The monks thought, “How many observance days are there?” They told the Buddha. “There are two observance days: the fourteenth and the fifteenth day of the lunar half-month.”

The monks thought, “How many kinds of observance-day procedures are there?” “There are these four kinds: The observance-day procedure that is illegitimate and has an incomplete assembly. The observance-day procedure that is illegitimate but has a complete assembly. The observance-day procedure that is legitimate but has an incomplete assembly. The observance-day procedure that is legitimate and has a complete assembly. The first,

second, and third of these shouldn’t be done; I haven’t allowed such procedures. The fourth should be done; I have allowed such procedures. Therefore, monks, you should train like this: ‘We will do observance-day procedures that are legitimate and have a complete assembly.’”
