Vasanta Purnima is the full moon day that falls in the middle of the spring season in India. This auspicious day holds immense significance as it coincides with Holi, the festival of colors. The tradition of playing Holi with colors is believed to have originated during the era of Lord Krishna. It is considered the birth anniversary of Goddess Lakshmi, the goddess of wealth and prosperity, and Saint Chaitanya Mahaprabhu, a revered Vaishnavite saint and proponent of Bhakti yoga. The Hindu calendar follows a lunar cycle and gradually shifts over thousands of years due to astronomical precession. Unlike fixed seasonal festivals in the Gregorian calendar, Hindu festivals follow a lunar calendar and gradually shift over Thousands of Years due to Astronomical Precession. The spring season generally begins on February 19 and lasts until April 19. All Hindu festivals falling within this period are often associated with Vasanta Ritu. For instance, Vasanta Panchami sometimes occurs before February 19, before spring officially begins.
