Copyright Duration Calculator

Estimate the copyright duration and expiration year for a creative work based on jurisdiction, work type, and publication details.

Jurisdiction

United States European Union / UK International (Berne Convention Default)

Type of Work

Individual Author Joint Authors Anonymous / Pseudonymous Work for Hire / Corporate Authorship

Year of Publication (or Creation if Unpublished)

Year of Author's Death (leave blank if still living)

Year of Last Surviving Author's Death (leave blank if still living)

Was copyright renewed (for US works published 1923–1963)?

Yes, copyright was renewed No, copyright was NOT renewed (now public domain) Not applicable
