What This Is
A brief strike against the self. When the hourly branch clashes the day-pillar branch by 六冲, the two-hour window surfaces conflict in the body-mind, in travel, in the action at hand. This is the finest resolution of timing the system holds — a single 时辰, two hours, where a small disturbance to the self comes due. Where the day names a date, the hour names the very interval.
Its force is the slightest of all the clash-scales, but its precision is the greatest, which is why it belongs above all to the selection of hours.
When It Fires
It fires when the hourly branch forms a 六冲 with the day-pillar branch, a daily occurrence at the same two-hour window. Its depth is gauged by company: an hourly clash alone is a minor passing friction, while one that coincides with a 流日, 流月, or 流年 clash on the same point marks the precise hour a larger pressure surfaces.
What It Changes
It brings a small friction to a precise interval. The window can carry an argument, a sudden minor incident, a travel delay, a snag in the action underway — the self's seat briefly struck, the disturbance immediate and short-lived. At its lightest this is simply a rough couple of hours that passes on its own.
When the hourly clash sits inside a larger clash already pressing on the self, the same window becomes the exact interval on which a heavier matter lands — the longer cycle's weight finding its precise hour.
How To Read It
Read it by what else strikes the same point, and at the proper scale. Standing alone, the hourly clash is buffered and minor — a brief window of friction, useful mainly as information for when not to undertake something delicate. Where the day, month, or year also clash the day master, the hourly clash names the precise interval their force comes due, and the reading scales to the larger cycle.
This is the working tool of 择时 — identifying disadvantageous hours so that delicate undertakings can be set elsewhere. Never flat: a lone hourly clash is a small, passing roughness; one backed by larger clashes is the precise hour a real matter surfaces. The chart's strength and protection still govern the bite.
Where This Shows Up
A window of this kind is felt as brief friction — a short stretch of irritability, a small dispute, a delay, a task that resists. Most such windows are minor and pass with the hour, the ordinary fine-grained roughness of the daily cycle.
The configuration's value is precision: when a heavier cycle already presses on the self, the hourly clash names the exact interval the pressure shows, which is why tradition consults it before timing contracts, journeys, and consequential acts. The texture is immediacy at the smallest scale — a brief disturbance to the self, light on its own and pointed when a larger clash stands behind it.
