I thought B.C.E. was Before Christian Era. ;)
B.C. means Before Christ. BCE means Before the Common Era. It is the PC way of saying it. BCE is used by academia more and more to avoid any reference to Jesus. The irony is that the beginning of the “Common Era” is tied to the birth of Christ. So whatever you call it, it refers to the birth of Christ.
Nope, Before Chrismas Eve. It became the night before Christmas.
