The FTC 3-day cooling-off rule counts Saturday as a business day, even though Sunday and federal holidays don’t count. This is what makes the FTC 3-day cooling-off rule different from most business-day calculations, where Saturday is treated the same as Sunday. Getting this wrong can cost you your right to cancel a contract before the deadline passes.
The standard calculators on this site exclude both Saturday and Sunday, so they will give you the wrong deadline for this specific rule. Use the worked examples and counting method below instead, or check the Business Days Between Dates calculator only for ordinary Monday-to-Friday deadlines.
What Is the FTC Cooling-Off Rule?
The Cooling-Off Rule is a federal regulation, officially titled the Rule Concerning Cooling-Off Period for Sales Made at Homes or at Certain Other Locations, 16 CFR Part 429, that lets you cancel certain sales for a full refund.It applies to door-to-door sales valued at $25 or more, where the seller fails to disclose your right to cancel within 3 business days of the transaction.
It covers sales made at your home, workplace, or dormitory, and at a seller’s temporary location like a hotel room, convention center, or restaurant, including when you invite a salesperson into your home for a presentation. It does not cover sales completed at the seller’s regular place of business, even if you negotiated the deal somewhere else first.
Does Saturday Count Toward the FTC 3-Day Cooling-Off Rule?
Yes, and this is confirmed directly in the regulation’s own text, not just consumer guidance. 16 CFR 429(f) defines “Business Day” as any calendar day except Sunday or any federal holiday, listing examples like New Year’s Day, Memorial Day, Independence Day, and Christmas Day. Saturday isn’t on that exclusion list, so it counts as a full business day under this specific rule.
The FTC’s own consumer guidance confirms this directly: Saturday is considered a business day, but Sundays and federal holidays are not. This is the reverse of how most everyday business day calculations work, where Saturday and Sunday are both excluded as the weekend. If you’re used to checking does Saturday count as a business day for ordinary deadlines, this federal rule is the specific exception to that general answer, not a confirmation of it.
How to Count Your 3 Business Days
Counting your FTC 3-day cooling-off rule deadline starts the day after the sale, not the sale day itself. Skip Sunday. Skip any federal holiday. Count every other day, including Saturday, until you reach the third one. That date is your deadline, and your cancellation must be postmarked or delivered by midnight on that day.
If the sale happens on a Monday in a week without a federal holiday, you have until midnight on Thursday to cancel. If the sale happens on a Friday with no federal holidays on the following Monday or Tuesday, you have until midnight on Tuesday to cancel.
Here are two fully worked examples using real 2026 dates. If you sign a contract on Friday, June 26, 2026, with no federal holiday in the window, your three business days are Saturday June 27, Monday June 29 (Sunday June 28 is skipped), and Tuesday June 30. Your deadline is midnight Tuesday, June 30, 2026.
If you sign on Friday, September 4, 2026, the following Monday, September 7, is Labor Day, a federal holiday. Your three business days become Saturday September 5, Tuesday September 8 (both Sunday the 6th and Labor Day the 7th are skipped), and Wednesday September 9. Your deadline shifts to midnight Wednesday, September 9, 2026, a full day later than it would be without the holiday.
Why the FTC 3-Day Cooling-Off Rule Differs From a Standard Business Day Calculation?
Most contracts, payment terms, and shipping estimates define a business day as Monday through Friday, excluding both Saturday and Sunday. The calculators on this site, including the Business Days Between Dates and Add Business Days tools, are built around that standard definition, since it’s the one that applies to the vast majority of everyday calculations.
The FTC Cooling-Off Rule uses a narrower exclusion list. It removes Sunday and federal holidays only, leaving Saturday in the count. Plugging cooling-off rule dates into a standard weekday-only calculator will produce a deadline that’s too late, potentially costing you your right to cancel if you rely on it and miss the real date.
This narrower definition isn’t unique to the FTC rule either. The federal Truth in Lending Act’s 3-day rescission right for home equity loans uses the same Saturday-counts, Sunday-and-holidays-don’t convention. This counting method shows up across more than one federal consumer protection rule.
What Sales Does the Cooling-Off Rule Cover?
The rule covers in-person sales made at your home, workplace, or dormitory, or at a seller’s temporary location such as a hotel room, convention center, fairground, or restaurant. It applies even if you’re the one who invited the salesperson into your home.
It does not cover sales for goods or services intended mainly for business use, sales completed entirely by mail or phone with no in-person contact, real estate, insurance, or securities transactions, or emergency repairs you specifically requested. Instruction or training courses are covered regardless of whether you’re taking them for personal or business reasons.
Do State Cooling-Off Laws Give You More Time?
Some states provide their own cancellation rights for specific contract types not covered by the federal rule, including health club memberships, dating services, weight loss programs, and timeshares. If a state cooling-off rule applies and offers a longer period than the federal 3 days, the longer period controls.
These state rules vary significantly and cover different contract types entirely, so check your specific state’s consumer protection office if your situation involves one of these contract categories rather than a standard door-to-door sale.
