DUAL DATES PRIOR TO 1752
In 1752 England and Wales adopted the Gregorian Calendar, which had long been in use on the Continent. Because of this, it was necessary to remove eleven days from the month of September for that year to bring us into line with the rest of Europe. Also in 1752 the start of the year was moved from Lady Day, 25 March, to 1 January. Because of this it is customary to show events falling in the period 1 January to 24 March in the years prior to 1752 with two years e.g. 1745/46. Thus 1745 would be the year using the old calendar and 1746 would be the year according to the modern calendar.
