Going to bed for a 10:07 am alarm

Asleep by 12:52 am — 6 full sleep cycles, about 9 hours
Asleep by 2:22 am — 5 full sleep cycles, about 7 hours
Asleep by 3:52 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

As your colleague takes over the morning duties, use the 10:07 am alarm as the point to leave for your GP appointment. It gives the handover a clear finish, so a final question or unfinished note does not quietly delay you. If the appointment is later, 11:00 am provides a natural checkpoint for checking your route, paperwork and keys.

Once the handover is agreed, set the alarm and confirm that its sound is distinct from ordinary notifications. Silent mode can prevent an expected alert on some phones, so test the volume before relying on it and keep the page active. Your GP appointment will not be protected if you close the alarm page or allow the phone or computer to sleep, because the browser alarm may then make no sound.

After a shift or an early start, any sleep left beyond 10:07 am needs a firm boundary. Before lying down again, place clothes, travel documents and anything you need for the appointment together, then set a separate alarm for the actual departure time. That preserves the remaining rest without leaving several small tasks to remember when you wake, while a curtain gap can let the late-morning daylight make getting up feel less abrupt.

Common questions

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.

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 10:07 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.
