904 Day 2026: How Jacksonville Celebrates September 4

904 Day is Friday, September 4, 2026. It is Jacksonville's unofficial city holiday, named for the area code, and it comes with pop-up events, local business deals, and enough Duval chants to carry across the river.

• When: Friday, September 4, 2026
• Where: Citywide
• Cost: Mostly free, varies by event

What to expect

Breweries, restaurants, and shops run 904 specials, and community groups host block parties and markets. Event lists firm up in the final weeks of August, so check Visit Jacksonville and local social feeds as the day gets close.

How to celebrate

Spend money at a local business, wear something Duval, and say the area code out loud more times than is strictly necessary. That covers the core requirements. If you want to rep the city year-round, our Jacksonville sticker collection exists for exactly this occasion.
