Yod in Astrology: Two Quincunxes and a Sextile

← Back to Aspects

A yod is an aspect pattern made of three planets: two of them form a sextile (60°), and the third sits 150° from each, a double quincunx. Drawn on a chart wheel, it looks like a long, narrow triangle pointing at that third planet, which is called the apex. This guide covers the geometry, the definition these pages use, how to check for a yod by hand, why many yods are shared by people born around the same time, and how astrologers tend to read one.

A learning topic, not something the site calculates. The yod is built on the quincunx, a minor aspect, and the free birth chart does not calculate, list, flag or draw quincunxes. Its wheel can show the yod's base, because a sextile is one of the five major aspects it draws, but it shows neither of the two 150° legs and does not name the pattern. The yod figures below are offline calculations made with the same routines the free chart uses, not a hidden part of it. Ask the Astrologist can discuss yods as a concept, or a pattern whose degrees you have checked yourself, but it does not receive your planets' degrees and does not detect minor aspects or yods.

The geometry

Three planets, three contacts:

• The base: two planets about 60° apart, a sextile.
• The apex: a third planet about 150° from each base planet. Two quincunxes, often called the legs.
• Where the apex sits: opposite the middle of the base. If the base planets are at 0° and 60°, the apex falls near 210°, which is 150° from both.

The point directly opposite the apex lies at the midpoint of the base sextile. Some astrologers use the name "boomerang yod" when a fourth planet sits opposite the apex; these guides do not go further into that variant.

Some popular writing calls the yod the "Finger of God" or the "Finger of Fate". Those are nicknames and search terms only. They do not mean that a chart with a yod carries a divine mission, a fixed fate, a special destiny or a chosen status, and these pages make no such claims.

The definition these guides use

A yod on these pages needs all of the following, using the ten planets from the Sun to Pluto:

1. One apex, two legs. The same planet is quincunx to both base planets, and each quincunx is within this guide's 3° working band: |separation − 150| ≤ 3. The band and its sources are explained on the quincunx page.
2. A sextile base. The two base planets are in sextile within the site's existing 6° sextile orb, the same orb the free chart uses to draw a sextile.

Some astrologers want tighter orbs for every line of a pattern; these guides do not add a separate number for that. A useful piece of arithmetic: if both legs are within 3° of 150° and the base planets lie on either side of the apex's opposite point, the base cannot be more than 6° from 60°, so the two tests agree.

All distances are measured in zodiac longitude, using the shortest way round the circle. A leg still counts if it is out of sign, for example when one planet sits at the very end of a sign and the other at the very start, as long as the degrees are within the band. The chart angles (Ascendant, Midheaven and their opposite points) are not used as yod points here.

How to check for a yod

The method follows the same idea as how to find aspect patterns, with one extra step because the legs are not drawn.

1. Find the sextiles. Look for sextile lines on your free chart wheel, or list the sextile pairs from the planet table. Each one is a possible base.
2. Find the far point. Take the midpoint of the base pair (the middle of the 60° arc between them) and add 180°. That is roughly where an apex would have to be.
3. Look for a planet near it. Convert any planet near that far point to a longitude, from 0° Aries.
4. Measure both legs. Work out the separation from that planet to each base planet and check each one against the 3° band.
5. Confirm and record. If both legs pass, record the yod with the actual numbers, so anyone using a tighter or wider band can check it.
6. Check the birth time. If the Moon is part of the figure, the result needs a reliable time or a check across the whole possible birth window; otherwise it is not established. A leg close to 3° can also change within a day even without the Moon, so treat it as time-sensitive when the time is unknown. Houses, including the apex's house, need a reliable time. How to read a chart without a birth time explains what is still usable.

Other figures also rest on sextiles, such as the kite, and the T-square also points at one focal planet; the yod differs because its two long sides are quincunxes, which the wheel does not draw. Aspect patterns lists the named figures together.

Many yods are shared by a generation

The slowest planets can stay in sextile to each other for years or decades. While they do, every fast-moving planet that passes the far point of that sextile makes a yod with them. Neptune and Pluto have been within the 6° sextile orb for long stretches since the 1940s (see Neptune sextile Pluto), so many people born in the same weeks share a yod with a Neptune-Pluto base and a personal planet at the apex.

That matters for how a yod is read. A slow base is part of the background of a whole age group, as generational aspect patterns explains, and having a yod on such a base is not by itself evidence of anything unusual about the person. What is personal is which planet is at the apex, its sign, and with a reliable time its house.

Worked example: Noor

Noor is a fictional chart: London, 1 May 1985, 12:00 BST (11:00 UT). Positions were recalculated for this page with the production chart routines and rounded to 0.01°.

What the example shows:

• What the free chart shows. Noor's wheel draws the Neptune-Pluto sextile, because it is within the 6° sextile orb. It draws no line from Mars to Neptune or from Mars to Pluto, and nothing on the chart says "yod".
• The base is generational. Neptune and Pluto were in sextile for everyone born in London that day, and for a long stretch of years around it. Mars, the apex, is what ties this yod to a narrower group: checked once a day at 12:00 London time, both legs are inside 3° only from 27 April to 4 May 1985. The example is an ordinary one, picked because it is easy to check.
• The time barely matters here. There is no Moon in the figure. Recalculated across the whole London date, the Mars-Neptune leg runs from about 149.74° to 150.44°, the Mars-Pluto leg from about 149.26° to 149.97°, and the base stays at about 60.3°, all well inside the tests. Houses are not used, because the apex house would need a reliable time.

Reading a yod

The usual way to read a yod uses the same layers as any aspect: the planet says what is involved, the sign says how, and the house says where, the last only with a reliable birth time.

• The apex planet is usually read as the part of the person that is asked to keep adjusting between the two base planets, which already cooperate with each other through the sextile.
• The base pair describes two abilities or themes that work together fairly easily but do not connect smoothly with the apex.
• The signs show the style of each part. As with any single quincunx, the apex sign often shares no element, modality or polarity with the base signs, but an out-of-sign leg may.

In Noor's case, an astrologer might describe Mars in Gemini at the apex as drive and initiative that tend to keep re-tuning themselves between a Neptune theme and a Pluto theme that the whole age group shares. That is a tendency to explore, not a prediction of events or a statement of purpose. For each planet's own contribution, see quincunx aspects by planet.

Where to go next

The quincunx explains the single 150° contact and the 3° band in full, and minor aspects places it among the smaller angles. Aspect orbs covers the major-aspect orbs, and out-of-sign aspects the degree-versus-sign question. Planet meanings describes each planet, the methodology page lists what the free chart calculates, and the Aspects library has the other pattern guides.
