The Coronation Anniversary of Vytautas the Great is observed in Lithuania every September 8. This unofficial observance commemorates Vytautas, a national hero and one of the most notable rulers of the Grand Duchy of Lithuania, who is revered despite never having been officially crowned. The significance of this date stems from the planned coronation on September 8, 1430, which ultimately did not occur due to delays at the Polish-Lithuanian border, and Vytautas's subsequent death shortly thereafter. The day serves as a reminder of his contributions to the centralization and economic development of Lithuania. Although it is not an official holiday, Lithuanians honor Vytautas's legacy and his role in the Lithuanian National Revival.
