Let's make this birthday one to remember.

38 years old (Born on October 19, 1986)

Happy Birthday, Zachary Barnett! Hope today truly is the "Best Day of Your Life"—though topping your breakout hit might be tough. You've given us countless reasons to sing along loudly (and off-key) in our cars, showers, and karaoke nights. Thanks for making every day feel like an anthem-worthy adventure!

From rocking stages worldwide with American Authors to inspiring fans everywhere through your debut album "Oh, What a Life," you've certainly set the bar high. May this year bring you even more unforgettable moments and chart-topping successes—because let's face it: you're pretty great at turning life's stories into timeless hits!
