Astrology is an ancient geocentric concept which has absolutely no impact on anyone except via the placebo effect which influences the faithful. The point on ecliptic that is selected as the first point of Aries in Sri Lanka is well within the constellation of Pisces in the observed Sky, not on border with Aries. It happens to be the position of the Sun on the Spring equinox of CE 282 March 21st. The year of King Mahasena's Coronation. This definition has moved New Year by one day on average every 70.56 years on Gregorian Calendar to April 13-14th due to Precession of Equinox. Remember it was 12-13th about 50 years ago. We need a practical definition for the cultural event, not locked into meaningless astrology..
