yes they were. Christmas used to be Saturnalia, an old Roman holiday about the rebirth of the SUN, hence the date falling on or near the winter solstice. A couple things got changed around and BAM, the Roman Empire assimilates Christianity.
Ditto goes to Easter. I forget the roots but it has something to do with the coming of Spring and some sort of Fertility Goddess; Eggs and Rabbits being symbols of being fertile (and making babies). I forget how they changed it, but I imagine it not being too hard, since it was originally about the earth "coming to life again."
