Called Oonar in Coraabish language.
A Light Day is a unit of time used on Coraab. It consists of 96 Uns and is therefore longer than a Haze Day by one third. Together, these two days form the so-called Tol.
Its name is derived from the light reigning on that Coraabian hemisphere currently oriented towards Unaar during Oonar. The sunlight is accompanied by insufferable heat waves which may occur in this period. The Light Day is one big rush hour in Coraabian civilisation.
These units of time were used on Coraab since times immemorial although their author isn't known anymore. The first recorded usage of a two-day cycle is dated to a period around -12,000 Tu.
Tol - 1 Period of Excavation | has 2 days
Pozn.:The duration of Light Day is equal to our 4 days.
