Introduction on Buddhist Observation Days
The Observance Days are based on the traditional Buddhist calendar of new, full and quarter moons. During new and full moon days, or Uposatha Days, monks would gather to listen to the recitation of the Patimokkha rules. The weekly observance of the quarter moon is when lay devotees gather in temples to observe the precept and listen to Dhamma discourses.
Below is the list of Buddhist observance days for year 2017 based on the Thai calendar.
LUNAR OBSERVANCE DAYS
These days are regularly devoted to quiet reflection at the monastery.
The dates for the lunar calendar are determined by traditional methods of calculation
and are not always on the same day as the astronomical occurrences.
