Changes

All dates, unless otherwise noted, are the Japanese equivalent (the lunar calendar).  However, the Western date will also be generally listed for events taking place between Commodore Perry's arrival in Japan in 1853 until the Japanese calendar was changed to the Western Gregorian calendar in 1873, or in the years before this if it is pertinent to the article in question.  It will also be used for events prior to this when applicable, namely when Westerners were involved in the events of Japanese history during the Sengoku and early Edo period.  When the Western date is also applicable, it will be noted in various ways.
