Coursework due at midnight has ended more evenings than any alarm ever has, and the last hour before a deadline is when the exact figure matters most. This page tracks the time remaining until 10:05 pm down to the second, rather than rounding it into something more comfortable.
Coming back to this page in an hour, tomorrow or next month shows exactly the same thing: however long is genuinely left until 10:05 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.
Writing a time as 10:05 pm keeps the am or pm attached, which reads naturally in a sentence but is easy to skim past in a long list of similar entries. Writing it as 22:05 is less conversational and considerably harder to misread, which is why schedules and rotas lean that way.
Common questions
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 22:05 in the 12-hour clock?
That is 10:05 pm, or five 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.
Does the number update by itself?
Yes. It recalculates every second from your device's clock, so there is nothing to refresh or restart. Whatever is on screen is the current gap to the target time, not a figure worked out when the page first loaded.
What happens if 10:05 pm has already gone for today?
The count simply carries on towards the next occurrence, which is tomorrow. That rollover happens on its own — the page does not need reloading and there is nothing to reset by hand.
