How to use the online alarm clock
You are halfway through something, but your 12:22 pm alarm needs to pull you away for a meeting with your tutor at a further-education college. That leaves enough breathing room before 1:00 pm to stop what you are doing, gather any notes or forms and reach the meeting without turning the change of task into a last-minute rush.
A college tutor appointment is easy to miss if the alarm sound has quietly been routed to headphones lying in a bag or on a desk. Before relying on it, check the current audio output and set a volume you will notice from where you are working. Keep the browser running while you wait: if it stops running or the computer goes to sleep, the alarm cannot sound, so it should not be the only reminder for your tutor meeting.
Leaving a task for a midday college meeting can make a full lunch awkward to fit in. A light snack and a drink beforehand may be more practical than starting a meal you must abandon at 12:22 pm; anything hot, messy or slow to finish can wait until afterwards. Put water somewhere visible while you collect your papers, so the shift from your current work to the appointment does not leave it behind.
Common questions
Can I change the sound?
Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
Will it still be right when the clocks change?
Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
Does the alarm still work if I close the tab?
No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.
