Uposatha Calendar

The Uposatha Calendar has been meticulously crafted to serve as a comprehensive resource for the recitation of Patimokkha twice a month, while also catering to the broader needs of practitioners on both Mahamongkut Uposatha days and general Thai Uposatha days. With utmost precision, this calendar emphasizes the number of new moon and full moon Uposatha days within each of the three seasons. Furthermore, it provides clear indications as to whether these days fall on the 14th or 15th day of the Uposatha cycle.

An Uposatha day is a sacred Buddhist observance that has been practiced since the time of the Buddha (600 BCE) and still continues being kept by Buddhist practitioners today. The Buddha himself taught that the Uposatha day is a time for purifying the mind from defilement, through practices such as observing the Eight Precepts and engaging in meditation. These practices lead to inner calm and joy, allowing individuals to deepen their spiritual connection.
