One of the best ways to get a feel for Zanzibar beyond the beach is to time a visit around one of its festivals — from a centuries-old New Year ritual to a modern international film festival. Here are the ones worth knowing about.

Sauti za Busara — Music and Culture in February
Sauti za Busara ("Sounds of Wisdom" in Swahili) is an annual music and cultural festival founded by Busara Promotions in 2003, with its first edition held in Stone Town in February 2004. It has grown into one of East Africa's best-known music events, over a long weekend of concerts, theatre and dance across the Old Fort (Ngome Kongwe) and other venues around Stone Town, opening with a street parade through the old town on day one.

Mwaka Kogwa — A Persian-Rooted New Year in Makunduchi
Every year around 23–24 July, the southern village of Makunduchi holds Mwaka Kogwa, a four-day celebration widely said to descend from Nowruz, the Persian New Year, brought to the coast by early Shirazi settlers. Men mock-fight with banana stems to work off the year's frustrations, women parade through the village in their best clothes singing about family, and a traditional healer lights a fire and reads the smoke as a sign for the year ahead. It closes with a shared feast.

Zanzibar International Film Festival (ZIFF) — July
Known as the Festival of the Dhow Countries, ZIFF runs for two weeks each July, screening films from Africa, the Gulf States, Iran, India, Pakistan and the wider Indian Ocean region alongside music, theatre, dance and workshops, much of it centred on Forodhani Gardens in Stone Town. Competition entries compete for the Golden and Silver Dhow awards.

Eid El-Fitr — the End of Ramadan
Eid El-Fitr marks the end of Ramadan, the month of fasting and reflection observed across Zanzibar. Ramadan and Eid dates shift by about 11 days each year on the Islamic calendar; during Ramadan some restaurants adjust their hours and food can be harder to find outside the main towns during daylight. When Eid arrives, the island celebrates for about four days — new clothes, family visits, Taarab music and dancing well into the night.
If your stay lines up with one of these, it's worth building a day around it — your butler can help with timing and getting there.
