World Post Day is observed every year on October 9 to mark the establishment of the Universal Postal Union (UPU) and the creation of the revolutionary mode of communication with letters in the everyday lives of the people. Before the age of e-mails, letters used to be handwritten and delivered by post across the world. Even today, postal services hold a significant role in the delivery of parcels globally.
World Post Day is celebrated in remembrance of the foundation of the Universal Postal Union (UPU) in 1874 in Bern, Switzerland. Celebrated across 151 countries, it was first declared as the World Post Day by the UPU Congress held in Tokyo, Japan, in 1969. In India, too, the day acknowledges the beginning of National Postal week, celebrated from October 9 to October 15.
