Vasant Panchami or the beginning of the spring season is on the 5th day of the waxing moon of Magh i.e. 12 February 2016 and is celebrated in the Northern part of India.
The colour yellow is associated with the day, be it clothes or rice coloured with saffron.
Also the day for worshipping Saraswati in some parts of the country e.g. Bengal. And in days past the day for a festival in honour of Kamadeva aka the God of Love, though the celebration shifted with time from April to the beginning of spring and is no longer celebrated.
A lot of people don’t know, but today at Madana Trayodashi is a day dedicated to Kamadeva, the God of desire and love, son of Vishnu and Lakshmi (yes They have children) it was a great festival in Ancient India, one of the traditions that unfortunately lost, texts such as the Nilmata Purana describe the festival, which takes place in spring in the northern hemisphere. He is very handsome, being a beacon of beauty, is married to Daksha’s daughter Rati, capricorn is His symbol, sugar cane is His bow, flowers are His arrows, drones are His bowstring . Vasanta, the god of spring, is his general, while beautiful women are his army. So may Kamadeva fill your life with love and desire…
