Saba Saba Day on July 7 celebrates (among other things) the 1954 founding of the Tanzanian political party, TANU, the Tanganyika African National Union. Saba Saba means "seven seven" in Swahili, the national language of Tanzania (and of Tanganyika and Zanzibar, the two countries whose union created the United Republic of Tanzania in 1964). Saba Saba also may refer to the Dar es Salaam International Trade Fair. The fair is held every year on this date in Saba Saba grounds near Kurasini in Dar es Salaam.
Saba Saba is also the day protesters in Kenya demanded successfully free elections in 1990.
