"July was renamed for Julius Caesar, who was born in that month. Previously, it was called Quintilis in Latin, since it was the fifth month in the ancient Roman calendar, before January became the first month of the calendar year (the year when displayed as twelve months in order) during the time of the decemvirs about 450 BC. In the ancient Roman calendar the ides of July fell on the 15th day of the month."
