Hiero day began as a day of celebration from fans on September 3rd (9/3), a nod to 93 ‘til Infinity, to listen to and appreciate Hieroglyphics’ music. Following suit, the collective responded to the fans with HIERO DAY! 2012 marked the first year of what now has become an annual celebration showcasing a plethora of culture, talent, and a variety of the best local food and crafts available in the greater Bay Area.

Hiero Day plays an integral role in the Oakland music festival culture which exists in the city today. It is recognized for fostering a unifying atmosphere while maintaining a commitment to groundbreaking music and community development.
