Blue law

The phrase "Blue law" refers to a type of law, typically originating from religious beliefs, that restricts or prohibits certain activities or transactions on Sundays or other specific days of the week. These laws often target activities that are deemed secular or non-religious in nature, such as the sale of alcohol, gambling, dancing, or even certain types of business transactions. Blue laws are intended to promote religious observance, encourage rest or leisure, and preserve a sense of community values. However, they have faced criticism for infringing on individual freedoms and interfering with business operations. The term "blue law" is believed to have originated from the use of blue paper to print such laws in colonial America.
