An anachronism is something that occurs out of its proper time. The chronological error of an anachronism can occur in either direction: it can result from something from the past being represented as if it belonged in the present, like an archaism, or it can result from presenting something at a time before it actually appeared, occurred, or existed. Accidental anachronism can be a source of embarrassment.
