"January was named after Janus, a sky-god who was ancient even at the time of Rome's founding. Ovid quoted Janus as saying "The ancients called me chaos, for a being from of old am I." After describing the world's creation, he again quoted Janus: "It was then that I, till that time a mere ball, a shapeless lump, assumed the face and members of a god." A Lydian named Joannes identified Janus as a planet when he wrote: "Our own Philadelphia still preserves a trace of the ancient belief. On the first day of the month there goes in procession no less a personage than Janus himself, dressed up in a two-faced mask, and people call him Saturnus, identifying him with Kronos."
Early Romans believed that the beginning of each day, month and year were sacred to Janus. They thought he opened the gates of heaven at dawn to let out the morning, and that he closed them at dusk. This eventually led to his worship as the god of all doors, gates, and entrances.
Some say Februarius got its name from a goatskin thong called a februa ("means of purification.") On the 15th day of this month Romans observed the festival of Lupercalia. During the festival, a februa was wielded by priests who used it to beat women in the belief that it would make a barren woman fertile. However, there's a Latin verb februare, meaning to "expiate" or "purify." It seems more reasonable to assume the purification people had in mind when naming the month was that of the calendar year's length, not that of women upon whom the thong was applied."
February also devoted to the Infernal Gods.
