National and International Days on May 19

Celebrate Your Elected Officials Day: This day offers a moment to appreciate the public service of elected officials across all levels of government. While the exact origin remains unknown, it’s grown into a way for communities to thank those who represent them—regardless of political affiliation. Recognizing the effort behind reading reports, attending meetings, and responding to constituent concerns, this day aims to build mutual respect between citizens and their leaders.

Hepatitis Testing Day: First observed in 2012, Hepatitis Testing Day was launched by the U.S. Department of Health and Human Services following a national action plan created in 2011. The goal is to raise awareness about viral hepatitis—particularly hepatitis B and C—which often goes undiagnosed. By encouraging testing, the day helps prevent long-term complications like liver damage and cancer. It also supports the broader goals of Hepatitis Awareness Month, observed throughout May.

National Devil’s Food Cake Day: Celebrated each year on May 19, this day honors the decadent, deeply chocolaty cake that became popular in the early 20th century. The name “devil’s food” refers to its rich and bold flavor, contrasting the lightness of angel food cake. One of the first recipes appeared in Sarah Tyson Rorer’s 1902 cookbook, and the cake has been a favorite ever since. It typically uses cocoa, hot water, and sometimes coffee to create its signature taste and texture.

National Mechanical Dry Eye Day: Established in 2020 by Bio-Tissue, this observance raises awareness about mechanical dry eye—a frequently overlooked condition that primarily affects those over 60.

Bio-Tissue, founded in 1997, supports advanced eye treatments and encourages early diagnosis of conditions like this one.

National Roadie Day: First celebrated in 2025, this day honors the behind-the-scenes heroes of the music industry—roadies.

Dorcy worked with legends like Willie Nelson and Johnny Cash, setting a standard for dedication and grit. National Roadie Day celebrates the essential work road crews do to make live performances possible.

Plant Something Day: Initiated in 2012 by the National Initiative for Consumer Horticulture (NICH), this day promotes planting as a way to enrich the environment and daily life.
