Garrett Olmsted of Cornell University argues that Samhain was once observed on the winter solstice (December 21) and gradually shifted to November 1 after centuries of calendar drift.<ref name="Olmsted"/> It is sometimes suggested, especially by neo-pagans, that the Celts intended to select a date halfway between the equinox and the solstice. By this logic, November 7 is the "real" date of Samhain.
