The pips on the hour have been marking time for the best part of a century, and plenty of people still set their watch by the one o'clock signal without thinking about it. This page does something narrower and more exact: it counts down to 1:33 pm on your own device's clock, right down to the second.
When the clock reaches 1:33 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.
Said out loud, 1:33 pm usually comes out as twenty-seven minutes to two in the afternoon rather than as a string of digits. Spoken and written time diverge more than people expect, which is worth remembering when somebody tells you a time over the phone and you are trying to match it against something printed.
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 1:33 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 13:33 in the 12-hour clock?
That is 1:33 pm, or twenty-seven minutes to two 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.
