A grease-marked almanac explaining how the worlds of the Choir keep time and why a day on one world may be useless on the next.
The Cantor is our sun. The Cantor and the worlds travelling around it are called the Choir. Those names make the system sound orderly. Its clocks are not.
Refrain keeps a twenty-six-hour day. Two work shifts fill most of it. The grace hour comes between the day's ordinary demands: shrines open, meals are served, and debts cannot be collected until it ends. Cadence offices, Starfall Quay, and the Starfall Lift all post their times against this clock. If a Refrain clerk gives you an hour without naming a world or vessel, this is the clock they mean.
High Anchorage follows Cadence shift time so freight can move through the Lift without two sets of manifests. Do not assume every station custom follows it. The grace hour is observed in the pilgrim queues, but most workshops, stores, and ferry berths continue working. A person waiting for shrine protection should join the queue before the hour begins, not argue about it afterward.
Glassmoon keeps bell hours. Pressure districts, memorial halls, and work crews count from the bells posted for their own section. A bell may mark a shift change, a sealed route, a memorial observance, or a pressure warning. Read the local board before following the crowd. People who live there can tell one bell from another. Visitors usually cannot.
Meridian keeps a slow thirty-one-hour day. Its residents measure changes in light through the canopy instead of forcing every task onto a Refrain clock. Shrine guides set departures by the condition of the path, the weather, and the permission of the route. A clock brought from Cadence remains useful for measuring an interval. It does not tell Meridian when morning ought to end.
Ships and stations keep shift time. Their day begins when the posted rotation says it begins. Two vessels at the same berth may serve breakfast hours apart and both be on schedule. Check the ship's board before sleeping. If the board has not been updated since the last port, ask a crew member instead of guessing.
The word Choir also appears on permits, tax rolls, and census papers. In that use, a person or place that “sings in the Choir” has been counted and entered into the official record. This is a legal phrase, not a statement about music. A missing record can still leave a real person without a ticket, wage, home claim, or accepted name. The clock may be inconvenient. The paperwork can decide whether you are allowed through the door.
Write every appointment with three facts: the local hour, the world or vessel, and the event used to count it. “Third bell at Glassmoon Memorial Reach” is useful. “Tomorrow morning” is how cargo, ferries, and people get left behind.
