New Year’s Eve is not a federal holiday. December 31 does not appear on the list of legal public holidays in federal law, so federal offices stay open, mail is delivered, and government services run on a normal schedule. There is one exception worth knowing: when January 1 falls on a Saturday, the observed federal holiday shifts back to Friday, December 31, and federal workers get a paid day off that day.
When December 31 Becomes an Observed Holiday
Federal law handles weekend holidays with a shifting rule. When a federal holiday lands on a Saturday, the preceding Friday becomes the observed holiday for employees on a standard Monday-through-Friday schedule. When it lands on a Sunday, the following Monday is observed instead.1Office of the Law Revision Counsel. 5 USC 6103 – Holidays
So whenever January 1 falls on a Saturday, December 31 (a Friday) functions as the observed federal holiday for New Year’s Day. Federal offices close, employees get the day off, and government services shut down as they would on any other federal holiday. The next time this happens is December 31, 2027, when New Year’s Day 2028 falls on a Saturday. The Office of Personnel Management already lists that date on its 2028 federal holiday schedule.2U.S. Office of Personnel Management. Federal Holidays
For 2026, January 1 falls on a Thursday, so the shifting rule doesn’t apply. December 31, 2025 (a Wednesday) and December 31, 2026 (a Thursday) are both ordinary working days for the federal government.
What’s Open on New Year’s Eve
Because December 31 is a standard business day in most years, government operations continue without interruption.
Mail and Post Offices
USPS delivers mail on New Year’s Eve and keeps post offices open, though some branches may run reduced hours. Blue collection boxes follow their normal pickup schedules. The next day is different: on New Year’s Day, USPS closes all retail locations and suspends delivery.3USPS. USPS Holiday Service Schedule
Banks and the Federal Reserve
The Federal Reserve System remains open on December 31, so banks process transactions, wire transfers settle, and ACH payments go through normally. On January 1, the Fed closes and electronic fund transfers stop processing until the next business day.4Board of Governors of the Federal Reserve System. K.8 – Holidays Observed by the Federal Reserve System 2026-2030 If you’re making a time-sensitive payment or transfer, New Year’s Eve is your last window before the shutdown.
Federal Agencies and Courts
Agencies like the Social Security Administration and the IRS keep regular hours on December 31. Social Security offices close only on the 11 designated federal holidays, and New Year’s Eve isn’t one of them.5Social Security Administration. Holiday Closings of Social Security Offices Federal courts hold their normal schedules as well.
Financial Markets Split on December 31
Stock exchanges and bond markets handle New Year’s Eve differently, and the mismatch catches people off guard.
The New York Stock Exchange and Nasdaq both operate regular hours on New Year’s Eve 2026, open at 9:30 a.m. and closing at 4:00 p.m. Eastern. Neither exchange lists December 31, 2026, as a holiday or early-close day on its official calendar.6NYSE. Holidays and Trading Hours7Nasdaq. U.S. Stock Market Holiday Schedule That contrasts with Christmas Eve, when both exchanges close early.
The bond market is different. SIFMA, the trade association that sets the bond market’s holiday calendar, recommends an early close at 2:00 p.m. Eastern on December 31, 2026.8SIFMA.

When the President Closes Offices Anyway
Even in years when December 31 isn’t an observed holiday, the President can issue an executive order closing federal offices and excusing employees from work on specific days. In December 2025, an executive order closed all executive departments on December 24 and December 26, treating those days like holidays for pay and leave purposes under 5 U.S.C. § 6103(b).9The White House. Providing for the Closure of Executive Departments and Agencies of the Federal Government on December 24, 2025, and December 26, 2025
A president could do the same for December 31 in any given year. These orders are unpredictable and often come just days before the holiday, so federal employees can’t count on one. When it happens, though, the practical effect matches a regular federal holiday.
Year-End Deadlines That Still Hit at Midnight
Because December 31 is a working day, several money deadlines expire that night with no grace period.
Charitable contributions must be delivered by December 31 to count on the current-year tax return. For checks, the delivery date is the day you mail the check, not the day the charity deposits it. Credit card charges count in the year you make the charge, regardless of when you pay the bill.10Internal Revenue Service. Publication 526, Charitable Contributions
If you’re 73 or older with a traditional IRA or employer retirement plan, you must take your required minimum distribution by December 31 each year, or the IRS imposes an excise tax on the amount you should have withdrawn.11Internal Revenue Service. Publication 590-B, Distributions from Individual Retirement Arrangements Roth conversions and tax-loss sales work the same way: the transaction has to be completed within the calendar year, so the last open market day is your effective cutoff.
States and Private Employers Aren’t Bound by the Federal List
The federal holiday calendar doesn’t reach anyone outside the federal government. State and local governments set their own schedules, and some designate December 31 as a paid holiday for their public employees. Whether local offices are open on New Year’s Eve varies by jurisdiction, so check your state or county government’s website rather than assuming federal rules apply.
Private employers have even more room. No federal law requires a private company to give employees paid time off for any holiday, including New Year’s Eve or New Year’s Day. The Department of Labor is explicit: the Fair Labor Standards Act does not require payment for time not worked on holidays, and holiday pay or premium pay for working a holiday is a matter of agreement between employer and employee.12U.S. Department of Labor. Holiday Pay Half-days, early closures, and holiday pay on December 31 are voluntary benefits when offered, not legal requirements.
