When is Zanzibar Revolution Day?
In 2026, Zanzibar Revolution Day falls on Monday, January 12, 2026. It is classified here as a paid public holiday.
History of Zanzibar Revolution Day
Zanzibar Revolution Day marks January 12, 1964, when an uprising overthrew Sultan Jamshid bin Abdullah and the ZNP–ZPPP government barely a month after independence from Britain. The Afro-Shirazi Party became the dominant political force and Abeid Amani Karume headed the revolutionary government. Official memory emphasises the end of racialised privilege and later changes in land, housing, education and health; those claims belong in the record without turning a contested revolution into a simple morality tale.
The overthrow and aftermath included killings, detention, dispossession and forced or fearful emigration, especially among Arab- and South Asian-identified residents and perceived government supporters; scholarly death estimates vary substantially. Racial categories in Zanzibar had themselves been shaped by slavery, Omani and British rule, migration, class and electoral politics and were not timeless biological blocs. The holiday is statutory across the United Republic, but its central history, memory and ceremonies are distinctly Zanzibari.
The Public Holidays Act, Cap. 35 R.E. 2023, places this holiday in the Union schedule and permits the President to add or substitute dates by proclamation. Unlike older editions still reproduced online, the current Act contains no automatic Saturday-or-Sunday replacement section; its 2026 calendar therefore supplies no Monday substitute for a weekend date. A department head may require public servants to work. On the mainland section 26 of the Employment and Labour Relations Act requires double basic-wage pay for holiday hours worked; Zanzibar employment is separately governed by section 67 of its 2005 Act, which provides a full-pay holiday or the specified compensatory-day/double-pay treatment.
