Four major ways have been used to identify years in Japan. One is by reign years, a system used in early history; another is counting from the beginning of a year period, or era, (the ''nengô'' 年号system), which is still the official dating system; the third, now used only marginally in Japan, follows the Chinese 60-year cycle (''kanshi'' 干支 system); and the fourth is the Western, or Christian, calendar. | Four major ways have been used to identify years in Japan.
