Skejby Sunset

My last skejby sunset, unfortunately not viewed from my former apartment.
Is sunset part of day or part of night? This enigma is compounded by the fact that the sun in Denmark sets at about 10.30pm now. Enigma. Can it be night if there is still bright sunlight.
An enigma and a large serving irony has been the day's menu for the past few days.
I am tired but I have so many things to do and so many people to please.
