EVENING LIGHT

Evening light
in Tennessee.

Nashville and Memphis are the comparison cities for Tennessee. Permanent daylight time would move winter sunrise and winter sunset one hour later by the clock. The hour after work keeps the light. The morning trip to school or an early shift gives that hour up. Sunlight itself does not get longer.
