A template to assist making manually-configured category navigation for cases with very irregular seasons, which the regular {{Category series navigation}} cannot handle.
Background
{{Category series navigation}} is a very powerful tool. Without any parameters, it creates category navigation for sets of chronology categories of many types: years, decades, centuries, ordinals, and seasons (i.e. sets of categories where each category spans a range of years). However, technical limitations mean that it cannot handle seasons with irregular length and irregular inter-season gaps larger than 6 years.
This template eases the pain of manually creating category navigation for these irregular seasons, such as the subcats of Category:Legislators by term, where some parliaments have variable-length terms and large gaps.
Usage
{{irregular category series navigation|prefix|suffix|season1|season2|season3|...}}
Explanation
A season category will usually take the form "prefix year-range suffix". There is rarely both a prefix and suffix: most categories have one or the other.
- Example of prefix
- Category:Members of the Scottish Parliament 1999–2003 ... prefix =
Members of the Scottish Parliament
- Example of suffix
- Category:2000–2001 in Icelandic basketball ... suffix =
in Icelandic basketball
Example
For the subcats of Category:Members of the Hellenic Parliament by term:
{{irregular category series navigation|Greek MPs||1933–1935|1935–1936|1936|1946–1950|1950–1951}}
Note that since there is no suffix, the second parameter is left blank.
