Business Hours & Working Day in Cuba

Standard business hours in Cuba typically run from 9:00 AM to 5:00 PM local time, Monday through Friday. Since the entire country shares the exact same time, coordinating with contacts across different cities is easy. As long as it is within working hours in Havana, it is working hours everywhere else in the country.

Daylight Saving Time (DST) Rules

Parts or all of Cuba observe Daylight Saving Time (DST). During the warmer months, clocks are moved forward by one hour to make better use of evening daylight. When DST is in effect, both sunrise and sunset occur one hour later according to the clock. For international callers, these transitions directly affect the time difference with countries that do not observe DST, which can unexpectedly shift regular meeting schedules by an hour.
