The Greek “Happy Fools’ Day” on April 1st
The Greek “Happy Fools’ Day” on April 1st is traditionally established as the day that we fool the others or tell jokes. On April 1st, you can also use the Greek wish “Καλή Πρωταπριλιά !” (Kali protaprilia) = Happy Fools’ Day! The only difference is that in Greek you actually say “Happy First of April”!
