Esala Full Moon Poya in Kandy/Kataragama/Nationwide
Esala poya, in July or August, commemorates the Buddha's first sermon, his conception and renunciation, and the arrival of the Sacred Tooth Relic in Sri Lanka. It also marks the start of Vas, the monks' three-month rains retreat. Nationwide, it is observed with white clothing, temple sermons, and dansal stalls, while Kandy and Kataragama each stage their own major Esala peraheras.
Esala, the full moon month of July or August, carries more layered significance in Sri Lankan Buddhist tradition than perhaps any other poya, tying together the conception of the Buddha in his mother's womb, his great renunciation of royal life, his first sermon to five ascetics at the Deer Park near Benares, and the arrival of the Sacred Tooth Relic in Sri Lanka centuries later.
