September 21 is special for being designated as the International Day of Peace, also known as World Peace Day. It is a United Nations-sanctioned holiday dedicated to promoting peace among all nations and peoples, encouraging global ceasefire and non-violence for a 24-hour period. The day was established in 1981 and officially observed annually on September 21 since 2002. It serves as a reminder to strengthen the ideals of peace and reflects hope for a more peaceful world.
Additionally, September 21 is recognized as Escapology Day, celebrating the art of escape, and various other observances such as National Chai Day and Wife Appreciation Day in some countries.
Historically, important events also occurred on this date, including the release of J.R.R. Tolkien's "The Hobbit" in 1937, which had significant literary impact. Notably, it is also associated with cultural heritage and peacebuilding practices around the world.
In popular culture, this date is famously referenced in Earth, Wind & Fire's song "September" with the line "Do you remember the 21st night of September".
