MODERNA modern technique: twentieth-century astrology.
- What you'll needYour birth date, time and place, and three or more dated moments from your life (a move, a wedding, a diagnosis, the day something began)
- What you getA table of ten clocks (transits, solar arc, secondary progressions, the progressed Moon, annual profections, Zodiacal Releasing from Spirit and from Fortune, firdaria, primary directions, BaZi luck pillars): how many of your days each struck on, what a random day scores, the expected hits, and the odds against chance; plus which clock struck on which day

What it is
Most astrology asks you to trust a technique before it has earned it. The Jury turns that round. You give it the days your life actually turned, with hard edges: the move, the wedding, the diagnosis, the loss, the day the job began. It then asks each timing technique in Umbriel's cabinet whether it was striking on that day, by a rule fixed in advance: a transit or a solar-arc contact within one degree, a progressed Moon changing sign within 45 days, a profected sign holding one of your planets, a Zodiacal Releasing period turning within 60 days, a firdaria lord changing within 90 days, a primary direction within five months, a BaZi luck pillar turning within six months.

The honest half is the base rate. Something is always striking somewhere: about a hundred directions land in a lifetime, and five slow planets make hard aspects to four points more often than you would think. So the Jury also samples 120 days spread evenly across your life so far and puts them to exactly the same test. That share is what a random day scores. Multiply it by your number of events and you have the hits luck alone would expect; the binomial odds of at least your actual count at that rate are the odds against chance. Every row prints all three.
Ten clocks are asked at once, so one of them reaches one-in-twenty by luck about half the time. A clock is only said to have beaten chance when its odds clear one in twenty divided by ten, one in two hundred, and the page says so in words. With fewer than five events nothing can clear that bar, whatever the table shows, and the page says that too.
A clock that clears the bar has fitted your past. That is not the same as reading your future, and the page never claims it is. What it gives you is the thing nobody else offers: a measured answer to which of these ancient and modern timing systems has been keeping time with your own life, in your own dates, with luck's share printed beside it.
Every row links to the full tool, so a clock that struck can be opened for the day in question: the transit, the direction, the releasing period, the luck pillar. The Jury lives inside Your Arc, the life timeline where your moments already sit beside your Saturn returns and progressed Moon, and it re-runs the moment you add a date.

How Umbriel computes it
Deeper.a cup-of-tea read
Each of the ten clocks is asked one yes-or-no question per date, by a rule fixed in the code before any of your events are read: a transit from Jupiter, Saturn, Uranus, Neptune or Pluto within 1° of a conjunction, square or opposition to your Sun, Moon, Ascendant or Midheaven; a solar-arc or progressed contact to the same four points within 1°; the progressed Moon crossing a sign boundary within 45 days either side; the profected sign of that year of life holding one of your seven traditional planets; a Zodiacal Releasing period beginning within 60 days, or the date falling inside a marked period; a firdaria lord or sub-lord changing hands within 90 days; a primary direction landing within five months; a BaZi luck pillar turning within six months. The base rate is MEASURED, not assumed, and measured on your own life: 120 days are laid out evenly across the span from your first birthday to the later of today and your last event — a grid, not a random draw, so the sample cannot cluster — and every one of them is put through exactly the same test. The share that strike is what a random day scores; multiplied by your number of events it gives the hits luck alone would expect, and the binomial tail at that rate gives the odds. A CLOCK THAT CANNOT MISS IS NOT A CLOCK, and one of them could not. Measured on 6 September 2026, solar arc with every arc planet against six targets struck on 88% of random days: a row that would have printed as a triumph on any life whatsoever. It was cut to the arcs of the Sun, Moon, Saturn, Ascendant and Midheaven against the four lights and angles, which scores about 30%, and the transit row is the five slow planets for the same reason. Because ten clocks are asked at once, the bar a clock must clear is one in twenty divided by ten — one in two hundred — and the page says that in words rather than in a footnote. The BaZi row pools the luck-pillar boundaries for BOTH directions of the classical rule, because the direction depends on a gender the Jury never asks for; that makes the row easier to strike, its measured base rate rises to match, and the odds column absorbs the difference. That is the whole argument for measuring the base rate instead of assuming one.

Common questions
How many life events do I need?
Three to run it; five or more to separate a clock from luck. Dates you are certain of matter more than many dates.
What does 'random day scores 38%' mean?
That if you picked a day of your life at random, that technique would be striking on it 38% of the time by its own rule. Your hits are judged against that, not against zero.
Why is the bar 1 in 200 and not 1 in 20?
Because ten techniques are asked at once. Give ten fair coins enough throws and one looks lucky; dividing one-in-twenty by ten keeps the verdict honest.
Does a clock that beats chance predict my future?
No. It has fitted your past. Umbriel says so on the page, every time, because the difference is the whole point.

Yes: all ten clocks, the base rates and the odds, inside Your Arc, with no account.
