Dear Robert, Sunrise is defined as the moment the top of the sun's disc first breaks the plane of the horizon in the morning, and sunset is when the top of the sun's disc sinks below the horizon in the evening.
Sunrise & sunset are unique to a specific place and the particular day. This diagram from the Wikipedia page on Sunrise is fascinating in showing the actual position of the sun when we see sunrise and sunset. I had never appreciated just how far below the horizon the sun actually is when it sets.
