Trial Periods and Cooling-Off Days

Why the last day matters

Free trials, return windows and cooling-off periods all share one feature: after a certain day, the right to cancel or return is gone. A trial that converts to a paid subscription charges you automatically, and a return window that has passed leaves you with the goods. Knowing the exact last day is worth a minute of calculation.

The difficulty is that the rules differ. Some start counting on the day of purchase, some on the day of delivery, and some on the day after. Some include weekends and some move the end to the next working day. Always find the wording that applies to your purchase.

Free trials

A free trial of 30 days that starts on Thursday 22 October 2026 will usually end on Saturday 21 November 2026 if the start day is counted as day 0, or on Friday 20 November 2026 if it is counted as day 1. The terms normally say which. When they do not, assume the shorter period and cancel a day or two early.

Trials often start at a particular time of day, and the cancellation deadline can be set to a time as well as a date. If a service charges at the moment the trial ends, cancel at least a full day before, because time zones and processing delays can bring the charge forward.

A good habit is to put the cancellation date in your calendar the moment you sign up, and to add a reminder two days before it.

Return windows in shops

Shops set their own return windows, commonly 14, 28 or 30 days, and the count normally starts on the day of purchase or the day of delivery. A 28-day window from a purchase on 22 October 2026 runs to 19 November 2026, a Thursday. A 30-day window runs to 21 November 2026, a Saturday.

Check whether the shop counts calendar days, which include weekends, or working days. Most return policies use calendar days. If the last day falls on a weekend and the shop is closed, ask in advance whether the deadline moves.

Also check what has to happen by the last day. In some cases the goods must be back with the shop, and in others it is enough to have notified the shop or posted the parcel.

The 14-day right of withdrawal in the EU

In the European Union, consumers have a right to withdraw from most online and distance purchases within 14 days, without giving a reason. For goods, the period runs from the day you receive them. For services, it runs from the day the contract is concluded, and under the EU rules on time limits the day of the event itself is not counted.

For goods delivered on Thursday 22 October 2026, the 14 days therefore end on Thursday 5 November 2026. If the last day falls on a non-working day, the period is extended to the next working day.

There are exceptions. The right does not apply to goods made to order or personalised, perishable goods, sealed items that have been unsealed for hygiene or media reasons, and tickets or bookings for specific dates, among others. Some countries also give longer periods for doorstep sales, so check the rules where you live.

To use the right, you normally need to tell the trader that you are withdrawing within the period. Keeping a record of the date and of how you informed the trader is sensible, whatever the rule.

Cooling-off rules elsewhere

The idea exists in many countries, with different lengths. In the United States, a federal rule gives buyers three business days to cancel certain sales made at their home or at other places away from the seller’s regular place of business. State laws add others, for example for some contracts for services or memberships.

The point for counting is that business days are used in some rules and calendar days in others. If a rule is in business days, the weekend does not count, and the date you reach is different. Always check the unit.

Counting the days: a short method

1. Find the rule: the length, the start event and the unit, calendar or working days.
2. Take the start date and decide whether that day counts as day 0 or day 1.
3. Add the number of days and note the weekday of the result.
4. If the result falls on a weekend or a holiday, check whether the end moves.
5. Put the date in your calendar and set a reminder before it.

For online purchases, remember that delivery can happen later than the date of the order. The date to use is the one named in the rule, usually delivery for goods, so keep the delivery confirmation.

Using the calculator

On the Add or subtract tab, enter the start date, type the length in days, and read the end date and its weekday. To see both counting conventions, calculate once with the number of days you were given and once with one day fewer.

If the rule is in working days, use the Workdays field instead of Days. The result skips Saturdays and Sundays, and you can add a day for each public holiday that falls in the range.
