Adelaide & Havana — Business & Scheduling Guide

Adelaide (Australia) is a stable, resource-rich economy in the Asia-Pacific region, with key industries in mining, agriculture, finance, and tourism. Havana (Cuba) is a Caribbean economy undergoing gradual economic opening, known for tourism, biotechnology, agriculture (sugar, tobacco), and nickel. 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 Adelaide and Havana

With Havana 14.5 hours behind Adelaide, 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. Australian work culture values work-life balance, with typical hours of 9 AM–5 PM and flexible arrangements common. Cuban business hours are typically 8 AM–5 PM, with a well-educated workforce and growing private sector. Consider recording meetings for those who can't attend live, and use shared documents for async collaboration.

Daylight Saving Time Considerations

Both Adelaide and Havana observe Daylight Saving Time. Adelaide uses ACST/ACDT (switching between standard and daylight time), while Havana uses CST/CDT. 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, Adelaide and Havana 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 Adelaide and Havana.

Remote Work Between Adelaide & Havana

Adelaide, a key city in Australia, and Havana, a key city in Cuba, 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 Adelaide and Havana.
