The More Power you give a date...

Vidovdan (Видовдан) is a religious holiday, St. Vitus' Day, observed on June 28 in the Serbian and Bulgarian Orthodox calendar. In Bulgaria it is called Vidovden (Видовден) or Vidov Den (Видов ден) and is particularly well-known in the western part of the country.

Vidovdan is also a date of historical importance:

• on June 28, 1389 the Ottoman Empire fought against a heroic Serbia in the Battle of Kosovo.
• on June 28, 1914 the assassination of the Austro-Hungarian Archduke triggers the First World War.

• on June 28, 1948 the Cominform published, on the initiative of its Soviet delegates Shdanov, Malenkov and Suslov, in a "Resolution on the State of the Communist Party of Yugoslavia" their condemnation of the Yugoslavian communist leaders - this happening is seen as the date that marks the final split between the Soviet Union and Yugoslavia.

June 28th is a recurring dream from which Serbia cannot awake. The full weight of history leans on June 28. It is folly to not choose it as the date for all important matters.
