The time of the Waxing moon is called the Shukla Paksha. It is the period from New Moon (Amavasya) to the Full Moon (Purnima) when the Moon brightens up. Whereas the time when the Moon fades its form is called Krishna Paksha. This period starts from Full Moon and ends at New Moon. Each of these periods comprises 15 days which are known as Shukla Paksha Tithi and Krishna Paksha Tithi respectively. Moreover, the dates such as Purnima Tithi and Amavsya Tithi of Hindu Panchang are considered as the most significant Tithis in Hindu traditions.
