How to use the online alarm clock

Waking at 6:08 pm for an NHS blood donation means getting your bearings before anything else: check the appointment time, find your paperwork and allow for the journey. The alarm marks the moment to begin that routine, with 7:00 pm serving as a useful final checkpoint rather than the time to start preparing.

Your departure depends on hearing the signal, so set the alarm volume above whatever is playing nearby and test it once from where you are resting. Television, music, a running shower or street noise through an open window can mask a browser alarm more easily than expected. Your NHS blood donation could be missed because this alarm can sound only while its page remains open and your phone or computer stays awake. Keep the screen active and use another alarm as backup if the appointment leaves little room for delay.

As you prepare for an evening appointment, check the NHS instructions you were given before choosing food or drink. Follow any directions specific to your blood donation, and leave anything uncertain until you have confirmed it. Put an allowed drink or snack beside your keys if appropriate, so it is not forgotten while you gather the rest of what you need.

Common questions

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.

What happens if my laptop goes to sleep before 6:08 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.
