Dates are approximate. Near a boundary, calculate the Sun’s longitude for the year, birth time and time zone. The tropical signs are equal sectors beginning at the March equinox, not the unequal boundaries of astronomical constellations.
The twelve equal sectors of the tropical zodiac. This is not a map of constellation boundaries.
How the symbolism is used
Libra is the seventh sector of the tropical zodiac. Cardinal air is read through comparing positions and initiating an agreement. Harmony in this vocabulary does not require an absence of disagreement.
Libra is not equivalent to the seventh house. A planet in the sign can occupy different houses, and agreement between people is not established by a sign.
A placement in a constructed chart
A Moon at 8° Libra has a longitude of 188°. Its shorter distance from a Sun at 10° Aries is 178°, deviating by 2° from opposition. These are constructed positions, not a claim about a relationship.
These numbers explain a reading method; they are not a horoscope for a real person or a current forecast.

Questions about this lesson
Does the sign determine compatibility?
A Sun sign alone does not establish the quality or future of a relationship. Even astrological synastry compares more than two Sun signs.
