Short answer: the entry date is the first day your eVisa is valid, and the whole validity period (up to 90 days) counts from that date. You cannot enter before it. You can enter later, but the days in between are lost. Put the date you land in Vietnam, or one or two days earlier as a buffer.
How it works in practice
- Entry date 15 June, you land on 10 June: you won't be allowed to board or enter. This is the costly mistake.
- Entry date 15 June, you land on 18 June: fine. The visa still ends on the same date, so you have three days less.
- Entry date 13 June, you land on 15 June: fine. A small buffer covers a rebooked flight.
Watch the time difference
Use your arrival date in Vietnam, not your departure date. Overnight flights from Europe, North America or Australia often arrive the next calendar day. Flights that cross the date line can arrive "earlier" than you think. Check the arrival date on your ticket.
Choosing the length
The government fee is the same whether you ask for 15 or 90 days. Choose enough days to cover your whole trip plus a few spare, because an eVisa can't be extended inside Vietnam. See can I extend my eVisa.
Dates changed after approval?
An issued eVisa can't be changed. If your new arrival is later and still inside the validity period, you can simply use it. If you now arrive earlier than the entry date, you need a new eVisa.

Can I enter before my eVisa entry date?
No. The airline or immigration will refuse you.
Can I enter after it?
Yes, within the validity period, but you lose the unused days at the start.
Does the exit date matter?
You must leave by the expiry date. Overstaying leads to a fine and a record.
