How to use the online alarm clock

You have just woken at 4:39 pm and still need to make the final appointment at your bank branch. Before getting up, check the closing time and allow for the journey, as waiting until 5:00 pm may leave no room for delays. Set the alarm for the point when you must be dressed and heading out, rather than for the branch’s closing time.

Missing that bank appointment could mean returning on another working day, so make sure the alert can actually be heard. Raise the media volume, switch off silent mode and play a brief test sound before relying on it. Keep the alarm page open and the phone awake; otherwise, the reminder for your bank appointment will not sound and you could lose the remaining travel time.

A rushed departure late in the afternoon can disturb other people at home, particularly if they are working, resting or preparing tea. Put your clothes, keys, bank documents and travel card together quietly before the alarm goes off. Choose a clear tone at moderate volume, keep the phone beside you, and tell anyone nearby that you may need to leave promptly when it sounds.

Common questions

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.

What happens if my laptop goes to sleep before 4:39 pm?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.

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.
