Vietnam Time Zone: Indochina Time (ICT)
Vietnam operates on Indochina Time (ICT), which is UTC+7 (GMT+7). This time zone is shared with Thailand, Laos, and Cambodia. Importantly, Vietnam does not observe daylight saving time, so the offset from UTC remains +7 hours throughout the entire year.
Time in Hanoi vs Ho Chi Minh City
Unlike some large countries, Vietnam uses a single time zone for the entire country. This means Hanoi (in the north), Da Nang (in the center), and Ho Chi Minh City (in the south) all share the exact same local time. There is no time difference between Vietnamese cities.
History of Vietnam's Time Zone
Vietnam briefly used UTC+8 during the 1970s but switched back to UTC+7 in 1975 after reunification. The country has maintained ICT (UTC+7) ever since. Vietnam is one of the few countries in Southeast Asia that has never adopted daylight saving time.
