Loy Krathong and Yi Peng: Traditions, Lunar Calendar, and Festival Guide

Every autumn, Thailand hosts two of Southeast Asia's most visually captivating cultural celebrations: Loy Krathong and the Northern Lanna festival of Yi Peng.

While often celebrated concurrently, they represent distinct cultural legacies unified under the full moon of the traditional Thai lunar calendar.

Understanding the Differences

• Loy Krathong (Nationwide): Floating floral baskets with candles onto rivers and waterways to express reverence to the water goddess (Phra Mae Khongkha).
• Yi Peng (Lanna / Northern Thailand): Releasing sky lanterns (khom loy) into the night sky to symbolize shedding past misfortunes.

Festival Dates and the Lunar Cycle

Festival dates are determined strictly by the 12th full moon of the traditional Thai lunar calendar, which typically falls in November. Celebrations generally span two to three days.

Prime Celebration Hubs in Chiang Mai:

• Nawarat Bridge & River Ping: The primary public gathering point for floating krathongs and admiring river reflections.
• Wat Phan Tao & Wat Chedi Luang: Serene candlelit monastery ceremonies and monk chanting.
• Tha Phae Gate: Official festival parades, traditional Lanna musical performances, and cultural exhibitions.

Environmental Stewardship

Always choose organic krathongs constructed from banana tree trunks, fresh leaves, and natural flowers. Synthetic foam materials are strictly prohibited.
