Arguably so, but I don't think there's anywhere in the POSIX localization data structures to store that information. There's a huge variety of adoption dates, from Oct 5/15, 1582 (Most Catholic countries of Western Europe) to March 10/23, 1924 (Greek civil usage). Plus, even within its limited US/historical UK application, the cal(1) program is still (admittedly so on its own man page) inaccurate for dates prior to 1751, because it uses January 1 as the first day of the year. While that was true in the original design of the calendar as instituted by Caesar in 45 BC, and has been true in England and her colonies since 1751, at some point way back when England had started counting the year change on March 25. That was a gradual change with no clear transition date, so matching historical practice exactly is pretty much impossible for a large chunk of Isle history.
