In the United Kingdom, there are designated days each year when the Union Flag must be flown on UK government buildings. These dates mark significant royal, national, and commemorative occasions — and they're a wonderful reminder of the rich tradition of flag flying across the country.

UK government buildings are also encouraged to fly the Union Flag all year round, not just on designated days.

Flying the Union Flag Correctly

On designated days, the Union Flag should be flown from sunrise to sunset (or, where lighting permits, after dark). It must always be flown the right way up — the broader diagonal white stripe should be uppermost on the side nearest the flagpole.
