"I like Fridays."
Translation:Eu gosto de sextas-feiras.
I'm gonna take a stab at this, but I'm not sure if I'm right. I believe that "Fridays" can be translated as either "sextas-feiras" or "as sextas-feiras" because the "as" is optional.
So it's either "Eu gosto de sextas-feiras" or "Eu gosto das sextas-fieras" because de + as = das
