Online alarm clock for 2:10 am
As you finish packing your torch, notebook and water, a 2:10 am alarm marks the moment to leave for a night count of nesting sea turtles. Setting it now gives you a clear departure cue while the beach is still dark, rather than relying on another glance at the clock. You will be well underway before 3:00 am.
Your departure surroundings should shape the alarm tone. A gentle sound may suit a quiet field station where other people are sleeping, while a more persistent tone makes sense if you are likely to be outside, loading equipment or wearing headphones. Check that the volume matches where you expect to be at 2:10 am. The alarm depends on an active browser and an awake phone; otherwise it may stay silent and delay the nesting turtle count.
Before leaving, keep the screen dim and use a warm display setting if your phone offers one. Bright light can feel harsh against a dark room, vehicle or beach access track, so place the phone where the alarm remains audible without keeping the display in view. After checking the time and route, turning the screen face down reduces stray light while you gather the final items.
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.
