According to this "on this day in history site" (http://www.scopesys.com/anyday) the launch date of Voyager 2 was 20 September 1977.

According to Wikipedia (http://en.wikipedia.org/wiki/Voyager_2) it was 20 August 1977

Which one is correct?

August 20th is correct. The site you mentioned lists it also under August 20th :lol:

Maybe someone saw the list "Voyager 1 September 5th, Voyager 2 August 20th" and though that there must have been a mistake.
I remember how they always emphasized in the news those days that and why Voyager 2 was launched first.

Voyager 2 was launched first as it was on a slower trajectory to get it to the other planets compared with Voyager 1
