In the Mayan calendar there were 20 days (called Kins) in a Uinal, 18 Uinals in a Tun, 20 tuns in a Katan and 20 Katans in a Baktun. We write our dates in the order day, month and then year, The Maya write their dates in reverse order giving the baktun, katun, tun, uinal then kin. The Mayan date 13-20-7-16-3 corresponds to 1-1-2000. Write a program which converts between the Mayan calendar and our own.
