Timezone abbreviation
ICT currently resolves here through Asia/Ho_Chi_Minh, where the live offset is +07:00 (GMT+7). This page expands that into the broader meaning set, top cities, countries, similar labels, and safer exact-zone equivalents.
Representative zones, offset ranges, and city usage are refreshed from the current timezone dataset so abbreviation pages stay tied to real zones instead of static boilerplate.
ICT is an Asian civil-time label, currently 7h ahead of UTC at +07:00. The lead reference is Ho Chi Minh City, and the wider grouping reaches 4 countries through 4 IANA zones.
The busiest cities using ICT in the current catalog are Ho Chi Minh City, Hanoi, Bangkok, Haiphong, and Phnom Penh. The lead live reference on this page is Ho Chi Minh City (Asia/Ho_Chi_Minh), currently at +07:00 (GMT+7). Those cities are what give ICT its actual feel rather than the abstract offset.
ICT has a local identity beyond its offset: mainland Southeast Asia through Thailand, Vietnam, Cambodia, and Laos. Calendar signals such as Songkran, Tet, Khmer New Year, and Pi Mai Lao and operational signals such as Bangkok tourism, Vietnam manufacturing, Cambodia and Laos government scheduling, and Mekong-region support handoffs are why this abbreviation should not be flattened into a same-offset neighbor.
ICT is stable on Asia/Ho_Chi_Minh year-round, with no seasonal clock changes in the next year. That makes it a low-friction choice for recurring meetings and broadcast schedules — but software still prefers the IANA zone because governments can change civil-time rules independently of the short code.

ICT is well ahead of UTC, which usually means it is read inside Asia, the Middle East, or the Indian Ocean rim. In practice it is read inside Southeast Asia, where the leading city anchors are Ho Chi Minh City, Vietnam, Hanoi, Vietnam, and Bangkok, Thailand.
ICT maps to a single conceptual meaning, but it spans 4 IANA zones — small DST and historical-rule differences between those zones are why timestamp systems should still pin to the exact zone.
ICT shows up in regional aviation, ASEAN-wide media schedules, and cross-border logistics notes. ICT stays on a single offset year-round in the current data, which simplifies its operational use.

Abbreviation dossier
These checks separate the abbreviation from lookalike labels and same-offset codes: the representative IANA zone, the current civil-time reading, the city/country footprint, and whether the lead zone has an upcoming clock change.
Primary live reading
Indochina Time resolves through Asia/Ho_Chi_Minh right now: +07:00 (GMT+7).
Ambiguity status
ICT maps to one meaning in this catalog, but the IANA zone still matters because clock-change rules live on the zone, not the short code.
DST and transition posture
Asia/Ho_Chi_Minh has no scheduled offset switch in the next year in this snapshot.
Country and city reach
ICT is represented across 4 countries, 4 IANA zones, and lead cities including Ho Chi Minh City, Vietnam, Hanoi, Vietnam, and Bangkok, Thailand.
Same-offset caution
ICT and CXT currently share +07:00, but they point at different civil-time labels, cities, countries, and source contexts. Treat the matching offset as arithmetic only, not semantic equivalence.
Editorial check
Indochina-specific reading: Use Asia/Bangkok, Asia/Ho_Chi_Minh, Asia/Phnom_Penh, or Asia/Vientiane when the country matters.
Precision layer
Timezone abbreviations are useful display labels, but they are weak storage keys. This register shows the exact risks for ICT: ambiguity, seasonal changes, same-offset neighbors, and the safer value to store in software, calendars, or operations notes.
Abbreviation ambiguity risk
MediumICT has one meaning in this catalog, but the zone and country context still carry the legal-time rule.
Seasonal clock-change risk
LowAsia/Ho_Chi_Minh is stable for the next-year transition scan, so the main risk is policy change or same-offset confusion.
Same-offset confusion risk
Medium5 other abbreviation pages currently share +07:00; the same clock hour is not the same civil-time context.
Storage recommendation
Use exact zoneStore Asia/Ho_Chi_Minh or a UTC instant. Display ICT only as a human-facing label after the exact zone is known.
Coverage breadth

Four fixed UTC checkpoints expose whether ICT crosses a local date boundary in Asia/Ho_Chi_Minh. This is the practical difference between a harmless clock conversion and a deadline, release, travel, or reporting mistake.

Editorial disambiguation
ICT is Indochina Time across Thailand, Vietnam, Cambodia, and Laos. It shares UTC+7 with Western Indonesia Time, but the user intent is different: Bangkok tourism, Ho Chi Minh City and Vietnam manufacturing, Phnom Penh and Vientiane government timing, Mekong-region support handoffs, Songkran, Tet, Khmer New Year, Pi Mai Lao, and country-specific holidays. A plain UTC+7 conversion misses the mainland Southeast Asia calendar that usually explains why someone searched for ICT.
Vietnam sits in Asia, specifically South-Eastern Asia. Population 101,343,800, area 331,212 km², capital Hanoi. Civic markers behind ICT include Vietnamese and VND (Vietnamese đồng, ₫).
Vietnam is linked as the country-level reference source for ICT; the civic context above is drawn from structured country fields rather than copied reference prose.
ICT in the Indochina Time meaning runs 7h ahead of UTC through Southeast Asia, threading zones such as Asia/Bangkok, Asia/Ho_Chi_Minh, and Asia/Phnom_Penh (cities: Ho Chi Minh City, Hanoi, and Bangkok). Country anchors: Vietnam, Thailand, and Cambodia.

ICT resolves cleanly here, but Asian labels often share letters with American or European ones — IST is shared between India and Israel, for instance. Pinning Asia/Ho_Chi_Minh avoids that whole class of confusion.
ICT is fixed at UTC+07 in the current data, with the practical legal context split across four national calendars. Not the same as WIB: the offset matches western Indonesia, but the languages, holidays, currencies, and regional operating assumptions are different.
Asia/Ho_Chi_Minh does not show an offset change in the next year, which makes ICT predictable for short-term scheduling. Predictable is not the same as permanent — civil-time rules still get changed by governments on relatively short notice.
For precise work, the safest equivalent of ICT is the exact IANA zone used by your city or system. Asia/Ho_Chi_Minh sits at +07:00, ahead of UTC, which means daily logs in this zone reach a new calendar date before UTC does — a small detail that breaks date-based reporting if missed.
Even with one canonical meaning, ICT spans 4 IANA zones — pin to Asia/Ho_Chi_Minh when DST or historical-rule precision matters.
