This is needed because the articles on years take three different formats ("YYY" indicates a number, e.g. "6", "29", "754", "938")

• All BC years: YYY BC
• AD years 1 to 10: AD YYY
• AD years after 10: YYY

This template allows accurate links to be generated.

{{Year category name|YYYY}}

The parameter may be:

• A bare number for AD years, e.g. 123 or 1937
• A negative number for BC years, e.g. -45 or -1307
• A number preceded or followed by "AD", with or without a space, e.g. AD 17 or 1066AD
• A number preceded or followed by "BC", with or without a space, e.g. BC5 or 783 BC

Any other input will be ignored. There are no error messages.
