Melbourne to GMT Converter

Standard business hours (9 AM–5 PM, Mon–Fri) in Melbourne and Greenwich Mean Time don't overlap on the same weekday. Greenwich Mean Time is 9 hours behind Melbourne.

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

• 4 PM–8 PM in Melbourne (7 AM–11 AM in Greenwich Mean Time) — suggest 6:00 PM Melbourne (9:00 AM Greenwich Mean Time).

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

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

Greenwich Mean Time is also known as GMT, or BST. To call United Kingdom, dial +44.

Greenwich Mean Time is approximately 10,500 miles northwest of Melbourne.

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

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

Greenwich Mean Time: next transition on Sunday, October 25, 2026.

Melbourne and Greenwich Mean 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.
