Most of our major divisions of time are based on some sort of natural event.  A year is one orbit of the Earth around the sun. A month is one orbit of the Moon around the Earth. A day is one rotation of the Earth about its axis.  However, one of the most commonly used units of time has no natural analog whatsoever.
