September 30 is celebrated as International Blasphemy Day in some countries. International Blasphemy Day encourages individuals and groups to openly express criticism of religion and blasphemy laws. It was founded in 2009 by the Center for Inquiry.
Blasphemy Day is celebrated on September 30 to coincide with the anniversary of the publication of satirical drawings of Muhammad in one of Denmark’s newspapers, resulting in the Jyllands-Posten Muhammad cartoons controversy.
