This year we’re in Scotland on August 28, so we are affected by the August Bank Holiday.
The August Bank Holiday was instituted by the Bank Holidays Act of 1871 to give bankers a day off so they could participate in cricket matches.
Since then, however, its significance has greatly expanded beyond those narrow limits. Now, it is a day intended to give workers of all stripes a three-day weekend before the summer holidays end and employees must return to the workplace and students to their schools.
(The video below says that they celebrate the August Bank Holiday on a different day in Scotland [August 7, 2017]. Where we were, they also celebrated August 28!).
