Havana & Adelaide — Business & Scheduling Guide
Havana (Cuba) is a Caribbean economy undergoing gradual economic opening, with key industries in tourism, biotechnology, agriculture (sugar, tobacco), and nickel. Adelaide (Australia) is a stable, resource-rich economy in the Asia-Pacific region, known for mining, agriculture, finance, and tourism. With a 14.5-hour time difference, professionals frequently schedule cross-border calls between these two cities for international trade, remote team collaboration, and client meetings.
Scheduling Meetings Between Havana and Adelaide
With Adelaide 14.5 hours ahead of Havana, there is minimal overlap in standard business hours. Most teams alternate meeting times to share the burden of early-morning or late-evening calls fairly. Cuban business hours are typically 8 AM–5 PM, with a well-educated workforce and growing private sector. Australian work culture values work-life balance, with typical hours of 9 AM–5 PM and flexible arrangements common. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.
Daylight Saving Time Considerations
Both Havana and Adelaide observe Daylight Saving Time. Havana uses CST/CDT (switching between standard and daylight time), while Adelaide uses ACST/ACDT. If their DST transitions happen on different dates — which is common, as the US, EU, and other regions change clocks on different weekends — the effective time difference between the two cities can shift by 1 hour for several weeks. Always double-check the actual offset during March–April and October–November.
Collaboration Tools & Workflow
With a 14.5-hour time difference, Havana and Adelaide teams operate in a near "follow-the-sun" model. When one team logs off, the other picks up — enabling near-24-hour productivity on shared projects. The key challenge is handoff quality: teams should document decisions in shared tools (Notion, Confluence, Linear), record video updates with Loom, and write thorough pull request descriptions. Weekly all-hands meetings require someone to take an early morning or late evening call, so the best practice is to rotate this burden fairly between Havana and Adelaide.
Remote Work Between Havana & Adelaide
Havana, a key city in Cuba, and Adelaide, a key city in Australia, represent a common corridor for distributed teams navigating a 14.5-hour time difference. Remote workers and freelancers operating between these cities should plan their day around the overlap window — typically the late morning for one city and early morning or late afternoon for the other. Using a world clock widget, setting Slack status with local time, and blocking "no-meeting" deep work hours outside the overlap are essential practices for productive cross-timezone remote collaboration between Havana and Adelaide.
