Full Moon Day of Waso is observed annually on the full moon of the fourth Burmese month, typically in July or August, primarily in Myanmar. This sacred day commemorates Lord Buddha's first sermon and marks the beginning of Buddhist Lent. On this day, many Buddhists gather to offer flowers and new robes to monks, while also abstaining from certain indulgences such as meat, alcohol, and smoking. Participants may engage in meditation and attend special gatherings at temples. The day emphasizes spiritual and community engagement rather than commercial activities, with local Buddhist organizations often hosting events and Dharma talks. Observers are encouraged to learn about Buddhist traditions and practice mindfulness.
