"Letzte Weihnachten."

Translation: Last Christmas.

[Gildesh]

In this case, Weihnacht is femenine --> so we conjugate letztE, but Weihnachten appears as neutrum (don't know the difference among them), so it should be letztes Weihnacthen right?

[christian]

There's a lot of regional variation when it comes to the word "Weihnachten". Both "letztes Weihnachten" and "letzte Weihnachten" are fine.
