Why people convert Melbourne to London time
- Scheduling a call from Melbourne to London: a 10:00 AM start in Melbourne lands at 1:00 AM in London, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -9h gap: Melbourne and London have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in London is 12:00 AM in Melbourne.
- Coordinating a Melbourne-based team with London contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM AEST" is unambiguous; "3 PM" across a -9h gap is not.
- With a -9h gap there is no shared 9-to-5 window, so alternate the early start: one week Melbourne takes the early slot, the next week London does.
- Melbourne: Clocks spring forward on Sat, Oct 3, 2026. Re-check this page after that date because the offset changes and so does the -9h gap.
- London: Clocks fall back on Sun, Oct 25, 2026. Any meeting series spanning that date will shift by an hour in local time.
