"Vietnamese Women's Day" or "Vietnam Women's Day"?

[Hieupt]

Hi all,

Today is 20-Oct, is a special day for women in Vietnam. I think it should be named "Vietnamese Women's Day" but there is another option, that's "Vietnam Women's Day". Which one is correct in term of grammar? Or Both?

Anyway, Happy "Vietnamese Women's Day"!

Cheers,
Hieu.
