Some of the most popular national awareness days include World AIDS Day, World Cancer Day, National Donor Day, American Diabetes Alert Day and International Walk to School Day. World Health Day, World Meningitis Day, World No Tobacco Day and Sexual Assault Awareness Day of Action are also popular.
Some awareness days are largely orchestrated by a single organization, such as Advocates for Youth's promotion of National Youth HIV & AIDS Awareness Day. World Suicide Prevention Day is sponsored by the International Association for Suicide Prevention. Organizations may change the theme of the day each year. Many offer free or low-cost materials like pamphlets and posters for educators and other community leaders to help facilitate events on a local level. While most awareness days are inspired by serious problems and health concerns, some, such as Single Awareness Day, are for fun.
National awareness days are celebrated with music, contests, volunteer-a-thons and other events. Some events are promoted online via Twitter hashtags, Facebook media shares and memes. Single daily observances, such as National Days of Mourning, are declared by the president. President Gerald Ford's death on Dec. 28, 2006 is one such example. National awareness months, such as Fireworks Safety Month, Childhood Cancer Awareness Month and Domestic Violence Awareness Month, are also widely celebrated.
