UTC and ICT on the World Map
The map below highlights the UTC (Coordinated Universal Time) and ICT (Indochina Time) timezone regions across the globe.
UTC – Coordinated Universal Time
UTC+00:00Coordinated Universal Time (UTC) is the world's primary time standard, used as the basis for civil time worldwide.
- •UTC is the basis for all civil time zones worldwide.
- •The abbreviation 'UTC' is a compromise between English (CUT) and French (TUC).
- •UTC is based on atomic clocks and is accurate to within a nanosecond per day.
- •Servers and databases worldwide store timestamps in UTC to avoid timezone confusion.
- •Leap seconds are occasionally added to UTC to keep it aligned with Earth's rotation.
ICT – Indochina Time
UTC+07:00Indochina Time (ICT) is the time zone for Vietnam, Thailand, Laos, and Cambodia, 7 hours ahead of UTC.
- •Bangkok is one of the most visited cities in the world.
- •ICT is 12 hours ahead of EST.

UTC vs Vietnam: Offsets, DST and Best Call Times
UTC runs on Coordinated Universal Time (UTC) at UTC+00:00. Vietnam runs on Indochina Time (ICT) at UTC+07:00. That puts UTC 7 hours ahead of Vietnam — a difference of +7h at the current offsets.
In practice, when it is 9:00 AM in UTC it is 4:00 PM in Vietnam. Midnight in UTC is 7:00 AM in Vietnam. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert UTC to Vietnam time
- Scheduling a call from UTC to Vietnam: a 10:00 AM start in UTC lands at 5:00 PM in Vietnam, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both UTC and Vietnam are inside the 9-to-5 working day between 9:00 AM and 10:00 AM UTC time (4:00 PM–5:00 PM ICT). That is roughly 1 hours of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in UTC is 3:00 AM in Vietnam makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM UTC" is unambiguous; "3 PM" across a +7h gap is not.
- Block 9:00 AM–10:00 AM UTC as the recurring meeting window if you work primarily from UTC and need Vietnam colleagues present.
About UTC (Coordinated Universal Time)
Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time. It is effectively the successor to GMT and is based on International Atomic Time with leap seconds added to keep it synchronized with Earth's rotation. UTC is used in aviation, computing, navigation, weather forecasting, and the International Space Station. Most programming languages and databases store timestamps in UTC.
About ICT (Indochina Time)
Indochina Time (ICT) is used across Southeast Asia including Vietnam, Thailand, Laos, and Cambodia. Indonesia (Western time, WIB) also uses UTC+07:00. ICT does not observe daylight saving time.
Best time to call between UTC and Vietnam
Both UTC and Vietnam sit inside the 9 AM – 5 PM working day between 9:00 AM–10:00 AM UTC, which is 4:00 PM–5:00 PM ICT. That gives roughly 1 hours of shared time — the safest window for a live call or meeting.
Business hours overlap
UTC and Vietnam overlap for only 60 minutes (9:00 AM–10:00 AM UTC), so meetings have to be booked precisely.
UTC is 7 hours ahead of Vietnam (UTC UTC+00:00 → ICT UTC+07:00). The shared working window is 9:00 AM–10:00 AM UTC. Remember to re-check around daylight-saving transitions.
