It is April 1st and in most parts of the world, friends play pranks on one another, calling them April fools.

The Bible also has some pretty serious references to “Fools” but this is no prank.
An aethesist in Florida, demanded that there be a day honoring aetheism as there is for various other beliefs; Eid for Muslims, Deepavali for Hindus, Hannukah for Jews and Good Friday, Easter and Christmas for Christians. This was an unprecedented request; the first time such as request was brought before the court of law. Without a prima facie, the judge deliberated for a while and then returned with the following verdict.
There will be no particular day set aside for aetheists, because you already have your day. It is April 1st. For all those who do not believe in God are Fools (according to Psalm 14:1 and Psalm 53:1) and there is already a day for Fools.
Court adjourned.

So today while you friends play pranks on you or you on them, remember to use this opportunity to witness to them, that there is a GOD (One and Only) and He is known to us as Jesus Christ.

Psalm 14:1
1. The fool hath said in his heart, There is no God. They are corrupt, they have done abominable works, there is none that doeth good.
