Awareness days are designated dates that highlight important causes, issues, or fields of interest, aiming to educate the public, promote action, and foster global or community engagement. They matter because they draw attention to topics that might otherwise be overlooked, encouraging dialogue, support, and positive change across various sectors of society.

On April 15, two awareness days are observed. World Art Day: an international celebration of the fine arts declared by the International Association of Art to promote awareness of creative activity worldwide.
