Template:Make YYYY–YY
This template creates a year YYYY–YY range (e.g. 1934–35 or 1984–1989), based on parameters which supply a base year, an optional offset, and an optional span.
Purpose
This is intended as a helper template for use in constructing other templates. In situations where there is a need to generate a date range with a two-digit ending year, the markup is complicated by the fact that if the ending year ends in 00 (e.g. 1300, 1900, or 2000), then it needs to be written a 4-digits.
For example, a range of one-year span starting in 1999 is written as 1999–2000, because 1999–00 would be ambiguous.
This template allows year ranges to be generated without a clump of impenetrable code.
Policy
Per the Wikipedia Manual of Style (MoS) at MOS:DATERANGE, two-digit ending years are generally deprecated, but are permitted in some limited circumstances. Please check the MoS before using ranges with two-digit ending years.
Usage
{{Make YYYY–YY|base year|offset|span}}
All parameters are optional
Parameters
All parameters are unnamed
- The base year is the year from which the start year is calculated. If it is omitted, the current year is used.
- The offset is a number which is added to the base year, to calculate the start year. This useful when the start year is a parameter supplied to the calling template.
- The span is the length of the range; e.g.
2004–05has a span of 1, while2004–09has a span of 5. The default is 1,

Sample use case
The by-year sub-categories of Category:Australian soccer by year are each parented in two year-range categories.
For example:
- Category:1995 in Australian soccer is a sub-category of Category:1994–95 in OFC football and Category:1995–96 in OFC football
- Category:1999 in Australian soccer is a sub-category of Category:1998–99 in OFC football and Category:1999–2000 in OFC football
The cathead template {{YYYY in Australian soccer category header}} would need some ugly markup to generate those category names, but with this template, the code is simple:
[[Category:{{Make YYYY–YY|{{Title year}}|-1}} in OFC football|Australia]]
[[Category:{{Make YYYY–YY|{{Title year}}}} in OFC football|Australia]]
