Gupta era

The Gupta era is a historical calendar era that begins from c. 318–319 CE. It was used by the Gupta emperors, as well as their vassals and their successors in present-day northern India and Nepal. It is identical to the Vallabhi era (or Valabhi era), which was used in the Saurashtra region of western India, although regional differences lead to a slightly different calculation for the conversion of Vallabhi era years to Common Era (CE).
