Is there an Ides of February, or is March the only month with an Ides?

the Romans originally used a Lunar Calendar. The Ides marked the Full Moon, the Kalends marked the New Moon and The Nones marked the first quarter. When the Roman Senate fixed the length of the months, they also fixed the Ides which was fixed as the 15th day of 31 day months and the 13th of the other months the period of the Ides always lasted 8 days (from the Nones to the Ides). The Nones period lasted either 4 or 6 days and the Kalends lasted 16-19 days.

In the Roman calendar, every month had (has) an 'ides', which is roughly in the middle of the month (13th or 15th). Each month opens on the 'kalends', and also has a day known as the 'nones' (5th or 7th of the month).

It's thought they evolved from a prehistoric lunar calendar, with the kalends being the first day of a crescent moon just after the new moon, the nones the first-quarter, and the ides the full moon.

Oddly perhaps to us, the Romans only used these three days when working out the date of a month, counting ahead to the next 'named' date (eg 16th March would be 'the 19th day before the Kalends [of April]...[i]ante diem undevicesimum Kalendas[/i]).

There's an Ides of every month, it was basically the mid point of each month according to the Roman calendar. The Ides of March is only famous because it's the day that Julius Caesar was assassinated

The Ides of March is a literary reference. So, no, nothing for February except "damn, it's cold!"
