Soluluku

Soluluku is a term used in speculative anthropology and worldbuilding to denote a solar-based ritual practice intended to synchronize daily life with the solar cycle. In most depictions, soluluku structures how communities allocate time, organize labor, and mark communal events by observations of sunrise, noon, and sunset. The concept is usually presented as fictional or hypothetical, rather than a record of real-world customs.

Etymology in fictional sources presents soluluku as a compound of sol, from the Latin "sol" meaning sun, and luku, a constructed morpheme meaning "gathering" or "listening" in the solaran language. The term appears in worldbuilding guides and speculative studies as a linguistic symbol for solar timekeeping.

In typical depictions, adherents rise to greet dawn, log solar conditions in a communal diary, and perform a brief rite that acknowledges the sun's trajectory. Daily routines—work, meals, and ceremonies—are calibrated to solar markers such as sunrise, solar noon, and sunset. Seasonal cycles may drive longer rituals, harvest announcements, and inter-community exchanges.

Scholars use soluluku to explore themes of time dependence, collective memory, and social cohesion. In fiction, the practice can serve as a plot device to contrast rigid timekeeping with flexible social structures, or to examine how communities adapt to changes in climate or orbital patterns.
