Online alarm clock for 3:13 am
As your hospital night shift winds down, hand over the last details and set the 3:13 am alarm for the point when you need to wrap up. It gives you a clear marker before 4:00 am, so the final notes, keys or equipment can pass to the next person without repeatedly checking the clock.
Before the handover becomes busy, choose 3:13 am and test the sound at a low volume, then raise it enough to hear over the usual overnight background noise. Keep this browser active and mains power connected after the check. If it is closed or the computer falls asleep, the hospital shift may reach its handover point without the alarm sounding, so use a separate alarm as backup when timing cannot slip.
Once the next person has taken over, avoid letting small unfinished tasks stretch the night towards 4:00 am. Note anything that can wait, gather what you need for the trip home, and keep the transition brief. Protecting the sleep left after 3:13 am may be easier when breakfast, curtains and a phone charger are ready before the shift, leaving fewer jobs between arriving home and settling down.
Common questions
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.
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.
