-Defines which date information used to construct the \bibfield{extradate} field. With the default setting for \cmd{DeclareExtradateContext}, this field (see \secref{aut:bbx:fld:lab}) is printed to disambiguate works by the same \bibfield{labelname} (usually the author) or \bibfield{labeltitle} (usually the main title) which occur in the same date scope. By default, the date scope is the year and so two works by the same author/title within the same year will have different \bibfield{extradate} values which are used to disambiguate the works in the bibliography in the usual manner seen in many authoryear type styles. The \prm{specification} is one or more \cmd{scope} specifications which can contain one or more \cmd{field} specifications. Within a \cmd{scope}, the existence of each \cmd{field} will be checked and if found, the first \cmd{field} is used and the rest are ignored. This allows a fallback in case certain fields are not available in all entries. All \cmd{scope}s are used to track information and \cmd{scope}s should be specified in decreasing order of generality (e.g. year then month then day etc) The default definition is:
