Epiphany

The word for today is Epiphany I always thought Epiphany referred to the season directly after Christmas - and it is called Epiphany for a reason.  The definition of Epiphany is a sudden perception of an essential truth.   A grasp of reality in a sudden and startling way.  It's sort of like with the light bulb in your head goes off and you suddenly understand what something is or why something is the way it is.  "My epiphany came suddenly when he said he wanted a divorce."
