fui a la semana pasada o fui a la fin de semana pasada

Question

I went last week, or I went last weekend ! Is the sentence correct? Thanks in advance.

Answer 1

You don't say "a la semana pasada", but "la semana pasada".

Answer 2

It's pretty good.
But weekend is masculine so you say: el fin de semana pasado

In fact the translation is ok but it is too ackward.
I would say: "Creo que fui la semana pasada o el fin de semana pasado, no me acuerdo bien.."
That means: "I think I went last week or last weekend, I dont remember well..."
