"I am going to the boys' tonight."
Translation:Vado dai ragazzi stasera.
Yes, it is called the "present progressive" tense, for an action happening currently, as in "I am going home now." However, it is also used to imply the future, as in:" I am going to call you tomorrow." (Often used with an adverb of time indicating the future, such as "next week".) It is equivalent to I will call you.... (or: I'll call you...)
