The Gregorian calendar is obsolete in Summer of Gronk, which doesn't follow the constructs of modern timekeeping. Simply put: While it might be the first week of spring for most of us, Rob Gronkowski's offseason is one long summer vacation.

Earlier this week, the Patriots' playmaking tight end could be seen on a yacht with the ladies, the bros and free-flowing champagne.

The latest sighting puts him in Miami at the Ultra Music Festival, where he got on stage with 3LAU and did a little dancing while sporting a neon tank top (with matching shorts, natch).

#GRONK!!!!!

Your move, Tom Brady -- Gronk doesn't even need water.
