December's name derives from the Latin word decem (meaning 10) because it was originally the 10th month of the year in the calendar of Romulus , which began in March. The winter days following December were not included as part of any month. Later, the months of January and February were created out of the monthless period and added to the beginning of the calendar, but December retained its name.
