Krita in history...
"Azes is now being associated with the creation of the era of 58 BC that was to be known through the centures as the Krita, Malava or Vikramaditya, samvat, era. Possibly the era was also calculated for use in astronomy as the term krita, created, would suggest, but was given status by association with royalty."
