change from Julian calendar to the Gregorian calendar.

This Day in History:  September 2nd, 1752 “Great Britain moved from using the Julian calendar to the Gregorian calendar on Wednesday 2 September 1752. By this time, the two calendars were out by 11 days, so the following day was Thursday 14 September! This caused issues for objects like this one – a medal featuring a perpetual almanac. It was calculated using the Julian calendar and the dates therefore became obsolete.”

“There is a myth that people rioted asking for their eleven days back, which was stirred up by a satirical painting by William Hogarth, of which he also made an engraving, which you can see in the collection.”  This sometimes gets me confused when dealing with period documents around this time.
