Double hour 6 of 12 · 時支
The Snake hour
巳 Si holds 09:00–10:59 on the modern civil clock. Tradition fitted the snake to it as the hour snakes leave their burrows without troubling anyone.
One branch · four linked coordinates
What stays fixed in the Snake period
The clock selects one Earthly Branch. The same branch also carries a phase, compass direction and solar-term month; those links are structural coordinates, not extra personality labels.

Five complete Snake hour pillars are possible
The branch is fixed by the clock. The stem advances from the Day Master, so the ten day stems fall into five rule pairs and produce five possible hour pillars here.

Two clock edges
The Snake hour changes at 09:00 and after 10:59
A time earlier than 09:00 belongs to the preceding branch; a time after 10:59 belongs to the next. This site reads the local civil time entered and does not silently apply longitude, daylight-saving or apparent-solar-time corrections.
Known time
A recorded local time selects this branch and allows the hour stem to be derived from the day stem.
Unknown time
The hour pillar stays absent. Assuming noon or another default would invent two of the chart’s eight characters.
The same branch geometry at every scale
Its clash, harmony and trine do not change with the clock
The Snake branch clashes with Pig, forms Six Harmony with Monkey, and belongs to the Metal trine with Snake and Rooster and Ox. These relationships come from fixed positions.
