How can I set the urlseen label of biblatex?

Question

I'd like to set the default visited on <date> to accessed on <date> (as per my teacher's specifications). I believe I need to change the urlseen label to accomplish this.

Is changing the urlseen label the way to go, and if so, how can I do this?

Answer 1

I found out that you can change the localization keys as described in Guidelines for customizing biblatex styles:

\DefineBibliographyStrings{english}{%
  urlseen = {accessed on},
}

See also the biblatex documentation under 4.9.2.15 Labels.
