For most people "the holiday season" is over. For us, it's just getting started!
Twelfth Night is the night twelve days after Christmas. It's the day that tradition says the three wise men visited the newborn baby Jesus. It's the feast of the Epiphany. Many people celebrate this by exchanging gifts, much like Christmas.
This is the first night of Carnival! Carnival lasts from Twelfth Night to Fat Tuesday (the Tues before Ash Wednesday). Fat Tuesday is Feb 28th this year. I for one, cannot wait. Mardi Gras is my favorite holiday. :-)
