Online alarm clock for 5:03 pm
While you watch the clock for the moment to check whether the windows are shut before the thunderstorm, set the alarm for 5:03 pm and keep your attention on whatever you are doing nearby. The alert gives you a clear cue to inspect each room rather than relying on a glance at the time. With 6:00 pm still ahead, there is also time to secure anything outside once the windows are sorted.
Your windows check may need either a gentle reminder or a sound that cuts through rain, conversation or kitchen noise. Choose a softer tone if you are already listening for the storm and want a discreet prompt; use a more persistent one if you could become distracted. Set the volume before waiting, then test that you can hear it from where you will be. The alarm depends on the browser remaining active, so if it stops running, the windows check will receive no audible reminder.
Waiting for a storm check at 5:03 pm can overlap with an afternoon snack or the start of dinner preparation. A glass of water and something that can be put down quickly are practical while you monitor the sky. Leave hot drinks, messy cooking and anything requiring constant attention until after the windows and outdoor area have been checked.
Common questions
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
