Daylight saving time note
Dubai and Sydney do not change their clocks on the same date. Between October 3, 2026 and April 3, 2027 the difference is 7 hours behind Sydney — because Sydney changes its clocks for daylight saving time while Dubai keeps the same time all year.
For the rest of the year the difference holds steady at 6 hours. Every time on this page is computed from the IANA database at the moment you load it, so the tables above already account for whichever side has switched.
Why the time difference exists
Dubai keeps standard time at UTC+4, while Sydney runs on UTC+10. Only Sydney shifts for daylight saving; Dubai stays put, which nudges the difference by an hour twice a year. Sydney sits roughly 12,000 km to the southeast of Dubai.
Expect roughly a 6 hours forward adjustment travelling from Dubai to Sydney. The direct distance works out to roughly 15 hours in the air. Line up a shared window before you call and the rest is easy.
