This is a documentation subpage for Template:Ma. It contains usage information, categories, and other content that is not part of the original template page. |
Usage
Use the format {{Ma|Years_ago|Suffix|error=Error|round=Degree of accuracy}}
Years_ago can take a number (don't include commas, which are added automatically), or a period name (e.g. Cambrian), in which case it will return the date the period started.
Suffix is optional and defaults to "million years ago".
Error is an uncertainty and will be displayed as ± error. If a non-numeric value is entered, it will show the error associated with the period specified in Years_ago.
Degree of accuracy is the point at which to round the figure, as per the #expr: parserfunction. 0 will chop the figure at the decimal point; -1 will round it to the nearest 10; 1 will allow one decimal place.

Rationale
With geological time, it is often genuinely useful for the lay reader, with little grasp of how long ago 500 million years really is, to be able to quickly flick to a timescale. This template allows an easy way to implement such links.
