Natal Chart

Your Western-astrology birth chart from date, time, and place of birth — planets, houses, and signs.

📖 How to read Natal Chart

A natal chart (birth chart) is a circular map of where the planets stood in the sky at the moment you were born. By reading which sign and house (area of life) each of the ten bodies — Sun, Moon, Mercury, Venus, Mars, and the rest — occupies, and which aspects they form with one another, you get the big picture of your temperament, relationships, work, and talents. An accurate chart needs your birth time and birthplace along with the date, because the Ascendant and house boundaries are highly sensitive to the time of birth.

  1. Enter your birth date, time (to the minute if possible), and birthplace.
  2. Look over the circular chart — the band of twelve signs and the planet symbols placed on it.
  3. Tap a planet to see its sign, house, degree, and the aspects it forms with other planets.
  4. Start with the Big 3 — Sun (self), Moon (emotions), Ascendant (first impressions) — and the overall flow falls into place.

❓ Frequently asked questions

Can I still get a chart without my birth time?

Planet signs like the Sun and Moon are mostly accurate without a time, but the Ascendant, houses, and some sensitive points depend on it. Without a time, the chart is calculated for noon, and it's best to leave the Ascendant and houses out of your reading.

Is this the same as 'my sign'?

The sign people usually mean is just your Sun sign — the one set by your birth date. A natal chart reads all ten bodies' signs, houses, and aspects together, so it gives a far fuller, more layered picture.

What are houses?

Houses divide the sky into twelve 'areas of life'. House 1 is self and appearance, house 7 is relationships and partnership, house 10 is work and public standing — which house a planet sits in shows the stage of life where that energy plays out.

Why do aspects matter?

The angles between two planets (0°, 60°, 90°, 120°, 180°, and so on) show whether they cooperate or clash. Harmonious aspects (trine, sextile) point to natural talents; tense ones (square, opposition) point to growth work.

Which house system should I pick (Placidus or Whole Sign)?

They're different ways of drawing house boundaries — modern Western astrology often uses Placidus, while traditional and Hellenistic practice favors Whole Sign. You can choose in the options; your planets' signs don't change either way.
