Wear Blue Day

Celebrated on 06/19/2026

Quick Fact

Wear Blue Day is observed on the first Friday of March each year as part of National Colorectal Cancer Awareness Month. The color blue symbolizes the importance of regular colon cancer screenings, which can detect the disease early when it's most treatable.

Origins and Establishment of Wear Blue Day

Wear Blue Day was established by the Colorectal Cancer Alliance in 2009 to raise awareness for colorectal cancer, the second leading cause of cancer deaths in the United States. The day was created to encourage people to wear blue and talk about the importance of screening, as colorectal cancer is highly preventable with regular colonoscopies.

Evolution and Modern Commemoration

Since its inception, Wear Blue Day has grown into a nationwide movement, with landmarks lighting up in blue, social media campaigns using #WearBlueDay, and community events promoting screening. Today, it is celebrated on the first Friday of March, and participants wear blue clothing, share facts, and encourage loved ones to schedule screenings. The day also highlights the stories of survivors and those lost to the disease.
