How to use the online alarm clock
As you finish the evening’s jobs and head out, a 9:30 pm alarm can mark the moment to check the river level after the downpour. It keeps the inspection from slipping your mind while you put on a waterproof or collect a torch. There is still half an hour before 10:00 pm, leaving a clear window for checking the usual viewpoint and returning home.
Once the river-check alarm is set, the page can sit behind another browser page while you finish getting ready; it should continue counting down and sound at 9:30 pm. Some browsers may limit background activity, however, especially when power-saving settings take over. A river check can therefore be missed if the browser is no longer running or the phone or computer has fallen asleep. Keeping the alarm page available and the sound audible makes its status easier to confirm before leaving.
For a post-downpour walk at this point in the evening, damp air can make the outdoor temperature feel different from the reading shown indoors. A light waterproof layer is useful even if the rain has stopped, and footwear with grip suits wet pavements or muddy paths near the river. Moisture can also mist glasses or a phone screen, so a dry cloth in a pocket helps when reading a gauge or noting the level.
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 9:30 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.
