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.

Online alarm clock for 7:13 am

As you hand the school-bus routine to another adult, set the alarm for 7:13 am so the changeover has a clear starting point. Mention what is already packed, what the child still needs, and when they should leave. That keeps the remaining preparations moving without turning 8:00 am into an accidental deadline.

For the adult taking over, the alarm is most useful when the browser stays active and the sound is tested before attention shifts to breakfast, bags or shoes. A sleeping phone or closed browser can leave the school-bus handover without an alert, so use a device that will remain awake until 7:13 am. Keep its volume high enough to be heard from the room where the morning tasks are happening.

Once the child is ready, work backwards from the walk or drive to the pickup point rather than relying on the usual journey time. Roads near British schools can become busier as drop-off traffic builds, while a missed pedestrian crossing may add another wait. At this early hour, allow a small margin for traffic, finding a safe place to stop, and walking the final stretch without rushing.

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.
