Split shifts in care work and hospitality carve the middle of the day into two halves with a gap between them, and the return time is usually exact. If that time is 12:55 pm, this page tracks the wait precisely, second by second, without anything to set up or press first.
Coming back to this page in an hour, tomorrow or next month shows exactly the same thing: however long is genuinely left until 12:55 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.
Between the last Sunday in March and the last Sunday in October the country runs on BST rather than GMT, which is why timetables and confirmations sometimes carry the label as well as the number. This page counts down to 12:55 pm using whatever your device is currently set to, so the switch is handled for you.
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 12:55 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 12:55 in the 12-hour clock?
That is 12:55 pm, or five to one 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.
