An insightful article on Biblical Archaeology about the dating of Christmas and other Christian holidays. Some argue that Jesus was conceived on April 6, born on January 6, and crucified on April 6. Cyclical views of time where significant events fall on certain, specific, special days (perhaps borrowing from Judaism) may be more informative to the development of these dating traditions rather than linear notions of time, which are quite western.
I rather like the idea of celebrating the real 12 days of Christmas, starting on December 25 and ending on January 6. What is there not to like about 12 days of holidays?
