Have you been fooled today? Did you feel embarrassed?
...Well you should be aware with April Fools Day
April Fools' Day or All Fools' Day, although not a holiday in its own right, is a notable day celebrated in many countries on April 1. The day is marked by the commission of hoaxes and other practical jokes of varying sophistication on friends, family members, enemies, and neighbours, or sending them on fool's errand, the aim of which is to embarrass the gullible.
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.
