Counters and branches that close in the late afternoon give no leeway at all, and arriving two minutes late means coming back tomorrow. This page counts down to 3:22 pm precisely, which makes it much easier to judge honestly whether there is enough time left to get there and back.
When the clock reaches 3:22 pm, the count does not sit at zero. It rolls straight over and begins again towards the same time tomorrow, on its own, without a refresh or a reset. That makes this a page worth keeping in a bookmarks bar rather than one you look at once and forget.
Twelve o'clock is where the 12-hour clock is at its weakest, since 12 am and 12 pm are read the wrong way round often enough to cause real trouble. Writing a time as 15:22 removes the problem outright, because a 24-hour figure only ever points at one moment in the day.
Common questions
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 3:22 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 15:22 in the 12-hour clock?
That is 3:22 pm, or twenty-two minutes past three in the afternoon 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.
