A referendum is begun in Bosnia and Herzegovina for the determination of Bosnian independence.

The Socialist Republic of Bosnia and Herzegovina, commonly referred to as Socialist Bosnia or simply Bosnia, was one of the six constituent federal states forming the Socialist Federal Republic of Yugoslavia. It was a predecessor of the modern-day Bosnia and Herzegovina, existing between 1945 and 1992, under a number of different formal names, including Democratic Bosnia and Herzegovina (1943–1946) and People's Republic of Bosnia and Herzegovina (1946–1963).

An independence referendum was held in the Socialist Republic of Bosnia and Herzegovina between 29 February and 1 March 1992, following the first free elections of 1990 and the rise of ethnic tensions that eventually led to the breakup of Yugoslavia. Independence was strongly favoured by Muslim and Bosnian Croat voters while Bosnian Serbs boycotted the referendum or were prevented from participating by Bosnian Serb authorities.

February 29 is a leap day —an intercalary date added periodically to create leap years in the Julian and Gregorian calendars. It is the 60th day of a leap year in both Julian and Gregorian calendars, and 306 days remain until the end of the leap year. It is the last day of February in leap years only. It is also the last day of meteorological winter in the Northern Hemisphere and the last day of meteorological summer in the Southern Hemisphere in leap years.
