Loi Krathong is a Thai festival held on the full moon night of the twelfth lunar month, usually in November, when people float small decorated baskets called krathong on rivers and ponds. The song heard here, built around the repeated phrase loi loi krathong, is the well known festive song sung in schools, parades and community celebrations across Thailand. Its simple, catchy chorus has made it a staple online for festival greetings, cultural lessons and travel videos sharing the atmosphere of the night.
