The Tube at this hour is a matter of joining the right crowd rather than choosing a seat, and getting through it depends on leaving at a specific minute. This page counts down to 6:31 am precisely — the moment to leave, the moment to touch in, or the moment a meeting on the other side begins.
The figure on this page comes from your own device's clock, checked continuously and recalculated every second against 6:31 am. There is nothing to press and nothing to set up first — the count is already running by the time the page has finished loading, and it keeps going while you are looking at it.
Rail and bus timetables across Britain are printed in 24-hour time, which is why 06:31 is the version that matters when checking a departure against a board or a printed sheet. This page shows 6:31 am for everyday reading and 06:31 alongside it, so the two can be matched without any mental arithmetic.
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 06:31 in the 12-hour clock?
That is 6:31 am, or twenty-nine minutes to seven in the morning 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 6:31 am 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.
