Once younger children are finally asleep, this is often the only quiet stretch of the day anyone gets, and it disappears faster than expected. If 10:11 pm is when it has to end, a live countdown gives that stretch an edge rather than letting it drift towards a much later night.
Coming back to this page in an hour, tomorrow or next month shows exactly the same thing: however long is genuinely left until 10:11 pm next comes round. There is no session to lose and nothing to configure again, because the number is worked out fresh each time from the clock on your device.
Rail and bus timetables across Britain are printed in 24-hour time, which is why 22:11 is the version that matters when checking a departure against a board or a printed sheet. This page shows 10:11 pm for everyday reading and 22:11 alongside it, so the two can be matched without any mental arithmetic.
Common questions
Which clock does it use?
Your own. It reads the local time and time zone from the device you are looking at, so the figure reflects where you actually are rather than a fixed zone written into the page.
Will this alert me when the time arrives?
No. It is a live number rather than an alarm — nothing rings, buzzes or notifies you at zero. If you need to be interrupted at 10:11 pm, set an alarm as well and treat this page as the running total.
Is it affected by the clocks changing?
Only in the sense that your device is. When the change between GMT and BST happens at the end of March and October, the device adjusts and the countdown follows it without anything to do here.
What is 22:11 in the 12-hour clock?
That is 10:11 pm, or eleven minutes past ten at night if you are saying it aloud. From 13:00 onwards, subtracting twelve gives the pm figure — the same moment written three different ways.
