Template:Year2range
This template takes a year in the form of a positive number of up to 4 digits and converts it to a range, thus :
{{Year2range|2024}}→ 2024–25{{Year2range|{{CURRENTYEAR}}}}→ 2024–25{{Year2range| {{#expr:2024+1}} }}→ 2025–26{{Year2range| {{#expr:2024-8}} }}→ 2016–17{{Year2range|1999}}→ 1999–2000{{Year2range|1899}}→ 1899–1900{{Year2range|999}}→ 999–1000{{Year2range|32}}→ 32–33{{Year2range|3}}→ 3–4{{Year2range|}}→{{Year2range|12345}}→ Error!!

A second parameter can be used to specify the size of the range, with a default of 1 year if omitted :
