In the play "Julius Caesar" by William Shakespeare, Mark Antony eulogizes Caesar in this famous passage:


"Friends, Romans, countrymen, lend me your ears;

"I come to bury Caesar, not to praise him;

"The evil that men do lives after them,

"The good is oft interred with their bones,

"So let it be with Caesar...."


But given the success of the Julian calendar, certainly this good done by Caesar has lived after him.  The Julian calendar was a great step forward for astronomical timekeeping.  It served well for over 1500 years before being adjusted by the Gregorian calendar. And with the Gregorian adjustment, it remains to this day the basis of our modern civil calendar, and also the church calendar that Christians use, such as for celebrating Easter.
