Let's make this birthday one to remember.

51 years old (Born on July 20, 1973)

Happy Birthday, Kronprins Haakon! You're officially one year closer to swapping that crown-in-waiting for the real thing—no pressure though. From gracefully navigating royal events to charming your way across Norway and beyond, you've shown us all how royalty blends perfectly with being effortlessly cool.

Your recent advocacy for environmental awareness proves you're more than just future throne-sitting talent; maybe you could leverage some of that regal authority into finally making "fish-flavored birthday cake" an official Norwegian delicacy? Until then, here's wishing our favorite soon-to-be king another incredible journey around the fjord-filled sun filled with plenty of laughter and adventures!
