Going to bed for a 11:45 am alarm

Asleep by 2:30 am — 6 full sleep cycles, about 9 hours
Asleep by 4:00 am — 5 full sleep cycles, about 7 hours
Asleep by 5:30 am — 4 full sleep cycles, about 6 hours

A sleep cycle runs about 90 minutes, and most people take around 15 minutes to drop off. Waking at the end of a cycle feels easier than waking in the middle of one.

How to use the online alarm clock

Break away from the task in front of you at 11:45 am so there is time to collect your child and make the primary-school drop-off without letting the morning’s work run on. This alarm marks the moment to stop, gather coats, bags and anything needed for the walk or drive. With 12:00 pm approaching, it also creates a clear boundary between the job you are finishing and the school journey.

A school departure can be easy to miss when conversation, a television or kitchen noise covers the alarm. Set the browser’s sound level high enough to be distinct, then test it against the background noise likely to be present at 11:45 am; the computer’s general volume and any muted browser audio can affect what you hear. If the browser is no longer running or the phone has gone to sleep, the signal may not sound, and your child’s primary-school journey could start late.

Before heading to primary school in the late morning, check whether the air outside feels humid as well as whether rain is forecast. A light layer that is comfortable indoors may feel stuffy on a damp walk, while a breezier route can feel cooler. Keep a drink accessible and allow a moment at the door to adjust coats rather than discovering halfway there that everyone is overdressed.

Common questions

Does the alarm still work if I close the tab?

No. Everything runs inside this page, so closing the tab — or quitting the browser altogether — ends the countdown there and then. Leaving it open in the background is all it asks, and switching to another tab makes no difference.

What happens if my laptop goes to sleep before 11:45 am?

The tab sleeps along with it and the alarm will not sound on time, if at all. If you are relying on it, change the power settings so the machine stays awake, or keep a phone alarm running as well.

Do I need an account or an app?

Neither. Choose a time and a sound, press Start, and it runs in this browser tab. Nothing is downloaded, nothing is registered, and closing the page leaves nothing behind on the device.

Can I change the sound?

Yes, there is a short list of tones to pick from before you press Start. Softer sounds are easy to sleep through, so a firmer bell tends to be the safer choice for anything early in the morning.
