One of the lost customs of the season is the "Chalking of the Door" at Epiphany. The ever reliable Wikipedia tells us:
The three Wise Men, Caspar, Melchior, and Balthazar followed the star of God’s Son who became human two thousand and seventeen years ago. May Christ bless our home and remain with us throughout the new year. Amen.
Of course for the more adventurous there is the Greek custom of the dive for the Cross which is much more challenging in the Northern Hemisphere while our locals get to take advantage of a decent summer dive.
