April Foolishness 2005: "April Foolishness 2005
No one knows exactly how or when April Fools' Day originated, but it probably had something to do with the adoption of the Gregorian calendar in the mid-17th century, which resulted in the observance of New Year's Day being switched from the last week in March to the first of January.

Legend has it (i.e., for all we know, it's completely false) that the original 'April fools' were those clueless few who, ignorant of the calendrical change, continued to ring in the new year on the eve of April first. In any case, ever since ancient times the advent of spring has been marked with lighthearted revelry and pranksterism."
