Poya
From BiblePortal Wikipedia
Poya [1]
the day on which the moon changes, which is held sacred among the Buddhists. They reckoned four poya days in each month.
1. The day of the new moon.
2. The eighth day from the time of the new moon.
3. The day of the full moon.
4. The eighth day from the time of the full moon. It is said by Prof. H. Wilson that the days of the full and the new moon are sacred with all sects of the Hindus; but according to the institutes of Manu the sacred books are not to be read upon these days.
