How to use the online alarm clock
Pack away your flask and blanket as you finish watching the meteor shower above the heath at 1:47 am. Setting the alarm gives you a firm cue to leave, rather than waiting for one more streak and losing track of the night. You can be off the open ground before 2:00 am.
Keep the alarm loud enough to cut through wind, conversation or a nearby car engine while you gather your things. Test the volume briefly and leave the phone within hearing range instead of burying it in a rucksack. Your meteor-shower departure cue will not sound if the browser has been closed or the phone is sleeping, so keep both running until the alert has played.
Coming in from a heath can make a warm car or bedroom feel especially stuffy at this hour. If the air conditioning is running, set a moderate temperature before settling down and avoid placing your phone beside a noisy vent, where the airflow could mask the alarm. Keep some water ready for the journey home after the late-night walk.
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 1:47 am?
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.
