Game-day

A day lasts 25000 Game-ticks or 416.66~ Game-seconds.

The light varies throughout the day in a cycle consisting of 4 phases:

Phase Name	Internal name	Behaviour	Time of day at start	Time of day at end	Duration (in ticks)	Duration (in seconds)
day	dawn	fully light	0.75	0.25	12500	208.33~
sunset	dusk	darkening	0.25	0.45	5000	83.33~
night	evening	fully dark	0.45	0.55	2500	41.66~
sunrise	morning	lightening	0.55	0.75	5000	83.33~

During sunset, the light level decreases linearly from fully light to fully dark. During sunrise, it increases linearly from dark to light. This linear slope does not necessarily apply to the values returned by LuaSurface.darkness.

Note: The actual time between phases can vary +/- a tick due to rounding errors.
