About the Japan's adoption of the Gregorian calendar, 1873

The Meiji government replaced the traditional lunisolar calendar with the Gregorian one with only weeks of notice: the 3rd day of the 12th month of Meiji 5 became 1 January 1873. One motive was financial, as it avoided paying officials for a leap month in the old calendar. Japan kept its era names for year numbering.
