On March 3rd, 3/03, Colorado launched a new state holiday, “Buy Colorado Day”. It aims to elevate the existing 303 Day tradition into a statewide movement to support our local economies.
In addition to March 3rd being “Buy Colorado Day”, the week of March 3rd to 10th will officially be “Buy Colorado Week”.
“303 Day” Becomes “Buy Colorado Day”

“Buy Colorado Day isn’t just another shopping holiday—it’s a movement to transform how we support local business. By uniting Colorado’s most innovative brands with conscious consumers all over the world, we’re creating an economic engine that will drive our state’s commerce for generations.” — Ricardo Baca, Founder of Buy Colorado Day and Grasslands: A Journalism-Minded Agency®
The significance of the former 303 Day, was in honor of the 303 area code, which covers the Denver Metropolitan Area. However, it was one of America’s first area codes and originally covered the entire state of Colorado. The Centennial State now boasts 5 area codes, including 303, 719, 970, 720, and 983.
There are more than 700,000 small businesses in Colorado. Shop local Colorado brands this week and beyond.
