Saba Saba Day (meaning "Seven Seven" in Swahili, referring to July 7) is a national day of political and economic importance in Tanzania. It originated as the anniversary of the founding of the Tanganyika African National Union (TANU) in 1954, which led the fight for independence from British colonial rule. Over time, it has also become associated with the Dar es Salaam International Trade Fair (DITF), one of the largest trade fairs in East Africa.
