Meridian clock: the two-hour cycle

Study cycle

The clock divides the day into twelve two-hour bands, one for each primary meridian. It is a classical memory map. It does not say when to act on anyone.

What it is for in class

The cycle helps you remember channel order: metal, earth, fire, water, ministerial fire, wood. Each band links to the meridian sheet. Studying the hour does not replace locating the point on the body.

What this table is not

It is not a treatment timetable, nor advice to activate an organ at that hour. When a school uses it, it is an ordering poem beside the atlas.

Classical study cycle, from 03–05 to 01–03. Each name opens the meridian.

Questions

Which time zone are the hours in?
The classical study table is memorized in two-hour blocks, as manuals pass it on. It is not adjusted to a country or a wristwatch for making decisions.
Why does it start with Lung at 3?
Because the traditional teaching cycle opens with Lung (03–05) and closes with Liver (01–03). That is the order linked to the sheets.

Study reference within traditional Shiatsu/TCM frameworks. Does not diagnose or treat.
