The horary window

A horary window is the dated stretch of time inside which a reading judges a matter ready to move. It is drawn from the chart of the question, chiefly from the Moon's next application converted to days, weeks or months by the classical timing table, and then narrowed by the running periods of the person's own charts. It has a start and an end, it can be moved by facts the chart asks about, and it can be refused entirely.

How a window is drawn

The horary chart supplies the clock. The Moon's distance in degrees to the aspect that carries the matter becomes a count of days, weeks or months, according to the sign and house it sits in. That raw stretch is then read against the slower calendars of the person's own charts, the year's profected house, the running Vimshottari period, the current pillar, and where those calendars hold the door open, the window stands. A window is never narrower than a fortnight unless something specific closes it early.

What can move or close it

Two things move a window honestly. The person's answers to the chart's own questions can delay its opening or cap its end, when a fact on the ground says the sky's earliest date is not yet livable. And exclusions cut into it: a stretch such as a Venus retrograde is not a time to begin the very matter Venus rules, so the window is trimmed around it and the document says why. When the timing testimony is too weak to stand on, no window is named at all. A reading that invents a date where the chart offers none is decorating a guess.

Why windows are honest in a way predictions are not

A window is falsifiable. It commits to a stretch of dates, it names the sources that drew it, and when it closes, it closes. That is the difference between a reading you can hold to its word and a horoscope that is never wrong because it never says anything. If the window passes and the matter has not moved, the honest next step is a fresh question in its new moment, not a defense of the old chart.
