Overview#
Birthdate is a JSON Web Token Claims and a string representing the End-User's birthday, represented as an ISO 8601-2004 YYYY-MM-DD format.The year MAY be 0000, indicating that it is omitted.
To represent only the year, YYYY format is allowed.
Birthdate was added by the OpenID Connect Core 1.0 Standard
Note that depending on the underlying platform's date related function, providing just year can result in varying month and day, so the implementers need to take this factor into account to correctly process the dates.
