fare un periodo di tempo + che

Today's "Word of the Day" (#PdG)

Today’s Parola del Giorno is the expression fare un periodo di tempo + che, which means to be a period of time since something happened/took place. 

This period of time can be days, weeks, years, and so on (see the example below).

This expression is often used with the adverb oggi (today) to describe the duration of some event in relation to the moment in which one is speaking of it, as in our example below:

Oggi fanno quindici anni che ci siamo lasciati quindi puoi immaginare la mia sorpresa quando l’ho incontrata in metro!

It has been 15 years today since we broke up, therefore you can imagine my surprise when I ran into her on the metro!
