Asalha Puja
In its own language: อาสาฬหบูชา
A Theravada festival marking the Buddha's first sermon and the monastic order

Asalha Puja is a major Theravada Buddhist festival observed on the full moon of the Asadha lunar month, usually in July. Kept across Southeast Asia and Sri Lanka, devotees gather at temples to give offerings, listen to sermons, and commemorate the first teaching of the Buddha.
When is Asalha Puja kept?
Asalha Puja is kept every year on the full moon day of the lunar month of Asadha, usually in July.
Asalha Puja, also known as Dhamma Day, is one of the most sacred holidays in Theravada Buddhism. Celebrated on the full moon of the lunar month of Asadha, it honours the moment the Buddha delivered his very first sermon to five former associates. This occasion marks the initial turning of the wheel of teaching and the founding of the first monastic order.
The first sermon
According to Buddhist tradition, the Buddha gave his first formal discourse in the Deer Park at Sarnath after attaining enlightenment. He shared the core doctrine that defines Buddhism, structured around the Four Noble Truths: the reality of suffering, its origin in craving, the state of cessation, and the Noble Eightfold Path leading to nirvana. This moment is described as setting into motion the wheel of dhamma, forming the foundation for all later Buddhist schools and teachings.
Birth of the sangha
The gathering at the Deer Park did more than reveal new spiritual insights. During the discourse, one of the five listeners grasped the meaning of the teaching and asked to become a disciple. By welcoming him, the Buddha established the first Buddhist monastic community. Because of this event, the festival commemorates not only the dhamma, but also the emergence of the monastic sangha, completing the sacred bond between teacher, doctrine, and disciples.
Temple observances
Devotees mark the holy day by visiting their local temples to present gifts, give alms, and hear monastic members recite sermons on the first discourse. Monks and lay followers may also perform evening candlelit walks around shrine grounds. In Thailand, the festival immediately precedes the start of the three-month rains retreat, known locally as Wan Khao Phansa. Meanwhile, worshippers in Indonesia gather at ancient monuments like Borobudur and Mendut in Central Java.
How Asalha Puja is kept
Lay followers and monks gather at Buddhist temples to mark the holiday together. Devotees present offerings and donations to the monastic community, listen to readings and sermons detailing the Buddha's first discourse, and participate in circumambulation walks around temple shrines. In regions like Central Java, large ceremonies take place at historic stone temples such as Borobudur and Mendut, while in Thailand and other nations, celebrations lead directly into the monastic rains retreat.
When and where
The festival falls annually on the full moon of the lunar month of Asadha, which typically corresponds to July on the solar calendar. The exact date shifts each year according to the lunar cycle.
The holiday is observed across countries with Theravada Buddhist populations, including Thailand, Sri Lanka, Myanmar, Cambodia, Laos, and Indonesia. In Indonesia, major celebrations take place at Borobudur and Mendut temples in Central Java.
What Asalha Puja means
The observance honours the first turning of the wheel of dhamma, representing the delivery of the Four Noble Truths and the path toward liberation from suffering. It also celebrates the founding of the monastic community, marking the moment when the Buddha's teachings were first understood, accepted, and transmitted to disciples.
