Online alarm clock for 3:21 pm
You are handing the job to the next person, checking that the loose ends are covered, and waiting for the moment you can clock off. An alarm for 3:21 pm can mark the final check-in without letting the handover drift towards 4:00 pm. It gives you a clear cue to record your finish and leave rather than watching the clock.
Your shift may end in a workshop, kitchen, warehouse or other space where voices and machinery can drown out a browser alarm. Set the volume high enough to rise above the usual background noise, then test it before relying on it. Keep the browser running and the screen awake: if either stops, the shift reminder will not sound, which could leave you working past your finish. A phone vibration can provide a discreet secondary cue where noise levels change.
If other people are at home during the afternoon, place the phone or computer close to you instead of turning the alarm up across the whole house. At 3:21 pm, someone may be studying, working remotely or settling a child, so a nearby moderate signal is less disruptive. Once you have clocked off and completed the handover, silence the alarm promptly rather than letting it repeat while you pack up.
Common questions
Can I use this on my phone instead of a laptop?
Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
Can I set more than one alarm at a time?
This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
Why use a browser alarm instead of my phone's built-in one?
Mainly for reliability against silent mode, do-not-disturb, or a phone left charging out of earshot. It's a useful backup or a desk-based alternative, though it depends on this tab staying open rather than running in the background of your phone.
Is there a cost to use this?
No, it's free, with no sign-up and no limit on how many times you set it. It just needs the tab left open until the time you've chosen arrives.
