aspects.
Planets. The Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. Plus a few points that behave like planets for our purposes: the North Node (looks like a horseshoe) and Chiron (looks like a skeleton key). Learn the glyphs so you can spot them on any chart. The Pluto glyph varies by site; it’s usually labeled in the legend.
If you don’t have your birth time, your Moon sign can be wrong. Anything sitting near 0 or 29 degrees of a sign on your day can be wrong. Everything else is fine.
Signs. The 12 zodiac signs run around the outside edge of the wheel. On astro.com, the wheel starts at whatever sign is on your ascendant. If you don’t have a birth time, most tools default to starting at Aries.
Houses. The 12 wedge-shaped slices are the houses. They count counterclockwise from the ascendant on the left. Each represents an area of life. Without an accurate birth time, the house positions are wrong. Another reason to find your time.
Ascendant. Labeled AC on the wheel, on the left. This is the sign that was rising on the horizon at your birth. It’s what most people mean when they say “rising sign,” and its accuracy depends entirely on your birth time.
Aspects. The lines drawn across the middle of the wheel. Angular relationships between planets. Red lines are usually squares, oppositions, or conjunctions. Blue lines are usually trines or sextiles. Aspects are mostly still accurate without a birth time, because planets move slowly. The Moon’s aspects are the exception.
There’s also an aspects table below the chart. I don’t use it — I read them off the wheel — but it’s there.
Step 4: read one placement
Basic astrology is a three-word sentence: this planet, in this sign, in this house.
Take Venus in the 2nd house in Aries. To read it, you say what you know about each part and let the sentence form.
Venus is love, beauty, art, pleasure, women, money as an object of desire.
Aries is impulsive, brave, first-out-the-gate, assertive, willing to act, not always weighing consequences.
The 2nd house is money, income, movable resources — the material things that sustain you.
Put the three together: this person may be impulsive with love and impulsive with money, and those two areas may show up as linked in their life. Impulse buys, quick attractions, fast decisions with the wallet or the heart.
That’s how it starts. It gets deeper — much deeper — once you start reading rulership, aspects, and dignity. But this is the doorway.
One more. Chiron in Gemini in the 5th. Chiron in Gemini is generational — a lot of your peers have it, so it’s not what makes you you. In general it can bring wounds around communication, or an illness or injury involving a sibling. In the 5th, it can show up around children or around pleasure. So: possibly a communication wound around kids, or difficulty accessing joy through speech, or something in the sibling story that plays out through your creative life.
What this doesn’t cover
I skipped a lot on purpose. Sect. Dignity. Rulership. Progressions. Transits. Solar returns. The Uranian bodies. Whether to use the whole sign house system or Placidus.
That’s real astrology. This post gets you looking at your chart with a rough map of what you’re seeing. Once you can name the parts, you can start reading the harder material.
