Dates in this period can be confusing. Japanese sources use lunar calendar dates and era names, so an event in the twelfth month of one Japanese year often falls in the following year by the Western calendar — the Battle of Mikatagahara is the standard example, dated to both 1572 and 1573 depending on which calendar is used.
