ICT — Indochina Time
See what ICT means, its UTC+7 offset, whether it uses daylight saving time, and how to convert ICT to other time zones.
How to Convert ICT to Other Time Zones
Open the ICT converter page: Go to https://www.xconvert.com/time-converter/ict to open the visual comparison grid with ICT (Indochina Time, UTC+7) already loaded as the main row. This page is useful when you are planning a supplier call in Bangkok, coordinating manufacturing updates with teams in Ho Chi Minh City, or checking whether a support handoff to Jakarta or Singapore fits normal office hours.
Add comparison cities: Click “+ Add City” and search for cities that commonly interact with ICT-based schedules, such as London for trade and logistics, Dubai for aviation and regional commerce, or New York for global clients and headquarters teams. If you work in apparel sourcing, electronics manufacturing, tourism, or cross-border e-commerce, these comparisons help you see immediately whether a daytime slot in mainland Southeast Asia lands in another region’s workday or late-night hours.
Select a time range on the grid: Click “Select” if needed, then drag across the ICT row to highlight a meeting window, such as 9:00 AM to 11:00 AM ICT. That selection shows the real overlap in other zones—for example, 9:00 AM ICT is 2:00 AM in London during GMT, 3:00 AM in London during BST, 5:00 AM in Dubai, and 9:00 PM in New York the previous day during EST or 10:00 PM during EDT—which quickly confirms whether a Southeast Asia morning meeting is practical for Europe or North America.
Export and share the result: After selecting the time block, use the export options shown by the tool: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful if you need to send a confirmed slot to a distributed operations team, attach an ICS file so calendars convert automatically into local time, or paste the shared link into Slack or email for a regional handoff between Asia, Europe, and the US.
About Indochina Time (ICT)
ICT stands for Indochina Time, a standard time zone with a fixed offset of UTC+7:00. That means local time in ICT is always 7 hours ahead of Coordinated Universal Time (UTC), so when it is 12:00 noon UTC, it is 7:00 PM ICT.
Indochina Time is used in mainland parts of Southeast Asia, most notably by Thailand, Vietnam, Cambodia, and Laos. In practical terms, major business centers operating on ICT include Bangkok, Ho Chi Minh City, Hanoi, Phnom Penh, and Vientiane, making UTC+7 one of the most important time standards for regional manufacturing, tourism, food exports, and supply-chain coordination.
ICT is 1 hour behind China Standard Time (UTC+8), 2 hours behind Japan Standard Time (UTC+9), and 3 hours 30 minutes ahead of India Standard Time (UTC+5:30). For example, when it is 9:00 AM in Bangkok or Ho Chi Minh City, it is 8:00 AM in Singapore? No—Singapore uses UTC+8, so it is actually 10:00 AM there; at the same moment it is 11:00 AM in Tokyo and 5:30 AM in New Delhi. These differences matter for export documentation, airline schedules, and remote team standups across Asia.
Although ICT is a named regional time zone, the same UTC+7 offset is also shared by other abbreviations in different places or contexts, including WIB, along with listed same-offset abbreviations such as CXT, DAVT, G, HOVT, KRAT, NOVST, NOVT, OMSST, and WIB. Sharing an offset does not mean the zones are identical in legal usage or seasonal behavior, so scheduling should always be based on the city or region, not the abbreviation alone.
ICT and Daylight Saving Time
Indochina Time does not observe daylight saving time. Its DST status is false, which means ICT stays on UTC+7:00 all year and does not switch forward in spring or back in autumn.
For the current year, 2026, ICT has no DST transition dates. There is no switch to a summer time, no switch back to a winter time, and no clock change on any date in 2026, which makes it easier to schedule recurring meetings with Bangkok, Hanoi, or Phnom Penh than with cities in Europe or North America that shift seasonally.
The main complication with ICT scheduling comes from other regions changing their clocks while ICT stays fixed. For example, the time difference between ICT and London is 7 hours during GMT but only 6 hours during British Summer Time, while the gap between ICT and New York is 12 hours during EST and 11 hours during EDT. If you run recurring calls with teams in the UK or US, the local meeting time on their side will move when their DST rules change, even though ICT remains unchanged.
Frequently Asked Questions
What does ICT stand for?
ICT stands for Indochina Time. It is the standard time zone used by several mainland Southeast Asian countries, including Thailand, Vietnam, Cambodia, and Laos, all of which operate on UTC+7 year-round.
Is ICT the same as GMT?
No, ICT is not the same as GMT. GMT is UTC+0, while ICT is UTC+7, so ICT is 7 hours ahead of GMT; when it is 9:00 AM GMT in London during winter, it is 4:00 PM ICT in Bangkok or Hanoi.
Which cities use ICT?
Major cities using ICT include Bangkok, Ho Chi Minh City, Hanoi, Phnom Penh, and Vientiane. These cities are important regional hubs for tourism, manufacturing, government, and trade, so ICT often appears in airline schedules, factory coordination, and cross-border business planning across Southeast Asia.
What is the UTC offset for ICT?
The UTC offset for ICT is UTC+7:00. This means ICT is always 7 hours ahead of UTC, so 6:00 AM UTC converts to 1:00 PM ICT, and 11:00 PM UTC converts to 6:00 AM ICT the next day.
When does ICT change?
ICT does not change during the year because it does not observe daylight saving time. In 2026, there are no DST start dates and no DST end dates, so clocks in ICT-based regions remain on UTC+7 from January through December.
Is ICT the same as UTC+7?
In offset terms, ICT is a UTC+7 time zone, so the clock time matches other places using UTC+7 at that moment. However, it is still better to schedule by city name—such as Bangkok or Ho Chi Minh City—because different regions with the same offset can use different abbreviations, legal definitions, or historical rules.
How far ahead is ICT from New York or London?
ICT is usually 12 hours ahead of New York during EST and 11 hours ahead during EDT. It is 7 hours ahead of London during GMT and 6 hours ahead during BST, so a 3:00 PM meeting in ICT is 8:00 AM in London during winter, 9:00 AM in London during summer, 3:00 AM in New York during winter, and 4:00 AM in New York during summer.
Why is ICT useful for international business scheduling?
ICT covers several economies deeply connected to global supply chains, including garment production, electronics assembly, tourism, agriculture, and regional logistics. Because ICT does not shift for daylight saving time, it provides a stable reference point for recurring calls with factories in Thailand or Vietnam, though teams in Europe and North America still need to adjust when their own DST dates change.
