There is no time difference between Zanzibar and Dar es Salaam. Both use East Africa Time (EAT, UTC+3). When it's 12:00 PM in Zanzibar, it's also 12:00 PM in Dar es Salaam.
Tanzania does not observe daylight saving time, so these cities remain synchronized year-round.
Any time works! Since both cities share the same timezone, you can schedule calls during standard business hours (9:00 AM - 5:00 PM) without any time conversion needed.
Zanzibar is a semi-autonomous archipelago off the coast of mainland Tanzania, with Dar es Salaam being the largest city and commercial hub of the country. Ferries connect Zanzibar to Dar es Salaam in about 2 hours, and both are popular tourist and business destinations.
