One business day is one weekday — Monday through Friday — on which banks and federal government offices are open for normal operations. Weekends (Saturday and Sunday) and federal bank holidays do not count as business days. Understanding what counts as a business day matters for bank transfers, direct deposit timing, check holds, credit card payments, and loan processing.

The Definition of a Business Day in Banking
For federal banking purposes, a business day is defined as any day the Federal Reserve Banks are open for business — which is Monday through Friday, excluding federal holidays. One business day is not 24 hours of continuous processing. It is a single calendar day on which banks operate, subject to daily processing cutoff times that vary by institution.
Most banks establish a daily cutoff time between 2:00 PM and 6:00 PM local time. Transactions received before the cutoff are processed on that business day. Transactions received after the cutoff — or on a weekend or holiday — are processed on the next business day. If you're wondering how long a business day is in hours, the answer depends on each bank's cutoff policy.
Federal Bank Holidays: Days That Are Not Business Days
The Federal Reserve observes 11 federal holidays each year. On these days, most banks do not process transactions, ACH transfers, or wire transfers:
- New Year's Day (January 1)
- Martin Luther King Jr. Day (third Monday in January)
- Presidents' Day / Washington's Birthday (third Monday in February)
- Memorial Day (last Monday in May)
- Juneteenth National Independence Day (June 19)
- Independence Day (July 4)
- Labor Day (first Monday in September)
- Columbus Day (second Monday in October)
- Veterans Day (November 11)
- Thanksgiving Day (fourth Thursday in November)
- Christmas Day (December 25)
When a federal holiday falls on a Saturday, the preceding Friday is typically observed. When it falls on a Sunday, the following Monday is observed. Holiday delays can extend a 3–5 business day window significantly if holidays fall mid-period.
How 1 Business Day Applies to Common Transactions
The business-day standard affects the timing of nearly all bank transactions. Here are typical processing windows based on Federal Reserve guidelines:
- ACH transfers (standard): 1–3 business days. Same-day ACH is available for eligible transactions submitted before the cutoff. For full ACH timing details, see how long ACH transfers take.
- Domestic wire transfers: Same business day if submitted before the bank's cutoff (often 3:00–5:00 PM ET). After the cutoff, the next business day.
- Mobile check deposits: Typically 1–2 business days. The first $225 of a check is often made available by the next business day under Regulation CC.
- Direct deposit (payroll): Most employers process payroll 1–2 business days before the pay date.
- Credit card payments: Typically posts within 1–3 business days of the payment being received.
Why Business Day Cutoff Times Matter
Each bank sets its own daily cutoff time for processing transactions, within guidelines set by the Federal Reserve. If you initiate a transfer at 5:00 PM and your bank's cutoff is 4:00 PM, that transaction is treated as if it was submitted the following morning — the next business day.
This cutoff effect is most important when timing loan payments, tax payments, payroll deposits, and time-sensitive wire transfers. If a payment deadline falls on a federal holiday or weekend, complete the transaction on the prior business day to avoid a late posting. Knowing how long Zelle takes to process is useful since Zelle transfers may bypass standard ACH delays.
What to Do When a Transaction Is Delayed
If a transfer has not arrived within the expected business-day window, first check whether the delay spans a weekend or federal holiday — those days do not count toward the 1–3 business day estimate. Check your transaction confirmation for an expected arrival date.
If the delay exceeds the stated timeframe, contact your bank with the transaction reference number. For ACH disputes, banks have specific timelines to return erroneous or unauthorized entries under NACHA rules. The CFPB accepts consumer complaints about banking delays and errors at consumerfinance.gov/complaint. For Zelle-specific delays, see how long a Zelle transfer takes for typical processing times.
Frequently Asked Questions
Does Saturday count as a business day for banks?
No — Saturday is not a banking business day under Federal Reserve guidelines. Transactions initiated or submitted on Saturday are generally processed on Monday (assuming Monday is not a federal holiday). Some banks offer limited Saturday hours for customer service, but back-office transaction processing still follows the weekday-only schedule. This is why a 2-business-day transfer initiated Friday may not complete until Tuesday.
Is a business day 24 hours?
No — a business day is a single calendar weekday, not a 24-hour processing window. Most banks have cutoff times between 2:00 PM and 6:00 PM. Transactions submitted after the cutoff are processed the following business day, not 24 hours later.
How many business days are in a typical work week?
A standard work week has 5 business days — Monday through Friday — assuming no federal holidays fall within that week. Weeks containing a federal bank holiday typically have 4 business days for bank processing purposes. For a longer window, see how long 10 business days is in calendar terms.
What time does a business day start and end at banks?
For most transaction processing purposes, a business day begins at midnight and ends at the bank's daily cutoff time, which is typically between 2:00 PM and 6:00 PM local time depending on the institution. Anything submitted after the cutoff is processed the next business day.
Where can I find the Federal Reserve holiday schedule?
The Federal Reserve publishes its annual Reserve Bank holiday schedule at federalreserve.gov. Your bank's website will also list any closures or processing delays around federal holidays.
