April 23 is rich with historical significance across literature, science, and world events. Most notably, it’s celebrated as Shakespeare Day, believed to be both the birth and death date (1564–1616) of William Shakespeare, the legendary English playwright and poet. The day is also recognized as World Book Day by UNESCO, honoring literary heritage and reading worldwide.
In 1968, UNESCO was founded, and in 2005, April 23 was declared World Book and Copyright Day in recognition of several prominent authors who died on this day, including Shakespeare and Miguel de Cervantes, who died in 1616 as well (though due to calendar differences, not the exact same day).
Additionally, in 1985, Coca-Cola introduced “New Coke”, a marketing move that famously backfired, making it one of the most well-known product flops in U.S. history.
