About
{{Category series navigation}} is intended to be a minimal-input, near-universal template for automatically navigating most numerically adjacent categories.
| Type | Example category | BC(E)? | Example output |
|---|---|---|---|
| Season | 2001–02 FA Cup | No | |
| TV season | Futurama season 1 episodes | – | |
| Office term (regular) | MEPs 2004–2009 | No | |
| Office term (irregular) | Wales AMs 2003–2007 | No | |
| Numerical range | Taxonbars with 30–34 taxon IDs | – | |
| Decade | 1990s in Scotland | BC | |
| Year | 1999 in Scotland | BC(E) | |
| Year (auto-condensed) | Candidates in the 2000 US presidential election | – | |
Year (|skip-gaps=yes) |
Amusement parks opened in 1877 | – | |
| Ordinal (temporal) | 2nd-century rabbis | BC(E) | |
| Ordinal (numeric) | 9th Lok Sabha | – | |
| Ordinal (word) | First Dynasty of Egypt | – | |
| Roman numeral | Deputies of Legislature X of the Kingdom of Italy | – | |
| Mixed decade | 1760s in the Province of Quebec (1763–1791) | – | |
| Mixed year | 1778 establishments in the Province of Quebec (1763–1791) | – | |
Searching behavior
Most multi-year seasons/office terms/numerical ranges are acceptable, as long as the season duration/term length/range size is <= 10, and the gap between seasons is <= 6. For series exceeding either of these criteria, see/use {{Irregular category series navigation}}.
The length of each season is automatically determined from the originating category name, up to and including 10 years. MOS:DATERANGE compliance is preferred, but some deviation is allowed and tracked for regular series with seasons > 1 year long. {{Category redirect}}s are followed, and tracked for either MOS contravention (to be corrected) or for navigational aid (no error). The gap size between successive seasons is also automatically determined, up to and including 6 years, and defaults to 0 (e.g. 1995–96 → 1996–97).
Automatically condensed years are supported for presidential categories only (but can be easily expanded as needed), for gaps up to and including 5 years, and defaults to 1. To skip gaps of up to 50 years in any year categories, use |skip-gaps=yes.
Limitations
Numerical limitations and AD/BC/E
- Season/office term categories do not work for any years BC, which will be hidden, because no working examples were found.
- Decade categories recognize BC, but not BCE, because no working examples were found.
- Ordinal & numeral words do not work above the ninety-ninth & ninety-nine, because no working examples were found.
Condensation
- Automatically condensed Olympics display is not supported due to peculiarities; use {{Winter Olympics by year category navigation}}, etc., instead.
- Automatically condensed years are supported for US presidential categories only, due to their consistency; use
|skip-gaps=yesas desired on other year categories. |skip-gaps=yescurrently only works when starting on a year category, and is not intended to find all hyphenated ranges, which allows it to span much larger gaps.
Work-arounds
- Base-name changes: create at least 2 logically numbered {{R from category navigation}} (1 backward & 1 forward), to join both related series.
- Unaccounted-for name+number conventions: where a fixed number is part of the prefix or suffix text, e.g. Chapter 11 bankruptcies, a non-breaking space may force the template to work. See this fix, where {{title year}} skipped over 11 as part of a word rather than a discrete number. (This case has been accounted for and is no longer required in this example.)
- General: for large, permanent gaps† between successive categories, use {{Preceding category}}, {{Category pair}}, {{Succeeding category}}, as needed, in addition to {{Category series navigation}} on both sides, or in the middle, of the gap. Even if {{Category series navigation}} is isolated, it has the benefit of confirming the absence of nearby categories to the reader or maintainer.
†Permanent gaps, where there is a confirmed permanent absence of data, and not just a temporary, yet to be filled, gap on Wikipedia. |skip-gaps=: create {{R from category navigation}} from an appropriate year to the hyphenated category that was not found.

Usage
- Typical usage
{{Category series navigation}}
- Specify a minimum and/or maximum year to display
{{Category series navigation|min=-100}}{{Category series navigation|min=100 BC}}{{Category series navigation|min=1753|max=1810}}{{Category series navigation|max=2030}}
- To skip gaps in year categories
{{Category series navigation|skip-gaps=yes}}

{{Category series navigation|follow-redirects=no}}
- Exceptional cases
{{Category series navigation|cat=2010s albums}}— to behave as if placed on|cat=; consider using {{Category pair}} instead of|cat=
Testing & debugging
To test the output of the template on a particular category name, use the |testcase= parameter, and |testcasegap= if necessary:
{{Category series navigation|testcase=1770s in the Province of Quebec (1763–1791)|min=1760}}→
{{Category series navigation|testcase=1770s in the Province of Quebec (1763–1791)|max=1790s}}→
To see all links produced and/or tested, and what effect each has on their display, use |list-all-links=yes:
{{Category series navigation|testcase=Nations at the 2013 World Athletics Championships|min=2008|skip-gaps=yes|list-all-links=yes}}→
- Category:Nations at the 2006 World Athletics Championships (2006) ()
