Costco will be open be from 10 a.m to 8:30 p.m. on Monday. Like most other stores, including competitors, like BJ’s, and fast-food chains, like Chick-fil-A, Costco typically remains open on Columbus Day, despite it being a federal holiday.

Most banks will be closed on Monday, known as Columbus Day or Indigenous Peoples' Day, but the stock market will be open as will most retail stores and restaurants. Oct. 14 is one of 11 federal holidays that the Federal Reserve observes during the year.

A number of states will recognize Monday as Indigenous Peoples' Day, however that won't be the case in Illinois, in Chicago or on a federal level.
