## National year of mathematics and delayed monsoon

But why a year on the Christian calendar? That calendar embodies the European ignorance of elementary arithmetic and simple fractions (hence their persistent inability to determine Easter correctly until the Gregorian calendar reform of 1582 when they got the length of the year from Indian books). Click the image for the text version. This newspaper has a circulation of 40 million.

Even so, the Gregorian calendar retains the unscientifc chaos about months. This is a disaster for Indian agriculture. (More details of the monsoon mess in my book *Cultural Foundations of Mathematics*, or an early preliminary article at http://www.indianscience.org/essays/t_es_raju_monsoon.shtml.)
