<P> A Diamond Jubilee Lecture was delivered in March, a flower show and tea party was held at Government House on 4 and 5 May, a stamp exhibition was mounted at the National Trust headquarters and an exhibition of photographs of the Queen in Saint Vincent and the Grenadines was displayed at the National Public Library . A Queen's Birthday parade took place, as did a Diamond Jubilee Beacon Event on 4 June, part of the wider plan to light such beacons at the same time across the Commonwealth . </P> <P> In the United Kingdom, national and regional events to mark the Diamond Jubilee were coordinated by the Queen - in - Council and her Royal Household at Buckingham Palace . As with the Golden Jubilee in 2002, the Department for Culture, Media and Sport was responsible for coordinating the Cabinet - led aspects of the celebrations . Events were planned so as to keep the use of tax money to a minimum; most funds used to fund celebrations were drawn from private donors and sponsors . Only the cost of security was by Her Majesty's Treasury . The British logo for the Diamond Jubilee was selected through a contest held by the BBC children's programme Blue Peter; the winning design, announced in February 2011, was created by ten - year - old Katherine Dewar . Drupal, a free open - source content management system, was used for the official website . </P> <P> On 5 January 2010, the Lord President of the Council and Business Secretary Lord Mandelson announced that an extra bank holiday would take place on 5 June 2012 . Moving the Spring Bank Holiday (the last Monday in May) to 4 June resulted in a four - day holiday in honour of the Diamond Jubilee . As national holidays are a devolved matter, Scotland's first minister confirmed that the bank holiday would be held on 5 June in Scotland . Some economists later theorised that the holiday could reduce the country's gross domestic product by 0.5% in the second quarter of the year, though this would be partially offset by increased sales for the hospitality and merchandise sectors . </P> <P> Many events were staged in London during the bank holiday weekend . The River Thames Diamond Jubilee Pageant was held on 3 June . The Diamond Jubilee Concert, with a preceding afternoon picnic in the palace gardens for the 10,000 concert ticket holders, was held the following day, in front of Buckingham Palace, and featured acts representing each decade of the Queen's 60 - year reign . </P>
