Going to bed for a 8:54 am alarm

Asleep by 11:39 pm — 6 full sleep cycles, about 9 hours
Asleep by 1:09 am — 5 full sleep cycles, about 7 hours
Asleep by 2:39 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 have only just woken, and getting out for rowing training on the Thames still means leaving the bed, dressing and gathering your kit. An alarm set for 8:54 am gives you a clear moment to start, with 9:00 am close enough to serve as the point when you should be moving rather than still deciding what to take.

Before heading towards the Thames, set the alarm and leave the sound at a level you will notice while pulling on layers or packing a water bottle. Keep the alarm page active and your phone awake until it rings; otherwise the rowing reminder may stay silent and your departure can slip. If the phone usually dims quickly, connect it to power and adjust its sleep setting before relying on this alert.

Once an 8:54 am rowing alarm sounds, any sleep left in the morning is likely to come from drifting back under the duvet rather than planned rest. Put your clothes and kit beyond arm’s reach before bed, then stand up to silence the alarm. Opening the curtains straight afterwards gives this early start a firm boundary and makes 9:00 am the beginning of your preparations, not another chance to doze.

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 8:54 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.
