When to schedule
Standard business hours (9 AM–5 PM, Mon–Fri) in Havana and Melbourne don't overlap on the same weekday. Melbourne 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 Melbourne) — suggest 6:00 PM Havana (8:00 AM Melbourne).
This means an early start or late finish for one side, but it’s a reasonable slot for a one-off meeting.
This window may shift by an hour during daylight saving time.
Public holidays in 2026
National public holidays can affect availability — a counterpart is likely off work on their own holidays, so it's worth planning meetings and deadlines around them.

Daylight saving time
Both zones observe daylight saving time, but they transition on different dates.
Havana: next transition on Sunday, November 1, 2026.
Melbourne: next transition on Sunday, October 4, 2026.
Havana and Melbourne 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.
