What January means

Where January comes from and what it has meant to the people who carry it.

January comes from the Latin Ianuarius, the name Rome gave its first month, and that word grew from Janus, the god of doorways, gates, and beginnings. The short meaning follows plainly: belonging to Janus. The god was shown with two faces. One looked back at the year that had ended, the other ahead at the year opening.

As a given name, January belongs mostly to the English-speaking world, where it stays uncommon and stands alone, with no settled diminutives or variants. Its best-known bearer is the American actress January Jones, from the series Mad Men. Her parents took the name from January Wayne, a character in Jacqueline Susann's 1973 novel Once Is Not Enough.

So the name reaches modern ears through a Roman deity by way of a bestselling paperback. It stays close to its root all the same. To carry January is to carry Ianuarius, belonging to Janus, the two-faced keeper of the threshold.
