Aprilis

Aprilis or mensis Aprilis (April) was the fourth month of the ancient Roman calendar, following Martius (March) and preceding Maius (May). On the oldest Roman calendar that had begun with March, Aprilis was the second of ten months in the year. April had 30 days on calendars of the Roman Republic, with a day added to the month during the reform in the mid-40s BC that produced the Julian calendar. April was marked by a series of festivals devoted to aspects of rural life, since it was a busy month for farmers. As Rome became more urbanized, the significance of some ceremonies expanded, notably the Parilia, an archaic pastoral festival celebrated as the "birthday" (dies natalis) or founding day of Rome. The month was generally preoccupied with deities who were female or ambiguous in gender, opening with the Feast of Venus on the Kalends.
