This module is used to calculate dates in theJapanese calendar. It defines an "era"class which is designed to be called from other Lua modules, and it also contains several functions to export Japanese calendar data directly to Wikipedia pages through #invoke.
{{#invoke:Japanese calendar|function_name|year=year|era=article name or kanji|previous=yes|next=yes}}The function name specifies how the data should be outputted. Theyear andera parameters determine what era and year the module outputs. Thenext andprevious parameters tell the module to return data for the next or previous era, rather than the one specified. If a combination of parameters is invalid the module will usually output nothing. However, if both thenext andprevious parameters are specified it will output an error.
Theyear parameter is the year in theGregorian calendar. Theera parameter can either be the article name for that era, or the era's name inkanji. (Transcribed English era names can usually be used, but will not work if they are ambiguous.) Eitheryear orera must be specified. If both are specified, the module defaults to usingera to get the era data. This enables output of the last year of the previous era (for example, Shōwa 64 is the same year as Heisei 1).
| Code | Output |
|---|---|
{{#invoke:Japanese calendar|link|year=1950}} | Shōwa |
{{#invoke:Japanese calendar|link|era=Shōwa period}} | Shōwa |
{{#invoke:Japanese calendar|link|era=昭和}} | Shōwa |
{{#invoke:Japanese calendar|link|era=Shōwa}} | |
{{#invoke:Japanese calendar|link_year|year=1989}} | Heisei 1 |
{{#invoke:Japanese calendar|link_year|year=1989|era=Shōwa period}} | Shōwa 64 |
{{#invoke:Japanese calendar|link_year|year=1990}} | Heisei 2 |
{{#invoke:Japanese calendar|link_year|year=1990|era=Shōwa period}} |
| Code | Description | Example |
|---|---|---|
baseyear | The first year of the specified era. | {{#invoke:Japanese calendar|baseyear|era=Heisei}} → 1989 |
endyear | The last year of the specified era. | {{#invoke:Japanese calendar|endyear|era=Shōwa period}} → 1989 |
year | The year for the specified era, without the era name. Defaults to the newer era, if more than one is applicable. | {{#invoke:Japanese calendar|year|year=1989}} → 1 |
kanjiyear | The same asyear, but inkanji. The first year of an era is changed to the kanji 元, and the others are changed tofull-width numbers. | {{#invoke:Japanese calendar|kanjiyear|year=1989}} → 元 |
article | The Wikipedia article for the era, unlinked. | {{#invoke:Japanese calendar|article|year=1950}} → Shōwa (1926–1989) |
label | The name of the era. Same asarticle forundisambiguated titles. | {{#invoke:Japanese calendar|label|year=1950}} → Shōwa |
link | A link to the Wikipedia article of the specified era. | {{#invoke:Japanese calendar|link|year=1950}} →Shōwa |
kanji | The kanji for the specified era. | {{#invoke:Japanese calendar|kanji|year=1950}} → 昭和 |
label_year | label followed byyear | {{#invoke:Japanese calendar|label_year|year=1989}} → Heisei 1 |
link_year | link followed byyear | {{#invoke:Japanese calendar|link_year|year=1989}} →Heisei 1 |
label_kanjiyear | label followed bykanjiyear | {{#invoke:Japanese calendar|label_kanjiyear|year=1989}} → Heisei 元 |
link_kanjiyear | link followed bykanjiyear | {{#invoke:Japanese calendar|link_kanjiyear|year=1989}} →Heisei 元 |
If thenext parameter is specified, the module outputs the data for the subsequent era; if theprevious parameter is specified it outputs the data for the previous one. If theold parameter is specified, the module outputs the data for the "old" era. This is the same as the current era unless the year is set to the first year of the specified era. If this is the case, thenold outputs the data for the previous era. However, if the module could not find a valid previous era then the data for the current era is returned.
| Code | Output |

First of all, the era class must be loaded, like this:
local era = require( 'Module:Japanese calendar' ).eraOnce the class is loaded, you can make a new era object usingera:new():
local myEra = era:new{ year =year, era =article name or kanji }Eitheryear orera must be specified. It is also possible to use anindex field, corresponding to the index ofModule:Japanese calendar/data, but this is for internal use only and will change as new eras are added.
Era objects have a number of properties. Their values might benil if the module did not have enough information to process them, or the values could befalse if they correspond to an invalid era. You can specify properties with the dot syntax:
local article = myEra.articleThe properties are as follows:
gregorianYear: the year in theGregorian calendar. Same as the input year.startYear: the first year of the specified era.endYear: the last year of the specified era.eraYear: the year of the specified era, without the era name.eraYearKanji: a string representing the era year inkanji. The first year of an era is changed to the kanji 元, and the others are changed tofull-width numbers. Note: even though the output may often look like a number, it will always be a string value.article: the Wikipedia article for the era, unlinked.label: the name of the era. Same asarticle unless the article title isdisambiguated.kanji: the name of the era in kanji.Era objects have three methods. Methods can be specified with the colon syntax:
local nextEra = myEra:getNextEra()The methods are as follows:
era:getNextEra() - gets the era object for the next era. Returnsnil if it doesn't exist.era:getPreviousEra() - gets the era object for the previous era. Returnsnil if it doesn't exist.era:getOldEra() - gets the era object for the "old" era. This is the same as the current era object unless eraYear equals 1. If eraYear equals 1 then this returns the era object for the previous era. If the module could not find a valid previous era object then the current era object is returned.-- This module stores the data for [[Module:Japanese calendar]]. The formatting is as follows:---- {-- article = "Shōwa (1926–1989)", -- The Wikipedia article about the era.-- startYear = 1926, -- The year that the era started.-- endYear = 1989, -- The year that the era ended.-- kanji = "昭和", -- The kanji for the era.-- label = "Shōwa" -- The romaji for the era, if the article name is disambiguated.-- },---- The "label" field may be absent some or most of the time, and the "article" and "kanji" values-- may be set to "" (the blank string) if it is a period between era names.-- See [[Japanese era name]] for more details on era names and how they correspond to-- Gregorian calendar years.eras={{article="Reiwa",startYear=2019,kanji="令和",},{article="Heisei",startYear=1989,endyear=2019,kanji="平成",},{article="Shōwa
