Epiphany is a Christian festival which celebrates the arrival of the Three Wise Men, or Kings, to see the baby Jesus.
Originally, the festival was a pagan celebration of Light. It is in fact at about 6 January that the lengthening of the daylight begins to be noticeable.
On the Feast of the Epiphany, it is traditional in the Grand Duchy to eat a 'galette des rois', a pastry tart filled with frangipane containing a 'bean' token or a figurine and accompanied by a golden cardboard crown.
The person who finds the 'bean' in his or her piece of tart is entitled to wear the crown, and becomes king or queen for the day.
Epiphany (Twelfth Night) is a public holiday in a number of European countries, but not in the Grand Duchy.
