Template:Copr countdown/doc

Documentation
copr countdown is used to calculate the time until the end of a given year. It's useful for expressing the current copyright status of a work whose copyright is about to expire within the next few years.

It takes one or two arguments:
 * First argument: Year at whose end the event occurs
 * (optional): message to display on expiry; otherwise, "public domain" is used

For events that have not yet occurred, the time is expressed as a number of years (rounded up) or a number of days (rounded up).

Limitation: This template does not automatically update for legislative extensions of the copyright term, such as those in the European Union and in the United States. Country-specific templates that transclude copr countdown, which add a constant to a given year of publication or death of the author, are recommended if this template will be used often.
