How Time Zone Conversion Works
Time zone conversion works by comparing the UTC offset of one location to another. Every city or region is measured relative to Coordinated Universal Time (UTC), which acts as the global reference point for civil time.
GMT is 11 hours behind AEDT (standard time).
Daylight Saving Time: Both AEDT and GMT observe DST, but on opposite-hemisphere schedules. When one springs forward, the other falls back — so the offset shifts four times per year instead of the usual two.

AEDT is the daylight-saving designation used in southeastern Australia; Queensland remains on AEST (UTC+10) year-round and is not represented by this code. Two Australian territories have unusual DST offsets: Lord Howe Island (NSW) uses UTC+10:30 in winter and UTC+11 in summer — the only jurisdiction in the world with a 30-minute DST shift; Norfolk Island uses UTC+11 in winter and UTC+12 in summer, following the same transition dates as eastern states.

GMT countries vary. The UK, Ireland, and Portugal observe summer time; Iceland and most of West Africa remain on GMT year-round.
