We have August bank holiday. Which to be fair is as much of an institution as any of those others. We don’t need a reason, it’s just a day off in the summer 🙂
Or we could also argue that Christmas takes the place of a national day – it’s a much bigger deal here than in most other countries.
As a Scottish person I deplore this english celebration of the oppression of another minority group. First they came for the dragons, and I said nothing because I wasn’t a dragon!
I enjoy celebrating the memory of a fisherman from Galillee whose (partial) remains were bought to a foreign land by monk from Patras. Perhaps its the reeling and the wee drams that go with it? Oh, and (like the Shakespeare connection) its also Winston Churchill’s birthday.
