# Historical dating (`historical_dating`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Approximate date of creation of a historical or museum object written as text, with a century, a part of a century, a decade or a range of them, such as 19th century, early 20th century or 1950s. Museum and archive catalogues use this free form when the exact date is not known, so it has no regular expression. This record covers the English notation; the Russian one is ru_historical_dating.
