In Japanese you have to say "this week's Saturday" to specify "this Saturday" rather than any other Saturday. Is that what you're asking?
I guess in Japanese you say "this week's Saturday" instead of "this Saturday"
It's because it's asking about THIS Saturday (which could be the Saturday of this week)
I agree, it was misleading. I think it was referring to "This Saturday" meaning the Saturday of this week.
"This saturday" was considered as "this week's saturday" for the sake of translation. It's sensible but pretty confusing for translations like this.
It's because Duo can be randomly picky about the kanji it allows. In this case, kanji works for every word EXCEPT "曜", which is pretty silly. We just need to keep reporting until they (hopefully) work out these kanji issues.
