Online alarm clock for 3:40 am
While waiting to collect a parcel from the overnight delivery, you can keep an eye on the clock without repeatedly checking the minutes. An alarm set for 3:40 am marks the appointed moment while leaving a useful buffer before 4:00 am, whether the parcel is at the front door or a nearby collection point.
For this delivery pickup, the alarm needs to be audible despite the phone’s silent setting. A quick sound check at a low volume can confirm whether the browser alert is affected by silent mode or media-volume controls. Keep the page running until 3:40 am and leave the screen awake if necessary. If the browser stops running, the alarm cannot sound, so the delivery collection may be missed even though the time was set correctly.
Moving through the house at 3:40 am can easily disturb anyone sleeping nearby. Keys, shoes and a light jacket can be placed near the exit earlier, reducing the need to open drawers or switch on bright lights. A moderate alarm volume, with the phone close at hand, limits how long it rings. Closing doors gently and avoiding a noisy garage door can also make the late-night collection less disruptive for everyone else at home.
Common questions
Will the alarm still ring if I close the browser tab?
No. The alarm only runs while this tab stays open — closing it, or closing the browser entirely, stops the countdown before it can ring. Keep the tab open in the background if you need it to go off later.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
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.
