Purnima

Pūrṇimā (Sanskrit: पूर्णिमा) is the word for full moon in Sanskrit. The day of Purnima is the day (Tithi ) in each month when the full moon occurs, and marks the division in each month between the two lunar fortnights (paksha), and the Moon is aligned exactly in a straight line, called a syzygy, with the Sun and Earth. Full moon is considered the third of the four primary phases of the Moon; the other three phases are new moon, first quarter moon, and third quarter moon. The full moon shows 100% illumination, causes high tides, and can concur with lunar eclipses.^[1]

The following festivals occur on the purnima. The Manava Purana (one of the Upapuranas) contains a list of the festivals that fall on the full moon.
