March 15

Plutarch writes: "A certain seer warned Caesar to be on his guard against a great peril on the day of the month of March which the Romans call the Ides; and when the day had come and Caesar was on his way to the senate-house, he greeted the seer with a jest and said: 'Well, the Ides of March are come," and the seer said to him softly: "Ay, they are come, but they are not gone.'"
