Perhaps most intriguing about Half Day is its name, which provokes more interest and debate than any other place name in the northwest suburbs of Chicago.
Contrary to popular theory, the town of Half Day was not named because it was a half day’s journey from Chicago. The town’s true name was Halfda in honor of a friendly chief.
Chief Atakisic (Aphis), of the Potawatomie tribe, was a Native American leader of great standing in this area in the early 1800s. The friendly tribes of Potawatomie Indians were the first settlers to arrive in 1730 in what is now known as Lincolnshire.
