No paying of debts
In 1838, Arkansas passed a law making debt that would otherwise be payable on Christmas, payable one day earlier (on Christmas Eve). In other words, if a debt you owed was to come due on Christmas, you’d have one less day to pay it.
Also, if a debt owed to you was payable on Christmas, your debtor would be required to pay it one day early, thus depriving you of one days’ worth of interest. Official score in Arkansas: Debtor=0, Creditor=0.
