A [[Game-day|day]] lasts 25000 [[Game-tick]]s or 416.66~ [[Game-second]]s.
 
The light varies throughout the day in a cycle consisting of 4 phases:
{| class="wikitable"
! 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~

|}

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 [https://lua-api.factorio.com/latest/LuaSurface.html#LuaSurface.darkness LuaSurface.darkness]. During night time, [[player]]s will passively activate their flashlights (or headlights if in a [[vehicle]]), and placed [[lamp]]s will turn on automatically if powered.
 
Note: The actual time between phases can vary +/- a tick due to rounding errors.
