%JL%This Basic program can produce in Pipedream a calendar for the years 1 to 
%JR%2099.  Note that the calendars for the years 1582 to 1752 are only 
reliable for those countries which in 1752 were English-speaking.

%JL%1752 was the year when Britain and her dependancies, including America, 
%JR%changed from the Julian to the Gregorian calendar.  Other European 
%JL%countries, but not all, had changed between 1582 and 1700.  (Greece did 
not change until 1923!)

%JR%If you must see the calendar for 1752 then get the calendar for 1772 
%JL%which is the same as 1752 for the year up to Sept.2nd.  The calendar for 
%JR%1775 is the same as 1752 for Sept.14 to the end of the year.  The 3rd to 
%JL%the 13th of September for the year 1752 were `lost'.  There were riots in 
%JR%England because people believed their lives had been shortened by 11 days

%JR%The error between the calendar and the astronomical year arose because 
%JL%all centennial years up to 1752 were leap years, instead of, as now, only 
%JR%those centennial years where the first two figures are exactly divisible 
by four.  

%JR%Yes! you have worked out that the error was 13 days so why were only 11 
%JR%`lost'?  When the change, of ten days, was made in most of the rest of 
%JR%Europe near the end of the sixteenth century the same discrepancy 
%JR%occurred.  In fact, the change was based not on the incorrect number of 
%JR%leap-year days since Year 1 but in order to make March 21st coincide with 
the astronomical observation of the Spring equinox - so there!
%C%(Reference - Whittaker's Almanac - The Christian Calendar).

%JL%The veracity of the calendars before 1752 have been checked by reference 
%JR%to historical evidence where the days of the week for certain dates are 
%JL%reliable, e.g. the date of Columbus' sailing, the execution of Anne 
Boleyn and the battle of Crecy.      


%JL%You can, of course, get a printout of the calendar - it's in Pipedream.
