SGT ↔ ICT Time Converter

Indochina Time (ICT) is 1h behind of Singapore Standard Time (SGT). SGT runs at UTC+8 and ICT at UTC+7. Quick time examples: 8:00 AM SGT = 7:00 AM ICT; 12:00 PM SGT = 11:00 AM ICT; 5:00 PM SGT = 4:00 PM ICT.

To convert SGT to ICT, subtract 1 hour to the SGT time. For example, 12:00 PM SGT becomes 11:00 AM ICT. 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.

Indochina Time (ICT) is 1h behind of Singapore Standard Time (SGT). Reversed: SGT is 1h ahead of ICT. Practical example: noon in Bangkok (12:00 PM ICT) corresponds to 1:00 PM SGT in Singapore, and 5 PM in Bangkok corresponds to 6:00 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.

Indochina Time (ICT) covers Bangkok and the surrounding region at UTC+7 from UTC. It does not observe Daylight Saving Time — the offset is fixed at UTC+7 all year with no seasonal change. Cities in this zone: Bangkok, Ho Chi Minh City, Hanoi, Phnom Penh, Vientiane, Jakarta, Medan.

No — and this makes SGT–ICT one of the simpler pairs to schedule across. Neither zone observes Daylight Saving Time, so the offset is exactly 1h 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 ICT is 1h 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 ICT field in the bidirectional converter above — it instantly shows the SGT result. Alternatively, add 1 hour from the ICT time manually. For a dedicated reverse page, visit: ICT 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.

Indochina Time (ICT) covers: Bangkok, Ho Chi Minh City, Hanoi, Phnom Penh, Vientiane, Jakarta, Medan. It runs at UTC+7, 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 ICT observes DST, the offset is exactly 1h behind every day of the year without exception.

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