The TMG v4.x Reference Manual states that the calendar makes no adjustments
for calendar changes within any individual country (p. 25). I assume this
follows TMG's philosophy of not making assumptions for the user. In
addition, deleting September 3-13, 1752 would make the calendar inaccurate
for some international users. On a related note, even in British America it
isn't safe to assume that all dates before September 2, 1752 are old style
(Julian calendar). While Parliament made the Gregorian calendar effective
in 1752 within Great Britain and its colonies, immigrants to America from
countries that had already adopted the Gregorian calendar sometimes used new
style dates before 1752. See Mark M. Smith, "Culture, Commerce, and
Calendar Reform in Colonial America," The William and Mary Quarterly, 3rd
ser., 55 (1998): 557-584.
