A Guide to Federal Holidays in Business Day Counts

What to take away

The costly one: a settlement built on the wrong bank calendar

A treasury analyst schedules an ACH settlement ten business days out and marks Columbus Day as a bank closure. The date comes back a day early. The payment lands late, the counterparty applies a fee, and the team spends a week explaining it.

The cause is one list used for two jobs. The eleven federal holidays are set by statute at 5 U.S.C. 6103, and Executive Order 11582 sets how agencies observe them. OPM publishes the federal holiday list for agencies and their deadlines. The Federal Reserve publishes its own holiday schedule for banking business days, and it drops Columbus Day and Veterans Day. That is a two-day gap.

Prevention is a diff, not a rule of thumb. Pull both schedules, line them up, and mark the days where they disagree.

Here is the full statutory list, all eleven: New Year's Day, Martin Luther King Jr. Day, Washington's Birthday, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving Day, and Christmas Day.

Federal Reserve Banks close on nine of them. Martin Luther King Jr. Day, Washington's Birthday, Memorial Day, Labor Day and Thanksgiving Day always land on a weekday, so they never move. Columbus Day and Veterans Day are the two the Federal Reserve works through.

The remaining holidays carry fixed dates and can land on a weekend. Executive Order 11582 governs the shift: a holiday falling on Saturday is observed the Friday before, and a holiday falling on Sunday is observed the Monday after. The business-day count follows the observed date, not the printed one, so a shift is only correct when the printed date really falls on a weekend.

Private employers are bound by neither list; the payer's bank and the contract decide. Country calendars covers how national lists differ elsewhere, while this page stays on the US source.

The ones that look fine at first

Treating Juneteenth as optional is the first. It became a federal holiday in 2021, and some payroll calendars still carry the older list. Situation: a cutoff lands on June 19. Consequence: deposits post against an unfunded account. Prevention: confirm whether the originating bank closes before setting the cutoff.

Reusing last year's calendar is the second. Fixed-date holidays land on a different weekday each year. Situation: a team copies the prior sheet because the holiday names match. Consequence: every observed shift is wrong. Prevention: rebuild from verified dates and sources each January.

Reading legal holiday as federal holiday is the third. For court deadlines the two are close, but the court's own rule controls. Federal Rule of Civil Procedure 6(a) defines a legal holiday and covers how a period continues past a weekend or legal holiday, rolling the due date to the next business day.

The ones that only show up later

Some errors sit in the ledger for months before anything lands on them. A holiday table keyed once into a spreadsheet keeps returning a plausible number. February is fine. April is fine. The drift first appears in an October reconciliation, when a June settlement date fails to match the bank statement.

A wrong holiday row is invisible until a deadline falls on it, and then it is the only thing anyone discusses.

Mortgage work has a delayed failure of its own. The Closing Disclosure waiting period runs on a definition of business day that counts Saturdays along with certain legal holidays. A team that drops Saturday shortens the window on paper only. The closing still waits, and the rate lock keeps ticking.

Example: a five-day count that slipped by one

Start on Wednesday, July 1, 2026, and add five business days. Independence Day falls on Saturday, July 4, so the observed closure is Friday, July 3.

A calendar that marks only July 4 gives July 2, 3, 6, 7, 8 and returns July 8. A calendar built from the Federal Reserve schedule closes July 3 and returns July 9. One row, one day of drift, and a wire that arrives on the wrong side of a cutoff.

The same arithmetic drives any add-business-days count used for payroll or retail scheduling.

What they have in common

Each failure comes from the same habit. The calendar was built once, from one source, and never checked against the source that governs the transaction. Agency work follows OPM. Bank settlement follows the Federal Reserve. Court filings follow the court's rule.

The fix is small and dull. Date-stamp the holiday table. Name the source behind each row. Add one check that fails when the year rolls over. Where a count touches money or a filing, the calendar should be re-derived, not remembered. A formula that pins any year's workday total applies the same discipline to whole years.

IRS Publication 509 prints the federal tax calendar and defines legal holidays for due dates.
