The story is not true
Christians do not even celebrate april fool's day the real story is as
following:
The origin of April Fools' Day is obscure. One likely theory is that the modern
holiday was first celebrated soon after the adoption of the Gregorian Calendar;
the term referred to someone still adhering to the Julian Calendar, which it
replaced.[2] In many pre-Christian cultures May Day (May 1) was celebrated as
the first day of summer, and signaled the start of the spring planting season.
An April Fool was someone who did this prematurely. Another origin is that April
1 was counted the first day of the year in France. When King Charles IX changed
that to January 1, some people stayed with April 1. Those who did were called
"April Fools" and were taunted by their neighbors. citation needed] In the
eighteenth century the festival was often posited as going back to the times of
Noah. An English newspaper article published on April 13th, 1789 said that the
day had its origins when he sent the raven off too early, before the waters had
receded. He did this on the first day of the Hebrew month that corresponds with
April.[3] A possible reference to April Fools' Day can be seen in the Canterbury
Tales (ca 1400) in the Nun's Priest's tale, a tale of two fools: Chanticleer and
the fox, which took place on March 32nd.[4]
