Since 1971, the holiday has been fixed to the second Monday in October, coincidentally the same day as Thanksgiving in neighboring Canada (which was fixed to that date in 1959). It is generally observed today by banks, the bond market, the U.S. Postal Service and other federal agencies, most state government offices, and some school districts. Most businesses and some stock exchanges remain open, however some states and municipalities abstain from observing the holiday.[5]
That's right, the State of Hawaii does not observe this federal holiday
