AEST ↔ GST Time Converter

Gulf Standard Time (GST) is 6h behind of Australian Eastern Standard Time (AEST). AEST runs at UTC+10 / UTC+11 (AEDT) and GST at UTC+4. Quick time examples: 8:00 AM AEST = 2:00 AM GST; 12:00 PM AEST = 6:00 AM GST; 5:00 PM AEST = 11:00 AM GST.

To convert AEST to GST, subtract 6 hours to the AEST time. For example, 12:00 PM AEST becomes 6:00 AM GST. When the result crosses midnight, advance the date by one day (shown as "+1 Day" in the converter). The converter on this page handles all arithmetic and date-rollover automatically.

Gulf Standard Time (GST) is 6h behind of Australian Eastern Standard Time (AEST). Reversed: AEST is 6h ahead of GST. Practical example: noon in Dubai (12:00 PM GST) corresponds to 6:00 PM AEST in Sydney, and 5 PM in Dubai corresponds to 11:00 PM AEST.

Australian Eastern Standard Time (AEST) is the standard civil time for Sydney and the surrounding region, operating at UTC+10 / UTC+11 (AEDT) from UTC. It observes Daylight Saving Time and advances its clocks by one hour during summer — the effective offset changes seasonally. Major cities: Sydney, Melbourne, Brisbane, Canberra, Hobart, Newcastle, Gold Coast.

Gulf Standard Time (GST) covers Dubai and the surrounding region at UTC+4 from UTC. It does not observe Daylight Saving Time — the offset is fixed at UTC+4 all year with no seasonal change. Cities in this zone: Dubai, Abu Dhabi, Sharjah, Muscat, Doha, Bahrain, Kuwait City.

Yes. AEST observes Daylight Saving Time and moves its clocks by one hour in summer, while GST stays fixed at UTC+4 all year. This means the offset between the two zones shifts by one hour when AEST enters or exits its DST period. The live converter on this page always shows the current accurate offset.

The best meeting window is where standard working hours (9 AM – 6 PM) overlap in both zones. Since GST is 6h behind of AEST, mornings in the earlier zone align with afternoons or evenings in the later zone. Target 8 AM – 11 AM in the earlier-offset zone to keep both sides in reasonable hours. The meeting hours table above shows the exact recommended slots for this pair. Any time where one side falls before 7 AM or after 9 PM is best avoided for regular team calls.

Type any time directly into the GST field in the bidirectional converter above — it instantly shows the AEST result. Alternatively, add 6 hours from the GST time manually. For a dedicated reverse page, visit: GST to AEST converter ↗.

Yes — this is a large offset, and many hours will cross midnight. When the converted time passes 11:59 PM, the date advances — the converter shows "+1 Day". When it goes before 12:00 AM, the date moves back — "-1 Day" appears. The 24-hour reference table also shows day changes in the Day column. Always check the date indicator when sending calendar invites across these two zones to avoid accidentally booking on the wrong date.

Australian Eastern Standard Time (AEST) is used in: Sydney, Melbourne, Brisbane, Canberra, Hobart, Newcastle, Gold Coast. The zone operates at UTC+10 / UTC+11 (AEDT)and shifts by one hour during DST.

Gulf Standard Time (GST) covers: Dubai, Abu Dhabi, Sharjah, Muscat, Doha, Bahrain, Kuwait City. It runs at UTC+4, fixed year-round with no DST change. Use the live clocks at the top of this page to see the current local time in both zones side by side.

The standard offset is 6h behind, but this can shift by one hour during DST transition periods. When AEST moves to or from its daylight variant, the gap changes. The live converter always shows the current accurate offset.

When creating a recurring meeting that spans AEST and GST, set the event timezone in your calendar app using the IANA timezone names: Australia/Sydney for AEST and Asia/Dubai for GST. Using IANA names rather than fixed UTC offsets ensures the calendar app automatically adjusts future occurrences for any DST changes, so you never accidentally schedule at the wrong time after a clock transition. For a quick lookup of any specific time, the converter on this page is the fastest way to verify both sides before you send the invite.

AEST (Australian Eastern Standard Time) is UTC+10 and applies during Australian winter (approximately April to October). AEDT (Australian Eastern Daylight Time) is UTC+11 and applies during Australian summer (October to April), when New South Wales, Victoria, Tasmania, and the ACT move their clocks forward. Queensland does not observe DST and stays at AEST/UTC+10 all year. The live converter on this page uses the Sydney/Melbourne zone which switches between AEST and AEDT automatically — if you are scheduling specifically with Brisbane (Queensland), subtract one hour from any AEDT result during the October–April period.

No. Gulf Standard Time (GST) countries — the UAE, Oman, Bahrain, and Qatar — do not observe Daylight Saving Time. GST stays at UTC+4 all year without exception. This makes the Gulf a very stable timezone anchor for scheduling between Africa/Europe on one side and Asia on the other — the offset never shifts.
