There was also something going on at the Millennium - but they had the date wrong.....

Plus the queen's Golden Jubilee.
And I thought you were old enough to remember her silver jubilee (up to two thousand beacons counting the unofficial ones) in 1977, if not Victoria's jubilee in 1887....

The Royal Institution of Chartered Surveyors are normally involved in organising them so they might be able to give some advice.
