Online alarm clock for 4:43 am
Handing the airport pickup to someone else at 4:43 am means passing on more than the car keys: give them the flight number, terminal and meeting point before you stand down. Setting the alarm now leaves a clear prompt before 5:00 am, so the changeover does not rely on either person remembering a late-night conversation.
With the pickup handed over, the alarm page may sit behind flight tracking or maps while the replacement driver checks arrival details. Keep the browser running and return to the alarm page before locking the phone, as mobile browsers can pause work left in the background. Do not make this the only safeguard for the airport pickup: if its page is closed or the phone sleeps, the alarm cannot sound. A separate phone alarm gives the new driver a useful backup.
Before the replacement driver settles down again, arrange a gentle light near their keys and shoes, then leave the main room dark. At 4:43 am, a bright ceiling light can feel abrupt, while no light at all makes it harder to gather a wallet, licence and jacket. A dim lamp switched on beforehand creates a visible path out without lighting the whole house.
Common questions
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.
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.
