I believe Slawomir is mistaken in thinking that on the introduction of the Gregorian calendar in 1582 Pope Gregory XIII removed 11 days from the calendar; it was in fact 10 days. By 1752, when Great Britain (and the American colonies) tranferred from the Julian to the Gregorian calendar the difference had drifted on a further day and eleven days were removed in those countries, hence the cry:"Give us back our eleven days".
Of course, some simple folk felt that eleven days of their lives had been stolen and there are always people ready for a good punch-up (Britain at that time was ruled by oligarchy tempered by riot) but the real trouble was that the next quarter day, the day the rent was due, was going to arrive eleven days early, a most unwelcome fact.
