This program computes the local date and time of aphelion and perihelion of the Earth for any given Gregorian year from 1600 to 2200.  To obtain the local times, the ΔT (Delta T) estimate is applied to the time zone adjustment , according to the NASA polynomials for Delta T.


Year (1600 to 2200) =            Local Time = UT  :
