The Gregorian Calendar Adopted in England

In 1750 England and her empire, including the American colonies, still adhered to the old Julian calendar, which was now eleven days ahead of the Gregorian calendar, introduced in 1582 by Pope Gregory XIII and in use in most of Europe.

Attempts in the sixteenth and seventeenth centuries to adopt the new calendar had broken on the rock of the Church of England, which denounced it as popish. The prime mover in changing the situation was George Parker, second Earl of Macclesfield, a keen astronomer and a Fellow of the Royal Society. He was assisted in his calculations by his friend James Bradley, the astronomer royal, and he gained the influential support of Philip Dormer Stanhope, the sophisticated fourth Earl of Chesterfield (of letters to his son fame), who squared it with Henry Pelham’s initially reluctant government.
