Life on Anesidore is split into Day and Night, each lasting for twelve hours. Day is when Talon is visible as Sun, and Night is when Talon is visible as Moon. You orient your Work around the cycles both of Day and Night, and the [[trin]]-day cycle of traversal from systole to diastole of each Orbit (the length of one half-Orbit): [[vigour]] days' accommodation given for traversing and completing the Work required in one half of an Orbit, and [[three]] days' accommodation given at both the [[Red Garden]] at the Orbit systole and the [[Remembry]] at the Orbit diastole.
