Astrology / My Chart

Begin with the chart that every deeper reading depends on.

The natal chart records planetary positions for one birth moment. Start with the complete wheel, then move into the Big Three, chart rulers, elements, modalities, angles, retrogrades, and aspect patterns only where the calculation supports them.

Precision matters

An exact birth time and geocoded birthplace are needed for rising sign, Midheaven, house cusps, and house placements. When time is unknown, Lunar Letter should preserve planetary sign data while clearly removing unsupported precision.

One chart, consistent results

Big Three and paid natal reports must read from the same underlying chart object, so the Sun, Moon, rising sign, houses, and aspects never disagree across products.
