Trooping of The Queen’s Colours is an extremely traditional ceremony that has taken place by different British regiments since the 16th century and since 1748 has been planned to mark the sovereign’s official birthday. Within the United Kingdom the ceremony is celebrated on a Saturday in June. This year (2013) it will be held on the 15th.
