Happy 312 Day! Celebrate the Unique Chicago Culture in Style

March 13, 2023

312 Day is right around the corner, and Chicagoans are already gearing up for the city’s biggest event. Since Goose Island Beer Company initiated the annual tradition on March 12, 2011, the people of Chicago have been proudly celebrating what their hometown has to offer.

Whether it’s your first time hearing about Chicago’s area code-inspired holiday or you’re a true-blue Chicagoan, there’s something you can enjoy on this special day. Here's everything you need to know about this year’s 312 Day festivities.

Where Did “312” Originate?

Back then, the Chicago metropolitan area used 312 as its area code. 312 is one of the original 86 area codes established by AT&T and the Bell System in 1947. However, in 1995, area code 773 was added. Because of this, the existing 312 area code was split into two distinct areas.

In 2009, another area code, 872, was added, and with it, 11-digit dialing was introduced to the Chicago region. Currently, the newest area code is an overlay to 312 and 773.

Overlay refers to multiple area codes serving the same geographic area. Unlike its predecessors, area code 872 was overlaid with the 312 and 773 area codes, which is why it serves every part of town.

What Is 312 Day All About?

One day, in 2011, while eagerly waiting for winter to be over, the folks at Goose Island Beer Company had the brilliant idea to make up a holiday event to enjoy Chicago’s almost-spring weather.

Call it destiny or pure coincidence, but the day they chose was March 12, which they immediately connected with Chicago’s original area code of 312. Thus, the legendary 312 Day was born.

Goose Island President Todd Ahsmann shared this remarkable story with Forbes:

“In the Midwest, we all understand how brutal the winter season can be,” he said. “A small group of us started a made-up holiday as an excuse to get out and enjoy Chicago. Flash forward to the present day; it’s bigger than ever, with a ton of celebrations happening all around Chicago.”

Due to the outpour of support from locals, in 2014, the mayor of Chicago declared March 12 an official city holiday. Today it’s one of the most well-loved and celebrated urban holidays. It encourages Chicagoans to show their love for their hometown by spotlighting everything and anything that makes it special—from culture to food, music, and homegrown talents.

This kind of celebration isn’t unique to Chicago, as other cities like Saint Louis and Milwaukee also have their area code day celebrations. However, Chicagoans’ enthusiastic commitment to 312 Day makes it the country's most extensive city area code-inspired holiday. Not to mention it carries an incredible backstory!

Even though the 312 festivities have spread throughout Chicago, Goose Island remains connected to the holiday. They even leveraged it by promoting their first canned beer product, the 312 Urban Wheat Ale.
