Rialto gets 4h 31m more daylight on the longest day than the shortest. Sunset moves from 4:41 PM in December to 8:02 PM in June, so an evening shoot that works in summer will be shooting in the dark at the same clock time in winter.
Blue hour follows sunset and is worth planning for separately: in June it runs until about 8:31 PM, and in December until about 5:09 PM.
Golden hour is the period near sunrise and sunset when the sun is low. Blue hour occurs before sunrise and after sunset. Calculated times vary with location and date; weather, terrain and buildings can affect visible light.
