Affiliate disclosure. The partner link in the masthead and in the band beside the copy on this page is a sponsored link to a partner operator, and this site may be paid if you open an account through it, at no extra cost to you. It carries rel="sponsored noopener" and opens in a new tab. The subject of this desk is the clock an account runs on, so its own interest is stated here rather than left for a footer: one link funds the site, and no operator, game or regulator is named, rated or recommended anywhere on it.

The window a promotion is open for

An offer is advertised with one time and governed by three. It opens at an instant, it is scheduled to close at another, and it can close early the moment an allocation or a pool is exhausted. Only one of those three is usually printed where the reader meets the offer.

the boundaryThe instant the account's day is measured from. On the samples it is 00:00 UTC, which is a different wall-clock moment for every reader.
the countdownWhat a window is measured from and whether day one counts. A window advertised as 30 days delivers 29 days 23 hours 59 minutes on the sample.
the calendarThe working-day clock money moves on, with its cut-off, its weekends and its holidays. One working day covered 87 hours 30 minutes on the sample.
Direct answerA promotion is governed by three times: the instant it opens, the instant it is scheduled to close, and the instant its allocation or pool is exhausted, which can be earlier than the stated close and is what "while stocks last" means. A window stated in the operator's zone is a different wall-clock window for every reader.

Three times, one advertisement

the open
The first instant a claim is accepted. Claims before it are refused, and a claim placed a second early is refused for the same reason a bet placed after a cut-off is refused. On the sample it is Monday 00:00 UTC.
the stated close
The last instant a claim is accepted if nothing else intervenes. On the sample, Sunday 23:59 UTC, which is 7 days minus one minute of elapsed window because both ends are stated inclusively.
the actual close
An allocation exhausted, a pool won or a budget spent. This is the time that matters and the one that is not printed, because it cannot be known in advance. On the sample the allocation is a quantity and not a time, so the close moves.
Why an allocation closes the window earlya bonus pool of 50,000.00 a credit of 25.00 per claimant claims available 50,000.00 / 25.00 = 2,000 if claims arrive at 40 an hour, the pool lasts 2,000 / 40 = 50 h stated window 7 d 00 h = 168 h so the pool is exhausted on day 2.1 of a 7-day window the advert says seven days the arithmetic says two, for every claimant after the 2,000th

What to look for in an offer window

What this page does not cover. The conditions attached to the credit, the requirement to be staked and what each game contributes belong to the bonus-terms desk (cycle 8). The rules about what an advertiser may claim and how the small print must travel with it belong to the advertising desk (cycle 47). This page is only the window and the clock it is stated on.
