Going to bed for a 7:13 am alarm

Asleep by 9:58 pm — 6 full sleep cycles, about 9 hours
Asleep by 11:28 pm — 5 full sleep cycles, about 7 hours
Asleep by 12:58 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

You are only just waking at 7:13 am, before the uniforms, breakfast and school-bus preparations have begun. Setting the alarm now gives the morning a clear marker while you gather your thoughts and decide what needs doing first. With 8:00 am approaching, there is still room to get your child ready without treating every small task as an emergency.

Before relying on the alarm, play a quick test signal and check that its volume is easy to hear from where you will be helping your child. This avoids discovering too late that the sound is muted or lost beneath the usual morning noise. Because a browser alarm cannot sound after its page stops running or the computer goes to sleep, keep it active or use a separate backup so the school bus is not missed.

As you move from bed to breakfast at this early hour, make the changing light work for the routine. Open the curtains before laying out clothes, but switch on a nearby lamp if the British morning is still grey, especially around the stairs or hallway. Preparing that light now makes bags, shoes and PE kit easier to spot when the alarm sounds and everyone starts moving.

Common questions

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.

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

Can I use this on a phone?

It works in a mobile browser, but phones lock the screen and suspend background tabs far more readily than a laptop does, which can stop the alarm sounding. For anything important, a desktop or a plugged-in laptop is the steadier option.
