Cultural Tip
In Brazil the possessive *seu* is preferred when speaking informally, so you’ll hear "Como vai seu dia?" more often. In Portugal, *teu* is the natural choice with *tu*. Also, the verb *ir* (vai) is a colloquial shortcut for "como está"; both are correct, but "Como está o seu dia?" sounds slightly more formal.
