The name February is a girl's name of English, Latin origin meaning "purification feast". February and is often added to lists like Middle Names for Girls and discussed in our forums with posts like "Alphabetical This or That".
From the experts:
If January, April and August are useable and fashionable, why not February? February as a word derives from the Latin februa, which was the name of a purification feast which, coming at the end of winter, would prepare one for the coming spring. For our part, we like February along with December and January as names for winter babies; we also like the possibility of Airy and Rue as nicknames. A possible stumbling block, however, is that clumsy "bruary" sound in the middle that no one ever quite gets right.
