Please be very careful touching any political phrasing around
time. Timezones are political entities.

OpenBSD's phrasing:

     The Gregorian Reformation is assumed to have occurred in 1752 after the
     2nd of September.  By this time, most countries had recognized the
     Reformation (although a few did not recognize it until the early 1900s).
     Eleven days following that date were eliminated by the Reformation, so
     the calendar for that month is a bit unusual.

Ubuntu and FreeBSD's phrasing (and a new flag):

     -s country_code
             Assume the switch from Julian to Gregorian Calendar at the date
             associated with the country_code.  If not specified, ncal tries
             to guess the switch date from the local environment or falls back
             to September 2, 1752.  This was when Great Britain and her
             colonies switched to the Gregorian Calendar.
