Template:Year in country category/doc

Purpose
This template is intended to be used on year in country categories (for example, Category:2008 in Canada or Category:1538 in England). It creates a "timeline" style table of links to categories for adjacent years before or after it in the same decade (see example below).

Parameters
The first three parameters indicate the country and its continent(s).
 * The first parameter is the country name as indicated in the category name (but without prefixes which are unwanted for sorting, these should be added to the 4th parameter).
 * The second parameter is the continent where the country is located.
 * The third parameter is optional: if a country is located in two continents (mainly for countries in Europe and Asia, like Russia or Turkey), then a second continent can be included here. The order of the two continents is not important. This third parameter can also be used with member states of the United Kingdom (use "United Kingdom"), the former Soviet Union ("Soviet Union"), or former Yugoslavia ("Yugoslavia").
 * The 4th parameter is used for sorting of countries which start with "The" (or other prefixes like "the Socialist Republic of "): this can be left empty for most countries.

Optional parameters
This is used for countries such as Yugoslavia and the Soviet Union, which existed only within one century.
 * yes — instead of categorising the page in "Category:Years of the nth century in CountryName", use "Category:Years in CountryName".
 * Note: As an alternative mechanism with the same result, if the page "Category:Years of the nth century in CountryName" is redirected to "Category:Years in CountryName", this template will resolve the redirect and use the latter instead (e.g. Category:Years in Czechoslovakia).


 * new name — use new name for parent categories where appropriate
 * new name start year — changeover year for new name

Simple example
In most cases, only two parameters will be needed: the country and the continent.

When placed on the page Category:1867 in Japan: ""
 * displays the following:

Example using all unnamed parameters
When placed on the page Category:1954 in the Socialist Republic of Macedonia: ""
 * displays the following:

Example using newname parameters
When placed on the page Category:1771 in Thailand: generates the following parent categories:
 * Category:1770s in Thailand – because the decade ends before the start date 1782
 * Category:Years of the 18th century in Siam – because the century ends after 1782
