Do you have a yod? And how rare is yours, really?
About 41 in 100 charts have a yod somewhere, so finding one is the easy part. What's worth knowing is how tight yours is. Enter your birth details and we'll measure it.
This is just one shape. Your whole chart shows you your birth chart drawn out, your Sun, Moon and rising sign, and the one shape in your chart that is most worth a closer look.

Here is the same check for the other shapes. You can open any of them to see yours in detail.

Would you like to look closer?
A reading is created from the whole of your chart, not just one shape. Your birth details are already here, so the form below takes you straight to a secure payment page.
It arrives in a private learning portal, with a chat function you can ask about it. If you are not sure what a reading looks like, you are welcome to read three chapters from a real one, which is my own.
What is a yod?
Two points in a chart sit a sextile (60°) apart, and both sit a quincunx (150°) from a third, called the apex. Drawn on the wheel it makes a long, narrow triangle, which is why it's also called the Finger of God.
Two parts of you that work easily together both lean, at an awkward angle, on a third. Astrologers call this shape a yod. It turns up in a good share of charts. It's quieter than a T-square: it feels less like a pull between opposites and more like being asked to keep adjusting.
The part at the point where the two lines meet often carries a sense of being asked for something specific that's hard to name, and it can take years to name it. People with a tight yod often describe feeling slightly out of step, fitting a role almost but not quite. The adjustment tends to stop feeling like a flaw once it's seen as the thing the shape is asking for, even if the answer doesn't fit any role you've been offered.
How common is a yod?
Most yod calculators call it rare, but at the orbs usually allowed it isn't. Here's how often it turns up, measured across 100,000 random birth charts from 1930 to 2025:
| Yod | Charts with one |
|---|---|
| Any yod, at the orbs usually allowed | 41 in 100 |
| Every side within 2° | 26 in 100 |
| Every side within 1° | 8 in 100 |
| Every side within half a degree | 2 in 100 |
This table is about single yods, by their loosest side; a double yod or interlocking yods count as having one here. If your result shows a double or interlocking yod, its figure measures the pair or the whole structure instead, which is why it can be much rarer than this table suggests.
Questions
Is a yod rare?
Not at the usual orbs. Measured across 100,000 random charts, about 41 in 100 have a yod somewhere. A tight one is another matter, though, because only about 2 in 100 have a yod with every side within half a degree. That's why this calculator measures yours instead of just finding it.
What does "1 in X charts have one this strong" mean?
We scored a million random charts the same way as yours and compared your strongest yod pattern with charts that have the same kind. For a single yod the score is how tight its two long sides are; for a double yod, how exactly the two yods' points face each other; for interlocking yods, how many yods share points. The figure is the share of charts with that kind of pattern at least as strong as yours. Below about 1 in 20 we use a word instead of a number, because a figure that small doesn't tell you much.
What if I don't know my birth time?
The calculator still works, but a yod that involves your Moon or your rising sign can't be placed, because both move too far in a day. If that's possible for your chart, it tells you it can't be sure, rather than saying no.
