Online alarm clock for 3:39 pm
While you watch the clock for your weekend departure, a 3:39 pm alarm marks the moment to leave town rather than letting another small job hold you up. It keeps the agreed time separate from the general rush of packing bags, checking the route and carrying everything to the car. There are 21 minutes until 4:00 pm, enough to finish one last practical task without drifting into a late start.
Your trip depends on hearing the signal amid keys, luggage and conversation, so a quick test beforehand can confirm that the alarm is audible at the volume you expect. After testing, leave the alarm page running and keep the sound available until 3:39 pm. If the browser stops running or the phone goes to sleep, the alarm will not sound, which could delay your weekend drive out of town. A separate phone alarm is sensible when missing the departure would disrupt other people’s plans.
With the afternoon nearly behind you and time on the road ahead, a small snack and some water can fit neatly before departure. A banana, crackers or a filled water bottle is easier to manage now than a full meal that adds washing up and another reason to linger. Coffee can wait if it means an extra stop or slows the final pack; it can be picked up later at a servo when the journey already allows for a break.
Common questions
Do I need to create an account or download anything?
No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.
Can I change the alarm sound?
Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.
What happens once the alarm goes off?
It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
Is this alarm accurate across daylight saving time?
It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.
