Awareness days are designated dates focused on highlighting specific causes, issues, or groups to educate the public, foster understanding, and inspire action. They play a crucial role in bringing global attention to important topics, promoting advocacy, and encouraging societal change by uniting individuals and organizations around shared goals.

On April 2, two awareness days are observed.
