Japan adopted the Gregorian calendar's way of working out leap years on January 1, 1873, but the months have numbers instead of names. Japan also starts year one with each new reign, but uses reign names not the name an emperor might be best known by in the west. For example, the reign names "Meiji" year 1=1868, "Taisho" 1=1912, "Showa" (Emperor Hirohito) 1=1926, "Heisei" (Emperor Akihito) 1=1989, and so on. The "Western calendar" (西暦, "seireki") using western year numbers, is also widely accepted by civilians and to a lesser extent by government agencies.
