A number of years ago, my sister and I were talking with a friend from England. In the course of the conversation, my sister asked our friend if the English celebrate a national day of Thanksgiving, as we do in the US every fall.
Perfectly deadpan, he replied, "Yes, we do, on July 4th."
To my fellow US citizens, happy Independence Day tomorrow. And to all our other friends, I hope you have a great day, however you choose to spend it.
