"He swims every Wednesday and Saturday."
Translation:Er schwimmt jeden Mittwoch und Samstag.
my first thought to this sentence was 'is it every wednesday AND every Saturday?, or just 'every wednesday and THIS PARTICULAR saturday'. so if the sentence implies every wednesday AND every saturday then i would assume you need an every for both of the days (No assumptions necessary for the implications).
I entered 'Er schwimmt jeden Mittwoch und jeden Samstag' But it got marked wrong :( hence why i came into here to find out if saturday should have an every as well.
I blame english for this as it is ambiguous if Saturday is every Saturday or just this particular Saturday. now i just don't know if the German equivalent is doing the same thing or not????
