Important UK flag flying days for your diary

Flying the Union Flag is a great way for businesses, organisations, and public buildings to show respect, pride, and awareness of key national events. In the UK, there are a number of officially recognised days each year when the Union Flag is traditionally flown.

Whether you already have a flagpole or are thinking about installing one, knowing these dates helps you get the most from it.

Key UK union flag flying dates

Some of the most important dates in the calendar include:

• Commonwealth Day – Celebrates the unity of the Commonwealth nations

• King’s Accession Day (6 February) – Marks the anniversary of the King’s accession to the throne

• King’s Birthday – Officially celebrated on the third Saturday in June

The Union Flag may also be flown during national celebrations, royal events, and other significant occasions.

Why flying the union flag matters

Displaying the Union Flag on these dates shows respect for tradition and helps businesses and organisations connect with the wider community. For commercial premises, flagpoles at the entrance create a strong visual impact, helping buildings stand out while projecting professionalism and pride.

Make the most of your flagpole

A well-positioned flagpole allows you to mark these important dates throughout the year and keeps your site looking active and engaged. Many businesses choose to fly the Union Flag on designated days and swap to branded or promotional flags at other times.
