The first proper meeting of the day has a way of arriving faster than the morning's admin allows for. Knowing exactly how much time is left before 6:25 am makes the difference between finishing one more thing and starting something you cannot finish. The countdown here updates on its own, second by second.
The count makes no sound and asks for no attention while it runs. It is a number, not an alarm, and nothing goes off when it reaches zero. Leaving the page open in a background tab is perfectly fine — it will carry on counting towards 6:25 am whether or not anyone is watching it.
Plenty of phones, laptops and dashboards default to a 24-hour display regardless of how people around here actually talk, so 06:25 may well be the figure staring back at you even though 6:25 am is how the same moment would be said aloud. Neither is more correct than the other.
Common questions
What happens if 6:25 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.
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 6:25 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.
