Why was the ides of march called the ides of march

The ides of March was called the ides of March because that was what it was. The ancient Roman calendar did not follow the same dating system as our present day calendar. The months were divided into three lunar sections which were the Kalends, Nones and Ides. Every month had all three divisions. In the case of the ides, it could fall on either the 13th or the 15th of the month. In March the ides were on the 15th.
