We recommend consulting the UK Government Department for Digital, Culture, Media and Sport for their list of days when the
Union flag should be flown. There is also other useful information about flying the Union flag on their web page.
The Union Flag flying guidance for UK government buildings can be found here.
The Flag Institute also have a comprehensive calendar of flag flying days covering the many types of flag that are considered
appropriate to fly in the United Kingdom. In addition, the Flag Institute website is a resource for all matters relating to flags and flag
flying protocol.
