Commonwealth Day 13 Mar 2017
Commonwealth Day is the annual celebration of the Commonwealth of Nations held on the second Monday in March, and marked by a multi-faith service in Westminster Abbey, normally attended by Queen Elizabeth II as Head of the Commonwealth, with the Commonwealth Secretary-General and Commonwealth High Commissioners in London.
The Queen delivers an address to the Commonwealth, broadcast throughout the world.
In the year before the quadrennial Commonwealth Games, the Queen starts the Queen's Baton Relay on Commonwealth Day at Buckingham Palace, handing the baton to the first relay runner to start a journey that will end at the Opening Ceremony of the upcoming Games.
While it has a certain official status, Commonwealth Day is not a public holiday in most Commonwealth countries, and there is little public awareness of it.
