SGT ↔ GST Time Converter

Gulf Standard Time (GST) is 4h behind of Singapore Standard Time (SGT). SGT runs at UTC+8 and GST at UTC+4. Quick time examples: 8:00 AM SGT = 4:00 AM GST; 12:00 PM SGT = 8:00 AM GST; 5:00 PM SGT = 1:00 PM GST.

To convert SGT to GST, subtract 4 hours to the SGT time. For example, 12:00 PM SGT becomes 8:00 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 4h behind of Singapore Standard Time (SGT). Reversed: SGT is 4h ahead of GST. Practical example: noon in Dubai (12:00 PM GST) corresponds to 4:00 PM SGT in Singapore, and 5 PM in Dubai corresponds to 9:00 PM SGT.

Singapore Standard Time (SGT) is the standard civil time for Singapore and the surrounding region, operating at UTC+8 from UTC. It does not observe Daylight Saving Time; the UTC offset stays at UTC+8 every day of the year. Major cities: Singapore, Kuala Lumpur, Penang, Johor Bahru, George Town, Ipoh, Kuching.

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.

No — and this makes SGT–GST one of the simpler pairs to schedule across. Neither zone observes Daylight Saving Time, so the offset is exactly 4h behind every single day of the year. You can set up a recurring calendar invite once and never adjust it for seasonal clock changes on either side.

The best meeting window is where standard working hours (9 AM – 6 PM) overlap in both zones. Since GST is 4h behind of SGT, 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 SGT result. Alternatively, add 4 hours from the GST time manually. For a dedicated reverse page, visit: GST to SGT converter ↗.

For some hours of the day the conversion does cross midnight into the next or previous calendar day. 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.

Singapore Standard Time (SGT) is used in: Singapore, Kuala Lumpur, Penang, Johor Bahru, George Town, Ipoh, Kuching. The zone operates at UTC+8, with a constant offset all year.

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.

Yes — since neither SGT nor GST observes DST, the offset is exactly 4h behind every day of the year without exception.

When creating a recurring meeting that spans SGT and GST, set the event timezone in your calendar app using the IANA timezone names: Asia/Singapore for SGT 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.

No. Singapore has not observed Daylight Saving Time since 1982 and has maintained a fixed UTC+8 offset ever since. This makes SGT particularly easy to work with for recurring international meetings — the SGT side of any timezone pair is always exactly UTC+8, with no seasonal variation. SGT aligns numerically with Hong Kong Time (HKT), China Standard Time (CST8), Philippine Standard Time, and Australian Western Standard Time (AWST).

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.
