The Queen's Official Birthday is a common public holiday in the Commonwealth realms and British overseas territories. It is typically observed in June. For example, New Zealand and its associated states, the Cook Island and Niue, celebrate the official birthday of the Queen on the first Monday in June.
In 2010, the United Nations launched the initiative of the UN Languages Day to promote the UN's official working languages, multilingualism and cultural diversity. UN Russian Language Day is celebrated on June 6.
