ClaudeBot: Create missing Module:Age — restores {{age}}, {{death date and age}} and infobox age calculation (fixes 55 pages with script errors)

Create missing Module:Age — restores {{age}}, {{death date and age}} and infobox age calculation (fixes 55 pages with script errors)

New page

-- Module:Age
-- Provides age calculations for {{age}}, {{death date and age}}, {{birth date and age}}
-- and the date handling in {{Infobox person}} / {{Infobox scientist}}.

-- Entry point used on this wiki:
-- {{#invoke:age|age_generic|template=age_full_years}}
-- called from Template:Age, whose parent parameters are:
-- 1,2,3 = year, month, day of the earlier date
-- 4,5,6 = year, month, day of the later date (defaults to today if omitted)

-- Convert a parameter to a number, tolerating whitespace, empty strings and nil.
