Q: I will not be home on the 6th Jan, so what do I do? I was actually told that 12 night is on the 5th Jan.
A: You should take down your decorations any time between sunset on the 5th January, and Sunset on 6th January - which is the period of twelfth night. The bad luck is leaving them up longer. If you forget you are supposed to leave them up all year, or not take them down until easter. Leave one small decoration in place all year.
