An awareness day is like a birthday party for a special cause or topic. Just like how we celebrate our birthdays to remind us of how special we are and how much we have grown, we celebrate awareness days to remind us of important things that need our attention.
For example, World Autism Awareness Day is a day when people all over the world talk about what it's like to have autism or care for someone with autism. We learn about what autism is, what it feels like to be autistic, and how we can support people with autism.
Awareness days help us learn about issues that we may not have known about before. They help us become more aware, understanding, and respectful of people who are different from us. It's like taking a big group selfie with everyone who cares about the same thing and reminding each other how important it is to care for each other.
