Square

skwair

latin: Quadratus · greek: Τετράγωνον (Tetragonon)

Definition

A square is the aspect you get when two planets are a quarter of the zodiac apart — an angle of 90°, the circle divided by four. It links signs of clashing elements that nonetheless share the same mode: cardinal, fixed, or mutable. The usual orb — how far from exact it can be — is 5–8°.

In Tradition

Most Western astrologers read the square as a challenging aspect, but a productive one: it tends to bring tension and friction, and with them the concentrated energy you need to push past obstacles and grow.

In Practice

A square in your chart points to an area of lasting tension — the kind that drives you to act and develop. As planets move over time, a square marks a crisis or turning point in a cycle; the first-quarter and last-quarter Moon are monthly Sun–Moon squares. When picking a good moment for something that needs to flow smoothly, astrologers tend to avoid squares. Two squares and an opposition closing into a single figure make a T-Square, one of the most commonly read patterns. A Saturn–Sun square recurs on average every 29.46 / 4 ≈ 7.37 years.

Historical Origin

Hellenistic sources name it tetragonon (τετράγωνον, 'four-cornered figure'), and classed it as harsh and inharmonious.
