Cuba Time (Havana)

Cuba Time uses CST at UTC-5 and CDT at UTC-4 during daylight saving time, but Cuba sets its own DST transition dates independently of the United States. Cuba typically begins DST in March and ends it in early November, but the exact dates have varied by government decree. This independence in DST scheduling occasionally puts Cuba out of sync with neighboring Caribbean nations and the US. Havana, the capital, is one of the Caribbean's most historically significant cities, with a UNESCO World Heritage old town. Cuba's timezone history reflects its unique political position — as one of the few communist states in the Western Hemisphere, it has sometimes used timezone changes as symbols of national sovereignty or to address energy concerns. The island's economy relies heavily on tourism, sugar, tobacco, and nickel exports. Cuba's timezone is important for international telecommunications, aviation routes through Cuban airspace, and the significant Cuban diaspora in Miami and other US cities who maintain close contact with family on the island.
