Vishu (Malayalam:വിഷു) is a festival held in the state of Kerala in South India (and malayali’s in adjoining areas ofKarnataka and Tamil Nadu). Similar festivals are celebrated in Punjab and Assam, in India, around the first day in theMalayalam Month of Medam (April – May). Vishu follows the sidereal vernal equinox and generally falls on April 14 of the Gregorian year. This occasion signifies the Sun’s transit to the zodiac – Mesha Raasi (first zodiac sign) as per Indian astrological calculations. Vishu is also considered as the harvest festival of Kerala and thus the importance of this day to all Malayalees. In Assam this day is called Bihu, in Punjab Baisakhi (originally Vaishakhi) and in Tamil Nadu Tamil Puthandu or Vishu punyakalam.The word “Vishu” in Sanskrit means “equal”. Therefore Vishu is more probably denoting one of the equinox days.
