Online alarm clock for 10:00 am
While you watch the clock for the moment to take your class on an excursion, set the alarm for 10:00 am so the departure does not get lost among headcounts, bags and last-minute questions. The round hour is easy to tell students and accompanying adults, while the alarm gives you a clear cue to move from waiting to gathering everyone.
Before the class assembles, check where your browser’s audio is being sent. Wireless headphones can stay connected inside a bag or on a desk, making the alert inaudible even when the volume appears high. Play a brief test sound, then disconnect the headphones or keep them where you will hear them. Keep the browser running and the phone awake as well; otherwise no alarm will sound and the class could be left waiting past departure time.
As the morning brightens around 10:00 am, place the screen where glare does not wash out the alarm controls while you supervise the group. Raise the phone rather than bending towards it, use a readable brightness level, and glance at the time only when needed. That leaves your attention on the students and avoids staring into a reflective screen while checking whether the excursion can begin.
Common questions
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.
Does the alarm work if my laptop goes to sleep?
Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.
