Paush Purnima
Paush Purnima is celebrated during the Magha month of Hindu calendar. The specialty of this day is to take a dip in any holy water body. Some parts of India celebrate Paush Purnima as Shakambhari Purnima.
Kumbh Mela traditionally begins on Paush Purnima and continues until the end of Maha Shivaratri.
