Hi, the "DIVERTIRE" is used for indicate the pleasure of doing something. it's refers to positive moods. for example: come è andata la festa? (How was the party?) bene, mi sono DIVERTITO molto! "GRADIRE" is certainly few used in italian speaking of every day; is an archaic form. it's used mainly in a specific contest, for example for speak about the food: Ti piace il caffè? prendi una tazza di caffè? (=Do you like Coffee? Do you take a cup of coffee?) si, lo GRADISCO. but in general, the verb more used is "PIACERE" (=to like). ti piace il caffè? si, mi PIACE.

If you want to wish or hope that someone enjoys something (a trip, a moment ecc) you can use the verb GODERE: "Goditi il meritato riposo" (Enjoy this deserved rest) or "Goditi la giornata" (Enjoy your day). It's a sort of invitation to be happy and take advantage for something; is this what you mean?

To enjoy oneself = godersela, divertirsi Enjoy yourself = divertiti Enjoy your day = Buona giornata Enjoy the rest of your day = Buon proseguimento di giornata Enjoy your holiday! Buona vacanza! Enjoy! Divertiti! Goditelo/a!

Ciao! Puoi dire: Abbi una buona giornata, goditi la vacanza o quello che sia. Oppure stai bene e divertiti.

You use ''GRADIRE'' for to express that you like a thing, or you would like a action. Instead, the verb ''DIVERTIRE'' means enjoy amusements, that you are happy because you're living a funny experience with someone or something.
