CST-CUBA to LHST Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Cuba Standard Time and Lord Howe Time don't overlap on the same weekday. Lord Howe Time is 15 hours ahead of Cuba Standard Time.

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

• 5 PM–8 PM in Cuba Standard Time (7 AM–10 AM the next day in Lord Howe Time) — suggest 6:00 PM Cuba Standard Time (8:30 AM Lord Howe Time).

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

Cuba Standard Time is also known as CST, or CDT. To call Cuba, dial +53.

Lord Howe Time is also known as LHST, or LHDT. To call Australia, dial +61.

Lord Howe Time is approximately 8,650 miles southwest of Cuba Standard Time.

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

Cuba Standard Time: next transition on Sunday, November 1, 2026.

Lord Howe Time: next transition on Sunday, October 4, 2026.

Cuba Standard Time and Lord Howe Time 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.
