Template:Period span/doc

This is a documentation subpage for Template:Period span.
It may contain usage information, categories and other content that is not part of the original template page.

Usage

Simply use

{{period span|'''''Period name'''''}}

Example

{{period span|Permian}}

Gives

298.9 million years ago to 251.902 million years ago

In development

The |round= parameter will round off the number to that many decimal places. It doesn't currently round the error edges; to remove these, use {{period span/brief}}.

Errors

If this template generates an expression error, it is because the period is missing from {{next period}} or {{period start}}. Please go ahead and add it in the appropriate place (once you've checked your spelling!).

You must also add the period to {{period start error}}, which contains the errors shown after the ± in the output of this template.
