Independence and Unity Day is a national holiday in Slovenia that is celebrated annually on December 26th. The holiday marks a significant historical milestone for Slovenia, commemorating the official proclamation of the results of the independence referendum held on December 23, 1990. On this momentous day, an overwhelming majority of Slovenians voted for independence, paving the way for Slovenia to become a sovereign nation.

Upon its establishment, the Republic of Slovenia declared its independence from Yugoslavia on June 25, 1991. However, the independence and unity referendum results aren't officially announced until December 26, thus, giving birth to the holiday. The holiday is not just a celebration of independence, but also of the unity and determination that led Slovenian citizens to overwhelmingly choose independence.

Typically observed with an array of public and private festivities, Slovenia's Independence and Unity Day is marked by multiple celebratory events across the country. Some of these activities involve cultural and sporting events, formal ceremonies, and covert concerts. As with any national holiday, governmental institutions, businesses, and schools are typically closed to allow Slovenians of all ages to reflect and celebrate their national identity.
