The Full Moon Day of Waso is one of the significant holidays celebrated in Myanmar (Burma). This special event commemorates the first sermon delivered by Gautama Buddha and his conception and renunciation. Falling in the Burmese month of Waso (June to July), it signifies the start of the three-month Buddhist lent, a time when monks retreat to their monasteries for intensive meditation.

A fascinating feature of the Full Moon Day of Waso is that it is also believed to be the day Buddha was conceived. Hence, the day holds multiple meanings ethically and culturally for people in Myanmar. Prominent traditional events and rituals take place throughout the country, such as offering alms and 'Waso robes' to Monks. There is also a custom of gifting the 'Waso chinlone' a traditional cane-ball, reflecting the deep-rooted sports culture of the country.

On the Full Moon Day of Waso, the Burmese people also make a special effort to observe the Five Precepts. This day is also associated with the first Buddhist council, held three months after Buddha’s death. People celebrate by visiting pagodas, meditating, and doing meritorious deeds. Moreover, this festival offers a deeper understanding of Myanmar's unique culture and traditions.
