... This paper discuss a polynomial approximation to T for the range of 1620 to 2000 AD published by Jean Meeus and Larry Simons and gives a modified version of this approximation which is much more accurate. ... For this purpose Jean Meeus and Larry Simons published a paper in 2000, which gives a set of polynomial approximation of T for the range of years 1620 to 2000 (Meeus 2000). ... Using these empirical formulae we can calculate the value of T at any instant of the year for the range 1620 to 2000...
