Okay kiddo, so back in 1871, there was a law that was made called the Bank Holidays Act. This law was important because it decided which days banks in England, Wales, and Northern Ireland would be closed.
In simple terms, a bank is a place where people go to put their money or take out loans. But just like any other job, the people who work at the bank need to take a break sometimes.
So, this law said that on certain days, like Christmas or New Year's Day, banks would be closed so the workers could spend time with their families and friends.
And why was it called the Bank Holidays Act? Well, because these days were like little holidays for the banks!
Overall, the Bank Holidays Act was an important law that made sure the people who worked at banks got time off to rest and have fun with their loved ones on special days.
