December is an English feminine given name taken directly from the name of the twelfth month of the year. As a birth-month name, December may be given to a child born during that month, following a tradition of using month names as personal names.EtymologyThe name December derives from the Latin decem meaning "ten", as it was originally the tenth month of the early Roman calendar, which began in March. When January and February were later added to the beginning of the calendar year, December retained its name despite shifting to the twelfth position.Notable BearersDecember O'Connor, 20th-century American singer and actress
