Coincidence. Today for once I noticed that sunrise and sunset was 6:15 and 18:30 respectively and was puzzled. Shouldn’t they be exactly 12 hours apart? After some thought I remembered the definitions of sunrise and sunset. And now I remember a beautiful sunset that I got to enjoy for almost an hour. Above the clouds moving westwards at about the same speed the earth moved eastwards at that latitude.
