Rwanda, a new member of the Commonwealth, this year, joined other members to celebrate the Commonwealth Day.
Commonwealth Day (formerly Empire Day) is the annual celebration of the Commonwealth of Nations, since 1977 often held on the second Monday in March. It is marked by an Anglican service in Westminster Abbey, normally attended by Queen Elizabeth II as Head of the Commonwealth along with the Commonwealth Secretary-General and Commonwealth High Commissioners in London. The Queen delivers a broadcast address to the Commonwealth.
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. It is marked as a holiday in Gibraltar, but not in March.
