Newark Days is a four-day festival held to commemorate the birthday of the City of Newark, California held every year in September. In 2025, we’ll be celebrating Newark’s 70th birthday from September 18-21 with the theme, Celebrating the 70s! 

Newark Days is enjoyed by over 100,000 people every year. The festival is organized by Newark Days Celebration Inc., a 501(c)(3) nonprofit organization that is made up entirely of volunteers. The volunteers of the Newark Days Committee work throughout the year to plan and host all the events.
