A federal holiday means mail stops, banks close, and store hours vary widely. When the confetti settles and the ball has dropped, many Americans will wake up on New Year’s Day — Thursday, Jan. 1, 2026 — with errands to run, groceries to buy, or just the urge to grab coffee. But because New Year’s Day is a federal holiday, the holiday clock affects a wide range of services differently: some go dormant for the day, others hum along with normal or modified hours, and a few offer the convenience you might need as you kick off the new year.
