Malayalam New Year starts on Vishu Day. On this day the Sun transits from Pisces to Aries(the Sun at Zero degree) and in Kerala the Sun will be exactly over the head at noon. So, it can be seen that the Malayalam calendar is the most scientific and its approach is proclaimed by the flowering of Kani Konna ( Casia Fistula). More details on Vishu can be had from earlier posts or a google search. Wish you all a Happy Vishu and Prosperous New Year.
