Full Moon Day of Tabaung is a significant public holiday in Myanmar, also known as Burma. This holiday falls on the day of the full moon in the Burmese calendar's third lunar month, Tabaung, which typically aligns with February or March in the Gregorian calendar. Tabaung's full moon is significant for its spiritual and cultural importance to the Burmese people, culminating in a festive day of celebrations and observances.

This holiday is rooted in the Theravada Buddhist traditions prevalent in Myanmar. It commemorates the conclusion of the Buddha's intensive period of spiritual retreat and the delivery of his teachings, known as 'the Ovada Patimokkha'. Common observances during the holiday include making merit, visiting pagodas, participating in meditation retreats, and giving alms to monks. Traditional activities range from public readings of Buddhist scriptures to vibrant pagoda festivals, brimming with music, dance, and theatrical performances.

One of the most notable features of the Full Moon Day of Tabaung is the myriad of pagoda festivals held nationwide. One such notable event is the Shwedagon Pagoda Festival in Yangon, Burma's largest city. During the festivals, Myanmar's pagodas are adorned with colourful decorations, thousands of lights, and worshippers pay homage by offering fruits and flowers. These festivals serve as vast community gatherings, allowing attendees to both honour their Buddhist faith and celebrate Burmese culture, fostering a profound sense of unity and shared cultural heritage.
