March 15th, esoterically speaking.
At dawn of the year 44 BC, however, on this day, Calpurnia woke up in tears. She had had a dream that her husband had been stabbed and was dying in her arms.
Calpurnia told her husband about this dream, and still sobbing pleaded with him to remain at home, for outside only his grave awaited.
Julius Caesar pushed her aside and walked toward the Roman Senate, to his death.
