Online alarm clock for 3:57 pm
As you finish what you are doing and get ready to leave, set the alarm for 3:57 pm so the reserved books do not remain at the library another day. The alert gives you a clear moment to gather your library card, keys and bag before heading out. With 4:00 pm close by, you can leave promptly without repeatedly checking the clock.
Your trip to collect the books could be delayed if the alarm sound has quietly been routed to headphones you are no longer wearing. Check the audio output after setting the time, then play a brief test sound if you are unsure where it will be heard. Set the volume high enough to notice while packing up. For this library collection, keep the browser page open and your phone or computer awake, because the alarm will not sound after the page is closed or the equipment goes to sleep.
Leaving for the library in the late afternoon can mean stepping from strong air conditioning into lingering outdoor heat. Put any borrowed books in a bag before you go, especially if you may walk or wait for a bus in direct sun. A light layer that was comfortable indoors may feel unnecessary outside, so make it easy to carry rather than wear.
Common questions
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.
Can I use this on a phone?
It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
