How to use the online alarm clock
Breaking off halfway through a task is easier when 1:40 pm has a clear purpose: it is the moment to stop, gather your documents and get ready for a passport-office appointment. Setting the alarm now creates a firm boundary around whatever you are finishing. That still leaves a useful margin before 2:00 pm for putting papers away, checking you have your passport photos and leaving without a last-minute scramble.
For a passport-office appointment, choose an alarm sound that matches where you are working. A softer tone may be enough in a quiet room, while a more insistent sound can cut through conversation or household noise. Set the volume accordingly, then keep the alarm page active while you continue. If the browser is no longer running or the phone goes to sleep, the alarm cannot interrupt your work, which could make you late for the passport-office appointment.
Before settling back into the job, check the midday journey rather than relying on the usual travel time. Lunchtime traffic, roadworks or a missed bus can use up the margin before an appointment. Work backwards from the arrival time, include a few minutes for finding the entrance and security checks, and let the 1:40 pm alarm mark the point when work ends and the journey begins.
Common questions
What happens if my laptop goes to sleep before 1:40 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.
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.
