National Day of the Gong is observed worldwide every June 21, celebrating the unique history and cultural significance of the gong, a percussion instrument that originated in East and Southeast Asia. The holiday was launched in 2017 by Gong to Go, a project aimed at educating the public about the gong's transformational power. Celebrations include reading about the history of gongs, watching gong performances, meditating with gongs, and learning to play the instrument. The gong itself comes in various types, such as suspended gongs, bossed gongs, and bowl gongs, each producing distinct sounds and used in different contexts, from religious rituals to modern performances. Participants are encouraged to share their experiences on social media using the hashtags #NationalDayOfTheGong and #NationalGongDay.
