Open the Vietnam time converter: Go to https://www.xconvert.com/time-converter/vietnam to load Vietnam with its standard national time centered on Hanoi. This page is useful when you need to schedule a supplier call in Ho Chi Minh City, confirm a support handoff with a team in Hanoi, or check whether Vietnam business hours overlap with offices in Singapore, London, or New York.
Add comparison cities with the + Add City button: Click + Add City and search for cities such as Singapore, Tokyo, and London to compare Vietnam with major trade, manufacturing, and finance hubs. Singapore is relevant for regional headquarters and shipping, Tokyo for electronics and industrial supply chains, and London for international clients who need to know whether a 3 PM Vietnam meeting lands inside or outside UK office hours.
Drag across the grid to select a meeting window: Use the Select button if needed, then drag across Vietnam’s row from 9:00 AM to 11:00 AM ICT to highlight a work block in purple. That selection shows a concrete overlap: Vietnam is UTC+7, so 9 AM in Vietnam is 2 AM UTC, 10 AM in Hanoi is 11 AM in Tokyo during Japan’s standard year-round UTC+9, and 9 AM in Vietnam is 3 AM in London during GMT or 4 AM during British Summer Time, which quickly tells you that a Vietnam morning call is practical for East Asia but usually too early for Europe.
Export the selected time for your team: After selecting the range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful for cross-border manufacturing, software outsourcing, or logistics coordination, because an ICS file or Google Calendar link lets colleagues in Vietnam, Europe, and North America see the meeting automatically in their own local time without manually converting ICT.

Time Zones in Vietnam

Vietnam uses one time zone nationwide: Indochina Time (ICT), which is UTC+7. Unlike countries such as the United States or Russia, Vietnam does not split its territory into multiple official time zones, even though the country stretches more than 1,600 kilometers from north to south along the eastern edge of mainland Southeast Asia.

A key practical point is that Vietnam does not use a half-hour or quarter-hour offset. Its national time is a whole-hour offset from UTC, so it is simpler to compare than places such as India (UTC+5:30) or Nepal (UTC+5:45). This means when it is 9:00 AM in Hanoi or Ho Chi Minh City, it is 2:00 AM UTC, 3:00 PM in Los Angeles the previous day during PST, or 5:00 PM the previous day during CST in Chicago.

Vietnam also does not observe daylight saving time, so ICT remains UTC+7 all year. That stability is useful for remote teams and travel planning because the time in Hanoi, Da Nang, and Ho Chi Minh City stays the same every month; only the other country may shift if it uses DST, such as the UK, Germany, or the United States.

Vietnam Country Details

Vietnam is a Southeast Asian country in Asia with its capital at Hanoi, the political center in the north and a major hub for government, education, and manufacturing administration. The country has a population of 95,540,395, making it one of the most populous nations in the region and an important market for trade, technology services, textiles, electronics assembly, and tourism.

Vietnam covers 329,560 km², extending along the South China Sea with major urban and economic centers including Hanoi in the north and Ho Chi Minh City in the south. This long geographic shape makes a single national time zone notable, because despite the distance between major cities, businesses, airlines, rail operators, and government offices all coordinate on the same ICT clock.

The official currency is the Vietnamese dong (VND), which is used for retail payments, salaries, hotel bookings, domestic transport, and most local business transactions. International travelers and import-export companies often monitor both local banking hours and the ICT time zone when coordinating payments, invoice deadlines, and customs processing.

Vietnam’s listed languages here are vi, en, fr, zh, km, corresponding to Vietnamese, English, French, Chinese, and Khmer. Vietnamese is the dominant national language, while English is widely used in tourism, outsourcing, technology, and international business, especially in Hanoi and Ho Chi Minh City where foreign firms, factories, and service providers often schedule calls with partners across Asia, Europe, and North America.

The international dialing code for Vietnam is +84. If you are calling a hotel in Hanoi, a factory in Bac Ninh, or a business contact in Ho Chi Minh City from abroad, you start with +84 followed by the local number, and it is wise to check ICT first so you do not place a call during nighttime hours.

Daylight Saving Time in Vietnam

Vietnam does not currently observe daylight saving time, so clocks do not move forward in spring or backward in autumn. The entire country remains on ICT (UTC+7) throughout the year, including Hanoi, Ho Chi Minh City, Da Nang, Can Tho, and Hai Phong.

There are no regional DST differences within Vietnam because the country uses one national time standard. That means there is no situation like in Australia, where some states change clocks and others do not, and no seasonal split between northern and southern areas.

In practical terms, Vietnam’s time is stable while many trading partners change seasonally. For example, Vietnam stays 7 hours ahead of UTC all year, but its difference from London is 7 hours during GMT and 6 hours during British Summer Time, while its difference from New York is 12 hours during Eastern Standard Time and 11 hours during Eastern Daylight Time. Vietnam has not adopted any recent nationwide DST policy changes, and there is no current clock-change schedule to track.

Frequently Asked Questions

how many time zones does Vietnam have?

Vietnam has one official time zone for the entire country: Indochina Time (ICT), UTC+7. This applies nationwide, including Hanoi, Ho Chi Minh City, Da Nang, and all provinces, which makes national scheduling simpler than in countries with multiple time zones.

does Vietnam use daylight saving time?

No, Vietnam does not use daylight saving time. The country stays on UTC+7 all year, so there are no spring or autumn clock changes to account for when planning meetings, flights, or international calls.

what is the time difference between Vietnam and UTC?

Vietnam is 7 hours ahead of UTC, written as UTC+7. For example, when it is 12:00 noon UTC, it is 7:00 PM in Vietnam, and when it is 9:00 AM in Hanoi, it is 2:00 AM UTC.

what currency does Vietnam use?

Vietnam uses the Vietnamese dong, abbreviated VND. The dong is the standard currency for everyday purchases, domestic travel, hotel payments, local payroll, and most in-country commercial transactions.

what is the dialing code for Vietnam?

The international dialing code for Vietnam is +84. If you are calling Vietnam from another country, you enter +84 before the local number, which is important for reaching businesses, government offices, and hotels in cities such as Hanoi and Ho Chi Minh City.

is Hanoi in a different time zone from Ho Chi Minh City?

No, Hanoi and Ho Chi Minh City use the same time zone, ICT (UTC+7). Even though the cities are far apart geographically and serve different economic roles—Hanoi as the capital and Ho Chi Minh City as the main commercial center—the local time is identical in both places year-round.

what time is Vietnam compared with London or New York?

Vietnam is 7 hours ahead of London during GMT and 6 hours ahead during British Summer Time. Compared with New York, Vietnam is 12 hours ahead during Eastern Standard Time and 11 hours ahead during Eastern Daylight Time, so a 9:00 AM meeting in Vietnam usually falls late evening or the previous night in the eastern United States.
