Believe it or not, this holiday has it's roots in Anti-Semitism.

For thousands of years, mankind has known that the year actually began in Spring.  God's 1st day of the year always falls sometime in late March or April.  But, according to the "new" Gregorian calendar, established in 1562, the first day of the new year now fell in January in the dead of winter.... 

The Hebrew Calendar was the tried and true calendar for Christians, but, it became considered foolish to go by it.  And if you obeyed God and His system and went by His calendar, you were called a fool by those who didn't.

Even though, early on, the whole world had at one time understood that the first day of the year always fell around the time of April.  (*Although, it must be mentioned that they lost the exactness of it...and knew it in generality only.)

An article on April Fools Day explains.

"In sixteenth-century France, the start of the new year was observed on April first and was celebrated with parties and dancing into the late hours of the night. Then, in 1562, Pope Gregory introduced a new calendar for the Christian world and the new year fell on January first...." 

It was at this time that April Fools Day was invented to poke fun at God's people for being so foolish as to try to stick with the Hebrew Calendar.  Ever after that, anyone who kept Gods more proper calendar was made fun of and laughed at.  They were called "April fools."   I like the term January Fools better.
