Harmony Day is a special day celebrated on March 21st where people from all over the world come together to celebrate diversity and friendship. On this day, we do fun activities like sharing food, dressing up in traditional clothes, learning dances, telling stories, and making art. But most importantly, Harmony Day is about being kind and understanding to everyone, no matter where they're from. It's a day to show love and respect for all people, no matter their background.
