Keeping Time in Vietnam: A Guide to the 24-Hour Clock

While traveling to a new country, navigating cultural nuances like currency and language is expected. But what about something as seemingly universal as telling time? Vietnam, a land steeped in rich history and tradition, presents a subtle yet significant difference in its timekeeping: the ubiquitous use of the 24-hour clock.

Forget the AM and PM distinctions commonly found in many parts of the world. In Vietnam, time is expressed in a continuous flow from midnight to midnight using the 24-hour system. This means that 1:00 in the afternoon is not written as 1:00 PM, but rather as 13:00, or 13h, using the international standard.

This practice permeates all aspects of Vietnamese life, from train schedules and business appointments to casual conversations about dinner plans. Whether you’re glancing at a digital clock, checking a handwritten note, or simply asking a local for the time, be prepared to interpret the hour using the 24-hour format.

Here’s a quick breakdown:

• Separators: Both a colon (:) and the letter ‘h’ are acceptable separators between the hours and minutes. For example, 7:30 AM would be written as 07:30 or 07h30. Similarly, 8:00 PM becomes 20:00 or 20h.
• Full hours: When expressing a time on the hour, the minutes are often omitted. For instance, 2:00 PM is simply written as 14h.

While the initial adjustment might seem minor, embracing the local timekeeping custom can enhance your travel experience. It reflects a respect for Vietnamese culture and demonstrates your willingness to adapt to local norms. So, ditch the AM and PM and confidently navigate your time in Vietnam with the clarity of the 24-hour clock.
