No because "night" is used like evening too. A night out (meaning an evening out) is not the same as spending the night somewhere. Evening = sera = (early) night...as in, before midnight. So, night can be synonymous with sera or notte. We use night two different ways. As a result, u can translate sera as evening or night. Notte, however, can only be translated as night.
I can see your line of thoughts.
since it is written sera meaning night (singular), the translation means Friday (all day, not a specific part of the day) and saturday evening (not during the day, just the evening).
Had it been Venerdì e sabato sere it would have been Friday and Saturday evenings/nights (indication only evening part of the day, but both days)
The first way is as it appears in the duolingo item (though it's ambiguous). You could also say "venerdí sera e sabato sera" or "venerdí e sabato sere" (I think) or "le sere di venerdí e sabato". Depending on context, it could even be "durante la sera (questo/quello) venerdí e sabato". Also notte is night as in late night and sera is like "night" as in evening...sort of like a night out (before midnight). :) In boca al lupo.
Just read the libretto of Aida in Italian. "Di" (not " giorno") with the accent throughout for "day", so SanneTofte is right. And "Aida" is not distant past, just the 19th century. In sum, "lunedi", "martedi" ... "venerdi" are compound words, the second part being "day". What is accented is not just the last vowel but actually the "i" in "di". (Sorry, I do not have the accent on my keyboard, at least not for "i"). "Sabato" and "domenica" do not have "di" in them, hence no accent.
Americans in the southern states use "evening" to mean what the rest of the country calls "afternoon"., so the Italian for "good afternoon" is not really so strange. Southerners must have some historical reason for saying it that way (Latin, maybe?), one which is probably also implied in the Italian.
thanks for all the discussion. I used sere instead of sera. I was confused when I was corrected saying "You used the plural 'sere' here, instead of the singular 'sera'. but it had the meaning "Friday and Saturday nights" which is plural. Evening makes it easier to understand.
e/ed = and The rule for e vs ed is very similar to the English rule for a vs an.
They are two entirely different words.
