When the difference changes

Gulf Standard Time and Australian Eastern Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

Now – October 3, 2026Australian Eastern Time is 6 hours ahead
October 3, 2026 – April 3, 2027Australian Eastern Time is 7 hours ahead
April 3, 2027 – October 2, 2027Australian Eastern Time is 6 hours ahead
October 2, 2027 – onwardsAustralian Eastern Time is 7 hours ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

Daylight saving

Gulf Standard Time

No clock changes

Gulf Standard Time stays on GST all year, so its offset from UTC never moves.

Australian Eastern Time

Sunday, October 4, 2026

Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on AEDT after that.

Gulf Standard Time (GST) is used in the UAE and Oman

Australian Eastern Time (AEST) is used in Melbourne, Canberra and Brisbane. Queensland stays on AEST all year while the southern states move to AEDT.
