Etymology

Purnima is derived from Sanskrit words purni meaning "full" or "complete" and ma meaning "moon" signifying the full moon.

Description

In the Hindu lunar calendar, each month has 29 or 30 days. The month begins on the next day after Amavasya (new moon) or Purnima (full moon) in the amanta and purnimanta systems respectively. The amanta system is followed majorly in the South India and the purnimanta system in North India. A month consists of two cycles– Shukla Paksha (waning moon) and Krishna Paksha (waxing moon), consisting of 15 days each. Days in each cycle is labeled as a thithi, with each thithi representing the different phases of the moon and repeating twice in a month.

Purnima corresponds to the period when the Moon is aligned with the Sun and the Earth in syzygy. The Earth comes in between the Sun and the Moon, which are aligned at 180 degrees of ecliptic longitude. The full moon shows 100% illumination of the lunar disk as seen from Earth, as the Sun and Moon are on opposite sides of the planet. It causes high tides known as spring tides due to the combined gravitational pull of the Sun and Moon acting along the same line. A full moon can also coincide with a lunar eclipse, which occurs when the Earth passes directly between the Sun and Moon, casting its shadow on the moon's surface.

Notes

The Hindu calendar follows two various systems:Amanta and Purnimanta. As per the amanta tradition, the lunar month ends on the new moon day and as per the purnimanta tradition, it ends on the full moon day. As a consequence, in the amanta tradition, Shukla paksha (waning moon) precedes Krishna paksha (waxing moon) in every lunar month, whereas the reverse happens in purnimānta tradition. Hence, Shukla paksha will always belong to the same month in both traditions, whereas Krishna paksha will always be associated with different but succeeding months in each tradition. The Amanta tradition is officially followed by the Indian national calendar.
