✓ Since ✗ Until

We can never obtain peace in the outer world until we make peace with ourselves.
Non possiamo ottenere la pace nel mondo esterno finché non facciamo pace con noi stessi.   
– Dalai Lama
 ✓ Until last year she was in good health.
✗ *Since* last year she was in good health.
Fino all’anno scorso era in buona salute.
Some Italian learners of English mix up these two words. Until corresponds to fino a or finché non in Italian, while since corresponds to da or da quando.
Some more examples with until:
✓ The identity of the murderer isn’t revealed until the last page. (= fino a)
L’identità dell’assassino non si svela fino all’ultima pagina.
✓ Let’s wait here until it stops. (= finché non)
Aspettiamo qua finché non smette.
Some more examples with since:
✓ Sorry, I’m a bit tired. I’ve been on my feet since six o’clock this morning. (= da)
✓ He’s been depressed since he lost his job. (= da quando)
 JUST A NOTE: notice that the verb after until is affirmative in English, and not negative, like in Italian. See until: ✓ until + AFFIRMATIVE ✗ until + NEGATIVE
