Version

Example

Example 81. Find the Julian day count for the infamous "Ides of March"

/*
    "Beware the ides of March.", Act i, Scene 2, Julius Caesar by W. Shakespeare

    Notes:
    The Ides of March occur on the 15th of the month.
    Also, month lengths in the Julian calendar did not stabilize until 8 AD, so
    our Julian day count may be off by a wee bit. :)
