Accent in numerals

[Vibovit]

According to the dictionaries, in number names between 12-20 (do they have any name as a group, by the way?), the emphasis should be put on the last syllabe; "-teen".

Basically, you say: "thirTEEN", "fourTEEN", and so on.

But is it a fixed rule - or does it depend on the context?

I mean, whenever the number is followed by another duodecimal, one can hear some shift in the accent (or such is at least my impression).

F.e. amounts of money: "FOURteen ninety five, please"

Or dates: "it began in NINEteen thirty nine"

Thanks in advance for some explanation :)

I would say, it depends on the context.

The war began in NINEteen thirty nine, not in EIGHTeen thirty nine.

Or

The war began in nineteen thirty THREE, not in nineteen thirty FOUR.

Or

I couldn't hear what you said. ThirTEEN or thirtY?

When there is no need to avoid misunderstandings, I would stick to the rule you have mentioned above.
