Why these close and others do not
Three separate rules decide what shuts on any given American holiday, and they do not always agree. The federal list in 5 U.S.C. § 6103 governs federal offices, federal courts and the U.S. Postal Service, and the Federal Reserve follows the same calendar — which is why banks close on federal holidays and stay open on state-only ones. State holiday statutes are separate: each state legislature sets its own list for state employees, courts, DMV offices and usually public schools, so a day can be a paid holiday in Texas and an ordinary Tuesday in Ohio. Private employers answer to niether, no federal law requires any private business to close or to pay a premium for holiday work, so retailers, restaurants and offices set their own policies, and most stay open with reduced hours on all but a handful of days.
Casimir Pulaski Day is a state holiday, so only the second rule applies: offices close in the states that observe it, while federal offices, post offices and banks stay open. The stock market keeps its own calendar again: the New York Stock Exchange and Nasdaq close for nine of the eleven federal holidays plus Good Friday, but trade normally on Columbus Day and Veterans Day, when the bond market closes and the equity market does not.
Hours vary by location and year. Check with the branch or office before you go. For dates through 2027 and the history, see the main Casimir Pulaski Day page.
