The hour after the flat finally goes quiet is the one most people would keep if they could, and it is also the one that vanishes without being noticed. Giving it an end at 11:22 pm and watching the figure fall is a fairer account of it than looking up later and doing the subtraction.
The count runs entirely inside the browser, which is why it needs no account, no permission and no connection once the page has loaded. It also means the figure belongs to this tab: close the page and it stops, and opening it again starts the calculation from scratch rather than resuming.
In an office where a dozen nationalities read the same calendar invite, 24-hour notation quietly does a lot of work. 23:22 cannot be misread as the other end of the day, whereas 11:22 pm depends on the reader noticing two small letters at the end of it. Both describe exactly the same moment.
Common questions
What happens once 11:22 pm has passed for today?
The count rolls over and carries on towards the same time tomorrow. That happens on its own at the moment the time passes — the page does not need reloading and there is nothing to reset by hand.
Which clock does the countdown use?
Your own. It reads the local time and time zone from the device in front of you, which in the Emirates means Gulf Standard Time, UTC+4. Travel and the count follows whatever the device picks up.
Will it alert me when 11:22 pm arrives?
No. This is a live figure rather than an alarm — nothing sounds, vibrates or notifies at zero. If you need interrupting at 11:22 pm, set an alarm alongside it and use this page as the running total.
Do the clocks change here?
No. The UAE has no daylight saving at all, so the offset stays at UTC+4 in every month. When the gap to Europe or North America shifts, it is their clocks that moved, not yours.
