National Lei Day is celebrated on November 11 each year, recognizing the significance of the lei, which is a traditional Hawaiian garland made of flowers. The term "lei" has Chinese origins, meaning 'flower bud' or 'thunder,' and it also signifies 'child' or 'string of flowers' in Hawaiian. The celebration emphasizes appreciation for the lei, which is often worn during various cultural events and festivities. The name "Lei" is also associated with Lei Zu, a legendary Chinese empress credited with discovering sericulture and inventing the silk loom. In Hawaii, the lei symbolizes love, friendship, and hospitality, and people often exchange leis as a gesture of goodwill. The observance of National Lei Day highlights the cultural significance of this floral adornment in both Hawaiian and Chinese traditions.
