Title: Uposatha Observance Days
Uposatha Observance Days
See also <a href=“uposatha-calendar_en.html”>This year's calendar of uposatha days</a>
Uposatha days are times of renewed dedication to Dhamma practice, observed by lay followers and monastics throughout the world of Theravada Buddhism.
For monastics, these are often days of more intensive reflection and meditation. In many monasteries physical labor (construction projects, repairs, etc.) is curtailed. On New Moon and Full Moon days the fortnightly confession and recitation of the Bhikkhu Patimokkha (monastic rules of conduct) takes place.
Lay people observe the Eight Precepts on Uposatha days, as a support for meditation practice and as a way to re-energize commitment to the Dhamma. Whenever possible, lay people use these days as an opportunity to visit the local monastery, in order to make special offerings to the Sangha, to listen to Dhamma, and to practice meditation with Dhamma companions late into the night. For those not closely affiliated with a local monastery, it can simply be an opportunity to step up one's efforts in meditation, while drawing on the invisible support of millions of other practicing Buddhists around the world.
The calendar of Uposatha days is calculated using a complex traditional formula that is loosely based on the lunar calendar, with the result that the dates do not always coincide with the actual astronomical dates. To further complicate matters, each sect within Theravada Buddhism tends to follow a slightly different calendar.
Several full-moon Uposatha days hold special significance in the Buddhist calendar:
This day, sometimes called “Sangha Day,” commemorates the spontaneous assembly of 1,250 arahants in the Buddha's presence. One thousand of the gathered monks had previously achieved Awakening upon hearing the Buddha's delivery of the Fire Sermon; the remaining 250 were followers of the elder monks Ven. Moggallana and Ven. Sariputta. To mark this auspicious gathering, the Buddha delivered the Ovada-Patimokkha Gatha, a summary of the main points of the Dhamma, which the Buddha gave to the assembly before sending them out to proclaim the doctrine. [Suggested reading: “Dhamma for Everyone” by Ajaan Lee.]
This day, sometimes called “Dhamma Day,” commemorates the Buddha's first discourse, which he gave to the group of five monks with whom he had practiced in the forest for many years. Upon hearing this discourse, one of the monks ( Ven. Kondañña) gained his first glimpse of Nibbana, thus giving birth to the Noble Sangha. The annual Rains retreat (vassa) begins the following day.
This day marks the end of the Rains retreat (vassa). In the following month, the kathina ceremony is held, during which the laity gather to make formal offerings of robe cloth and other requisites to the Sangha.
At the end of one rains retreat (vassa), the Buddha was so pleased with the progress of the assembled monks that he encouraged them to extend their retreat for yet another month. On the full-moon day marking the end of that fourth month of retreat, he presented his instructions on mindfulness of breathing (anapanasati), which may be found in the Anapanasati Sutta (MN 118) — The Discourse on Mindfulness of Breathing.
