Do Business Days Include Saturday? What Counts and When It Doesn't

Short answer: in the United States, Saturday is usually not a business day. The standard business week runs Monday through Friday, and most delivery estimates, bank holds, and contract deadlines that say "business days" skip Saturday and Sunday entirely.

That said, "usually" is doing real work in that sentence. Whether Saturday counts depends on who is doing the counting. USPS delivers on Saturday. Some federal consumer-lending rules treat Saturday as a full business day. A contract can define the term however the parties want. If you are trying to work out when a package, a refund, or a deadline actually lands, the context matters more than the general rule.

This guide covers the default definition, then walks through the situations where Saturday does and does not count, so you can apply the right rule to your case.

The standard definition of a business day

A business day is a day when normal business operations take place. In the US and most Western countries, that means Monday through Friday, excluding public holidays. Saturday and Sunday are treated as non-business days even though plenty of shops, restaurants, and warehouses are open.

The distinction that trips people up is between a business day and a working day:

• A business day is a calendar convention. It exists so that deadlines and timelines can be counted consistently.
• A working day is whatever day a particular person or company is actually working.

A retail employee who works Saturday has a working day on Saturday. That does not turn Saturday into a business day for the purpose of a "5 business days" shipping estimate or a bank deposit hold.

Quick counting examples

Using the Monday to Friday convention:

| You start counting on | 1 business day later | 3 business days later | 5 business days later | | --- | --- | --- | --- | | Monday | Tuesday | Thursday | Next Monday | | Wednesday | Thursday | Next Monday | Next Wednesday | | Friday | Next Monday | Next Wednesday | Next Friday |

Notice that "3 business days" from Wednesday is the following Monday, not Saturday. The weekend is simply skipped. Public holidays that fall on weekdays get skipped in the same way, which is why a five-business-day window around Thanksgiving or Christmas can stretch to more than a calendar week. If you need to work out the exact landing date for a specific pair of dates, WeekLeft's weeks between dates calculator handles the arithmetic once you know whether weekends count.

Is Saturday a business day for shipping?

This is where most people run into the question, and the answer depends on the carrier and the service level.

USPS

The Postal Service is the main exception to the Monday-to-Friday rule. USPS delivers mail and packages Monday through Saturday as part of its regular schedule, with no Saturday surcharge on standard services such as First-Class Mail, USPS Ground Advantage, Priority Mail, and Priority Mail Express. In practice, USPS treats Saturday as a normal delivery day, so a two-day Priority Mail estimate on a Thursday shipment can mean Saturday arrival rather than Monday.

Sunday is different. Regular USPS mail does not move on Sunday. Priority Mail Express is the only standard service that offers Sunday delivery, and it carries an extra charge.

UPS

UPS splits Saturday by address type and service:

• Residential UPS Ground packages are delivered on Saturday in many metro areas at no extra cost.
• Commercial (business address) Ground deliveries run Monday through Friday.
• UPS Air services (Next Day Air, 2nd Day Air) deliver on Saturday only if the shipper selected and paid for Saturday Delivery when creating the label.

Even where a package physically arrives on a Saturday, UPS still calculates most guaranteed delivery windows on a Monday-to-Friday basis. If you ship a 3-day service on Wednesday, the committed delivery date is Monday, not Saturday, unless a Saturday option was selected.

FedEx

FedEx follows a similar pattern. FedEx Home Delivery, the residential ground service, delivers every day of the week including Saturday and Sunday in most of the country, with no weekend surcharge. FedEx Ground, which serves commercial addresses, runs Monday through Friday. FedEx Express (overnight and 2Day) offers Saturday delivery as a paid option the shipper must choose at booking.

Carrier summary

| Carrier | Saturday delivery on standard residential service | Saturday counted in transit estimate | Sunday delivery | | --- | --- | --- | --- | | USPS | Yes, no surcharge | Yes, Saturday is a regular delivery day | Priority Mail Express only, extra fee | | UPS | Yes for residential Ground in many areas; paid option for Air | Generally no for guaranteed services | Limited, select areas | | FedEx | Yes for Home Delivery; paid option for Express | Home Delivery includes weekends; Ground and Express do not | Yes for Home Delivery in most areas |

Two practical takeaways:

1. When a retailer quotes "ships in 3 to 5 business days," that window almost always refers to processing and transit on weekdays only. Do not expect a Saturday arrival unless the carrier and service are known.
2. The tracking page is the source of truth for your specific package. The estimated delivery date already accounts for whether Saturday is in play for that service and ZIP code.

Is Saturday a business day for banks?

No. For US banks, Saturday is never a business day, even if the branch is open.

This comes from Regulation CC, the federal rule that governs how quickly banks must make deposited funds available. Regulation CC defines a business day as every calendar day except Saturday, Sunday, and the federal holidays it lists. A "banking day" is a business day on which the bank is open for substantially all of its functions. Since Saturday is never a business day under the rule, it can never be a banking day either.

The Federal Reserve's own compliance examples make this concrete: a check deposited with a teller on Saturday is treated as received on Monday, the next banking day. Funds subject to next-day availability then become available on Tuesday.

This is why:

• A deposit made Saturday morning often shows as pending until Monday.
• A transfer initiated on Friday evening may not settle until Tuesday or later.
• Bank hold notices that say "second business day" skip weekends and federal holidays entirely.

Card payments and instant transfer services can move money on weekends, but the underlying settlement between banks still follows the business-day calendar.

Is Saturday a business day in contracts and legal deadlines?

Here the honest answer is: check the document.

Contracts

Most commercial contracts define "Business Day" explicitly, and the overwhelmingly common definition is any day other than a Saturday, Sunday, or a day on which banks in a named city are closed. Some contracts also extend any deadline that lands on a weekend to the next business day. If a contract does not define the term, courts typically fall back on the ordinary Monday-to-Friday meaning.

Some agreements use different language on purpose. Collective bargaining agreements, retail leases, and service contracts in six-day industries occasionally define business days to include Saturday. Read the definitions section before you count.

Federal court deadlines

The Federal Rules of Civil Procedure use their own method. Under Rule 6(a), when a period is stated in days, you count every day, including intermediate Saturdays, Sundays, and legal holidays. The weekend only matters at the end: if the last day of the period falls on a Saturday, Sunday, or legal holiday, the deadline rolls forward to the next day that is none of those. So a 14-day period runs across weekends in the middle, but it will never expire on a Saturday.

Consumer lending: the exception where Saturday counts

Regulation Z, the federal Truth in Lending rule, has two definitions of business day, and one of them includes Saturday.

The general definition is a day on which the creditor's offices are open to the public for substantially all business functions. For most lenders that means Monday through Friday.

For a specific set of mortgage disclosures and the right of rescission, though, Regulation Z defines a business day as all calendar days except Sundays and the federal holidays listed in 5 U.S.C. 6103(a). Under that definition, Saturday counts. If you close a home refinance on a Wednesday, the three-business-day rescission period includes Saturday, and it ends at midnight on that Saturday rather than the following Monday. The same Saturday-inclusive rule applies to the waiting periods for Loan Estimate and Closing Disclosure timing.

This matters if you are counting a mortgage waiting period or trying to cancel a home equity loan. The lender's disclosure should state the exact expiration date, and it is worth checking that date rather than assuming weekends are excluded.

Is Saturday a business day in other countries?

The Monday-to-Friday convention is not universal.

• Six-day work weeks. In several South Asian countries, and in specific industries elsewhere, Monday through Saturday is the standard working week, with Sunday as the only weekly day off. Businesses operating on that schedule may count Saturday as a business day in their own timelines.
• Friday and Saturday weekends. Many countries in the Middle East, including Saudi Arabia, the UAE, and Qatar, run Sunday through Thursday, with Friday and Saturday as the weekend. In those markets Saturday is clearly not a business day, but neither is Friday.
• Europe, Canada, Australia. Monday through Friday is standard, with national and regional public holidays layered on top.

For international shipping or cross-border payments, the transit estimate may combine the business-day calendars of both countries, and customs processing adds its own delays. A "5 business day" international estimate is best treated as a floor rather than a promise.

How to check whether Saturday counts in your situation

Rather than guessing, use this sequence:

1. Look for a definition. Contracts, terms of service, bank disclosures, and carrier service guides almost always define "business day." That definition wins.
2. Identify the counter. A bank, a court, a carrier, and a retailer each apply a different rule. Match the rule to the party that set the deadline.
3. Default to Monday through Friday. If nothing is specified and you are in the US, assume Saturday and Sunday do not count and that federal holidays are also excluded. For a month-by-month breakdown of exactly how many weekdays and holidays that leaves, see our business days in a month tables.
4. Confirm with the source. For a package, check tracking. For a deposit, check the hold notice. For a legal deadline, read the rule or ask the clerk.

Frequently Asked Questions

Is Saturday considered a business day in the USA? Generally no. The US business week is Monday through Friday, and most shipping estimates, bank processing timelines, and contract deadlines exclude Saturday and Sunday. The main exceptions are USPS delivery, residential ground delivery from UPS and FedEx, and certain federal mortgage disclosure rules that count Saturday.

If something says "1 business day," does that include Saturday? Not usually. One business day from Friday is Monday. One business day from Saturday is also Monday, because the count does not start until the next business day begins.

Does "3 to 5 business days" include weekends? No. Three to five business days means three to five weekdays, excluding public holidays. From a Monday, that is Thursday through the following Monday. From a Thursday, it is the following Tuesday through Thursday.

Is Saturday a business day for Amazon or online orders? Retailers typically quote processing time in business days (weekdays), but the delivery itself may happen on Saturday if the carrier delivers to residential addresses on weekends. The order page or tracking link will show the actual estimated arrival date.

Do banks count Saturday as a business day if the branch is open? No. Under Regulation CC, Saturday is never a business day regardless of whether the branch is open. Deposits made on Saturday are treated as received on the next banking day, normally Monday.

Does Saturday count toward a mortgage rescission period? Yes. For rescission and certain mortgage disclosure timing under Regulation Z, business days include Saturday and exclude only Sundays and federal holidays.

Is Sunday ever a business day? Almost never in the US. Even the rules that include Saturday, such as the Regulation Z rescission definition, still exclude Sunday. Sunday deliveries from USPS Priority Mail Express or FedEx Home Delivery are a delivery service, not a change to the business-day calendar.
