Why does not the Earth experience 12 hours of daytime and 12 hours of night time everyday?
Explanation: Rotation of the Earth causes night and day to alternate.

Why does Earth receive 12 hours of sunshine during equinox?
Neither of the poles are tilted towards the sun. Hence, the sun rays fall directly on the equator due to which all the places on the Earth experience equal daylight hours and equal night time hours that is, 12 hours of day and 12 hours of night on all the places of the Earth.
