Takes a year from the name of the page and converts it into a range, by applying ((Year2range)) to ((Title year)). It does not pass through the ((Title year)) parameters but can take a parameter to specify the range, which is 1 year by default. So e.g. on Category:2024 in France:
((Title year2range))
→ 2024–25((Title year2range|1))
→ 2024–25((Title year2range|5))
→ 2024–29((Title year2range|-5))
→ 2024–19To go the other way, to generate a year from a range in the page name, you just use ((Title year)) (or ((Title year+1)) or ((Title year-1)) as appropriate)
