Template:Japanese year/doc

This template converts a year number in the Gregorian calendar into the corresponding era year in the Japanese calendar. It depends on the Nengo, Japanese era, and Japanese year number templates. If the era cannot be determined by the Nengo template, the output of this template will be blank. If the given year is a transitional year between eras, the new era's year will be given for the entire year, disregarding month and day of the actual transition date.

This template expects the Gregorian year to be passed either using the named  parameter or the first unnamed parameter.
