Yi Peng Festival 2026

Loy Krathong coincides with the Lanna (northern Thai) festival known as Yi Peng. Yi means ‘two’ and peng means a ‘full moon day’. Yi Peng refers to the full moon day in the second month according to the Lanna lunar calendar (the twelfth month of the Thai lunar calendar). The festival is meant as a time to make merit.

Swarms of sky lanterns (Thai: โคมลอย; RTGS: khom loi), literally: ‘floating lanterns’, are launched into the air. Khom loi are made from a thin fabric, such as rice paper, stretched over a bamboo or wire frame, to which a candle or fuel cell is attached. When the fuel cell is lit, the resulting hot air is trapped inside the lantern and creates enough lift for the khom loi to float into the sky.
