Havana to Sydney Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Havana and Sydney don't overlap on the same weekday. Sydney is 14 hours ahead of Havana.

With some flexibility, there’s a workable window outside standard hours:

• 5 PM–8 PM in Havana (7 AM–10 AM the next day in Sydney) — suggest 6:00 PM Havana (8:00 AM Sydney).

This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.

Havana uses Cuba Standard Time (CST, or CDT). To call Cuba, dial +53.

Sydney uses Australian Eastern Time (AEST, or AEDT). To call Australia, dial +61.

Sydney is approximately 9,150 miles southwest of Havana.

Both zones observe daylight saving time, but they transition on different dates.

Havana: next transition on Sunday, November 1, 2026.

Sydney: next transition on Sunday, October 4, 2026.

Havana and Sydney are in opposite hemispheres, so their clocks change in opposite directions about six months apart — one springs forward while the other falls back. The offset between them therefore shifts twice a year and can swing by up to two hours across the seasons, more than a typical same-hemisphere pair. Recurring meetings will need re-checking after each transition.

See the daylight saving time page for transition dates across every time zone.
