You've probably heard of May Day, but have you heard of Lei Day? 🌺 Since 1927, Hawai‘i has celebrated Lei Day on May 1. The colorful celebration honors the art and giving of lei, which is a symbol of aloha. As a symbol of respect and tradition, any lei you receive in Hawai‘i should be left with nature rather than disposed of, after removing any man-made materials like string or ribbon.
