On January 1, 1873, Japan adopted the Gregorian calendar, the internationally accepted civil calendar. Nevertheless, the traditional era calendar scheme is commonly used in Japan. The Japanese calendar identifies a year by the combination of the Japanese era name (nengō) and an identification number in ascending order.
