What these two are about together

The two lights, and the oldest question in a chart: whether what you are becoming and what you actually need are pulling in the same direction. Every tradition treats this pair as the most important relationship in a birth chart.

What a semi-square does

A semi-square is exactly half a square, and the tradition reads it as the same kind of friction at a smaller scale. Where a square describes a conflict that has to be dealt with, a semi-square describes the sort of persistent low-grade annoyance that never quite forces the issue and never quite goes away either.

How it reads

The self you are building and the comfort you require want different things. Read as the person who cannot rest while succeeding or succeed while resting, and traditionally as a tension carried from the two parents wanting different outcomes.

In practice

Read as irritation rather than demand. Kepler took the minor hard aspects seriously and much of the tradition since has treated them as real but secondary, which is the reading this site uses.

What to watch for

Accumulation. One semi-square is a footnote. Several of them to the same planet is the tradition's picture of somebody worn down by things too small to name.

The two planets

Sun: Identity, vitality and what you are becoming

Moon: Need, instinct and what settles you

Famous charts with sun semi-square moon

335 of the 13,000 documented charts on this site have it. The 24 best known are below. Every one is computed from that figure’s own birth data, with the source of the birth time stated on their page.

23 of these are marked approximate: the figure has a birth date and no birth time, and the Moon moves far enough in a day that the hour could change whether the aspect holds. The rest do not depend on the hour at all.

Sun and Moon at other angles

Sun and Moon also have a midpoint: the halfway point between them, read as a third place in the chart rather than as an angle between two.

Find this in your own chart

A reading like this only tells you what the pairing is associated with. Whether Sun and Moon actually make this angle in your chart depends on your birth date, time and place.
