Yod Calculator

A Yod is three planets in a specific geometric circuit: two of them 60° apart (sextile, cooperative), each 150° from a third (quincunx, incompatible). The two base planets have a comfortable relationship, but both of them have a hard time integrating with the apex.

The nickname Finger of God reflects the feeling the pattern produces in the native: a sense that life keeps directing attention toward the apex planet's themes, often through circumstances the native didn't choose. Yods push adjustments. They rarely produce dramatic events, but they bend the trajectory of a life over time.

Start with the apex's sign and house. The sign tells you how the Yod's adjustments show up (cautious if Capricorn, emotional if Cancer, analytical if Virgo). The house tells you where in life (career, relationships, body, home).

Then look at what the apex planet rules in the chart. A Saturn apex quincunx Venus and Mars points to delays in the areas Saturn governs by house. A Moon apex reveals emotional recalibrations around the mother, home, or feeling-life.

The tool scans your chart for three-planet configurations where two planets form a sextile (60° apart, within 4° orb) and both form quincunxes (150° apart, within 3° orb) to a third body. When all three aspects close, the third planet is the apex and the configuration is a Yod. The check runs on the ten planets, Chiron, and the Ascendant, so apex-ASC Yods are included. Midheaven, IC, Descendant, and the lunar nodes are not in the detection set.

The calculator uses 4° on the sextile and 3° on the quincunxes as its fixed defaults, which is a moderate standard. Stricter conventions (2° on all three aspects) produce fewer valid Yods; looser conventions (5° or 6°) produce more. If a near-Yod in your chart sits just outside the default, run your full birth chart and check the exact orb on each aspect to see how close it actually is.

Different Yod calculators produce different answers for the same chart, and the disagreement is almost always about settings rather than math. Three things drive it. Orb tolerance is first: a calculator using 6° on the quincunx will flag patterns that a calculator using 2° will not. Second, some tools skip quincunxes entirely in their default aspect set, so the Yod cannot form no matter how close the geometry is. Third, body inclusion varies: this calculator includes the Ascendant but not the Midheaven, IC, Descendant, or lunar nodes, so tools that include those points will sometimes find Yods this one does not.

If this tool finds no Yod in a chart where another tool did, check which orbs and bodies the other calculator used. If this tool finds a Yod that a second tool missed, the same check applies in reverse. Pick one convention and stick with it rather than trying to reconcile tools with different defaults.

Read the apex first. The sign, house, and condition of the apex planet organize the whole pattern. Then check the two base planets and the sextile between them; they are the source of what keeps pressuring the apex. Check the orb on each quincunx separately: patterns with orbs under 3° feel more active than patterns with orbs over 5°.

For a full interpretation, open the learn page for your apex planet. The twelve Yod apex learn pages (Moon, Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto, North Node, Ascendant) each carry dedicated reading guidance plus by-house modules; note that this calculator detects planet and Ascendant apexes, while the North Node apex page is educational for charts where an astrologer has identified the pattern manually. If you also want to see other configurations in your chart, run the full aspect pattern scanner from the tools menu.
