Time difference in Vietnam
Between Vietnam and England the time difference is 5 hours.
The time difference and its effects will be felt more by going to Vietnam from Europe.
Vietnam is on the same time zone as Cambodia and Laos.
To better manage the jet lag I recommend a night flight, it will allow you to sleep in the plane with an arrival in the morning on Hanoi or Ho Chi Minh.
On arrival, plan a day rich in activities and meeting to forget fatigue.
If the delay is too strong then, give yourself a mini nap of 30 to 45 minutes maximum without forgetting the alarm clock.
In the early evening around 7 p.m. direction the restaurant and then one night around 8.30 p.m. to take the rhythm of Vietnam. Don’t go to bed around midnight.
