Only 11 days were deleted at that time. Countries which adopted the Gregorian calendar later may have had to delete more (the difference is three days per 400 years). -- Jim Moseman @ CONCURRENT Computer Corporation, Tinton Falls, N.J. ...!vax135!petsd!jjm

Actually, most of Western Europe had already made the conversion centuries before Great Britain and its colonies did in 1752. The new calendar is named Gregorian, after Pope Gregory, who ordered the first change since the time of Julius Caesar (whence came "Julian"). Since the Pope was not much appreciated in Britain at the time, it took a while to convince the King and Parliament to adhere to the new standard. Bob Goudreau

First off it's 11 days not 12. The reason they had the "give us back our
11 days" riots, was that landlords were trying to charge a full months rent
instead of pro-rating it. It took an Act of Parliament to get the
landlords to only charge for 2/3 of a month.

I'm kinda amazed that all these questions about the date(1) command have come up! When I told someone else about all this going on here in net.bugs (!), they asked me, "Was this posted on April 1st?" Well, was that question about Sept. 1752 for real or an April Fool's joke? I hope you guys realise that the Unix manual pages *define* what features/abilities and sometimes defects each component (command, system call, subroutine, etc) has, along with other supplied documentation. I thought this was obvious, but then this is my job! I work in UTS Product Support and I fix bugs and decide what the product component *should* do, based on what the documentation says (and sometimes I even have to change the documentation!). In any case, I always make sure that the manual page is correct, clear, and true. Because I consider it the definition of the component. (the ultimate authority is the System V Interface Definition, of course). So, either we have seen a lot of cute jokes, or some people don't realise how helpful it might be to real the fruitful manual! -- Gordon A.
