National Gibberish Day

National Gibberish Day is an unusual American holiday dedicated to gibberish. It is celebrated annually on September 20th in some US states.


The origin of this holiday is unknown. Gibberish in modern language means speech that does not make sense to most people, or not at all. It may consist of speech sounds that are not real words. This concept also includes professional jargon, which the vast majority of people will not know.

National Gibberish Day is usually celebrated by representatives of certain professions or any other group of people who have their own ‘language’.

Researchers studying the formation and development of various languages ​​express the opinion that the appearance of incomprehensible or slang speech can be attributed to Jabir ibn Hayyan. And the term ‘gibberish’ itself came from his name. He lived in the 8th century and was an alchemist. Records of his research were kept in a coded language that only those close to him could understand. Samuel Johnson, the creator of The English Dictionary, explained the emergence of gibberish as a linguistic phenomenon in this way. In the future, many researchers questioned his theory, although no one could offer a more realistic replacement for it.
