Online alarm clock for 7:21 pm
You are finishing what you are doing and heading out to collect your teenager from Army Cadets, so set the alarm for 7:21 pm before you leave. It gives you a clear cue to pick up your keys and start the journey rather than noticing the time when 8:00 pm is already close. Keep the volume high enough to hear over the ordinary bustle of getting out of the house.
Your Army Cadets collection depends on hearing the signal, so test it now while there is still time to correct the sound level. Set a temporary alarm for the next minute and listen for it from wherever you will be waiting. This browser alarm cannot alert you if its page has been closed or your phone has gone to sleep, which could leave you late for the club collection; keep the page open and the phone awake until 7:21 pm.
Leaving for an Army Cadets pick-up during the evening can mean stepping from a bright room into a much darker street. Before 7:21 pm, switch on the outside light if you have one, and put your keys beside a small torch or a charged phone. That preparation makes the doorstep, path and parked car easier to see when the alarm sounds and you need to head off promptly.
Common questions
What happens if my laptop goes to sleep before 7:21 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.
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.
