Many people today do not realize that the names we use for the months of the year and the days of the week have sacred origins, celebrating the gods and goddesses worshipped by our early ancestors. For example, January, the first month of the year, was called Januarius by the Romans, after Janus, the god of doors and gates, while Tuesday, the third day of the week, was named after Tiu, the Anglo-Saxon God of War. In Pagan Origins of the Calendar: Stories of the Months and Days, Reginald Couzens shares the legends of the goddesses and gods hidden in our calendar.
