The Sun enters Zero Degree of the Sidereal Zodiac on 14th. His gross Right Ascension will be Zero and Declination Zero. This is widely celebrated by the wise as Vishu, the Harvest Festival.
An Agri Festival, Vishu marks the end of the blistering heat which characterised Pisces and Aquarius, Meena and Kumbha. There may be moderate rains in Kerala, but will accelerate after Sun transits the 45th Degree of the Zodiac, Edava Pathi, on May 29th.
Happy Vishu in advance !
