instant gratification: Columbus Day clarified in Wikipedia

Columbus Day - Wikipedia, the free encyclopedia: Who's open, who's closed, who's more laid back than usual today, and are those truants, the assured future for the welfare system, standing on the corner?

"Since 1971, the holiday has been commemorated in the U.S. on the second
Monday in October, the same day as Thanksgiving in neighboring Canada. It is
generally observed today by banks, the bond market, the U.S. Postal Service and
other federal agencies, most state government offices, and many school
districts; however, most businesses and stock exchanges remain open."
