English is one of the most widely spoken languages in the world and is spoken by two billion people today. In fact, "English" accepts at least 100 languages from the region, adopting the Roman alphabet, absorbing Danish, and borrowing characters from French and Latin. It was not until the end of the nineteenth century that English became a world language.

World English Day is one of the six official languages adopted by the United Nations in 2010. Official languages were established to encourage linguistic and cultural diversity and to emphasize the importance of communication.

English Day was established on April 23rd, the birthday and anniversary of Shakespeare's death. Shakespeare was a distinguished dramatist, actor, and one of the distinguished writers of Western literature. Shakespeare broadened his new English vocabulary with his work. It spread widely, and the transmission of Middle English enriched the modern English. Many of the English used today have been added to the English lexicon after his first use, and have developed an indelible contribution.
