Counting down to 12 July 2027
Why 12 July 2027?
In the summer of 927, Æthelstan captured York — the last Viking kingdom in England — and the other rulers of Britain submitted to him at Eamont, near Penrith, on 12 July 927. That is the day England first existed as a single kingdom, and the reason the campaign treats it as the nation’s birthday. The full story is told in the birth of England, 927.
How old will England be?
1,100 years old. Founded in 927, England has been a single, unified country for eleven centuries — a claim only a handful of nations can make, and the reason England is so often counted among the oldest countries in Europe.
Will there be a bank holiday?
