President Ulysses S. Grant signed the law on June 28, 1870. In 1885, Christmas was formally declared a federal holiday. Usually, federal holidays are celebrated with a day free from work. This being said, if the Montgomery County school board chooses to "strip" religious holidays from "their" calendar, then they should also choose to have their schools open on Christmas Day! If you choose to "strip," then you must take your "stripping" to finality and continue the school's daily activities.
