What it is

Zodiacal releasing is a Hellenistic time-lord technique recovered from Vettius Valens and now widely used. It starts from a lot (usually Spirit for career and action, Fortune for body and circumstance) and releases periods of years, sign by sign, each with a fixed length taken from the traditional planetary years.

It nests. The first level divides a whole life into a handful of long chapters; the second divides each of those; the third and fourth go down to months and days. The technique's appeal is that the levels line up, a major transition at level one landing on the same date as one at level two is what practitioners look for.

The loosing of the bond is its most distinctive feature: when a period would run past the twelfth sign, the sequence jumps rather than continuing in order. These jumps are read as the sharpest transitions in the sequence, and they are the thing zodiacal releasing is best known for.

It needs an exact birth time. The lots it releases from are projected from the Ascendant, so an hour's error moves the starting point and everything downstream of it. Every period boundary in a lifetime shifts.

How Umbriel computes it

The releasing lot is computed first, with the day or night formula applied from actual sect, and the periods are then laid out using the traditional planetary years for each sign's ruler. The loosing of the bond is applied where the sequence would run past the twelfth sign, and each of the four levels is subdivided from its parent, not computed independently, so the levels stay in step, which is the whole point of looking at them together. Every boundary is converted to a real date in your own time zone.

Common questions

What is zodiacal releasing?

A Hellenistic timing technique that releases periods of years from a lot, usually Spirit or Fortune, dividing a life into nested chapters with fixed lengths from the traditional planetary years.

What is the loosing of the bond?

A jump in the sequence, which happens when a period would run past the twelfth sign. These are read as the sharpest transitions in the whole technique.

Should I release from Spirit or Fortune?

Spirit is traditionally used for career, action and the things you choose; Fortune for body, circumstance and what happens to you. Umbriel computes both rather than picking.

Do I need an exact birth time?

Yes. The lots are projected from the Ascendant, so an error in the birth time moves the starting point and every period boundary in the sequence with it.

How is zodiacal releasing different from profections?

Both are time-lord techniques, but profections move one sign per year in a simple twelve-year loop, while releasing uses variable period lengths from the planetary years and nests four levels deep. Profections are checkable in your head; releasing needs computing.

Is the zodiacal releasing calculator free?

Yes. All four levels, both lots, and the loosing-of-the-bond transitions, with no account.

Do I need an account or an email address?

No. There is no sign-up, no email capture and no free trial. Enter your details and the result is drawn in your own browser.
