World Post Day is celebrated each year on 9 October, the anniversary of the establishment of the Universal Postal Union in 1874 in the Swiss Capital, Bern. It was declared World Post Day by the UPU Congress held in Tokyo, Japan in 1969. Since then, countries across the world participate annually in the celebrations. The Posts in many countries use the event to introduce or promote new postal products and services.
In 2015 countries all over the world committed themselves to working together towards achieving the Sustainable Development Goals, which aim to end extreme poverty and hunger, fight inequality and injustice, and take action to reverse climate change--to name just some of these 17 agreed new Goals. Playing its part in this global effort, the Post today has a more relevant role than ever by providing infrastructure for development.
