Epiphany - the revelation to the Gentiles, the visit of the Magi, a new insight or understanding, an 'aha' moment... 6th January, or Christmas Day if you are of an Orthodox tradition.
Unless you are hanging on until Candlemas (2nd Feb) then today is the day to pack away your decorations, if you haven't already done so.
Whatever you think about today, I hope that the days ahead bring some smiles and some moments of new or renewed insight.
