Chart Summary

Point-by-Point

Take your chart into Taroscope

Import your Sun, Moon and Rising signs for a personal tarot reading. Your calculated placements, houses and aspects travel with the chart.

Generate your chart first. The import stays in this browser tab and does not include your birth date or birthplace.

House placements use your selected system: Placidus (the mainstream Western default) or Whole Sign. Historical timezone and daylight-saving rules are applied automatically from the selected birthplace. Planetary positions use astronomy-engine; lunar nodes are mean nodes and Chiron uses an osculating-orbit approximation.

About the Natal Chart Calculator

A natal chart maps the sky for a specific birth date, exact time and birthplace. The planets show different functions, signs describe how those functions operate, houses show where they become visible and aspects describe relationships between planets. This calculator also supports Placidus and Whole Sign houses, historical timezone handling, lunar nodes and Chiron for a chart closer to common professional formats.

How the method works

Enter the birth time exactly as recorded when possible. A difference of several minutes can shift the Ascendant and house cusps, especially at some latitudes. Begin with the Sun, Moon and Ascendant, then identify the rulers of the first and tenth houses. Read each planet as planet in sign in house, then add close aspects. If the time is unknown, treat the houses and Ascendant as uncertain rather than inventing precision.

History and tradition

Natal astrology grew from Mesopotamian observation and Hellenistic techniques that organized planets by zodiac, house and aspect. House systems developed in different periods. Whole Sign houses assign the entire rising sign to the first house, while Placidus divides the daily motion of the sky into time based arcs. Neither system changes a planets zodiac position. Modern practice often compares both while remaining consistent within a single interpretation.

Example reading

Example: Sun in Taurus in the tenth house, Moon in Pisces in the eighth house and Leo rising. The written reading is: a steady public identity and desire to build lasting work are visible, but private emotional life is highly receptive and needs protected recovery time. Leo rising makes expression noticeable. If the Sun sextiles the Moon, practical ambition and intuition can cooperate. The advice is to create visible work without treating constant visibility as emotional safety.

How to interpret the result

Avoid reducing the chart to one placement. A planet can be strengthened, challenged or redirected by its house ruler and aspects. The lunar nodes are often read as a developmental axis, while Chiron can describe a sensitive area that becomes a source of skill. Astrology is symbolic and interpretive. Use the chart to organize questions about pattern, timing and choice, not to diagnose health or declare an unchangeable fate.
