Countdown to 3:03 am according to your device's time.

 
 

The shipping forecast at twenty past five is one of the few fixed points anyone awake at this hour can set their watch by, and it has been read at more or less the same times for decades. If 3:03 am matters to you in the same way, this page tracks the exact wait until it comes round again.

There is one number to read and nothing to choose: hours, minutes and seconds counting down together towards 3:03 am. No start button, no options, no settings page to get right beforehand — just the current gap to that time, updating on its own for as long as you need it.

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 3:03 am using whatever your device is currently set to, so the switch is handled for you.

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 3:03 am, 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 03:03 in the 12-hour clock?

That is 3:03 am, or three minutes past three 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.
