Going to bed for a 7:45 am alarm

Asleep by 10:30 pm — 6 full sleep cycles, about 9 hours
Asleep by 12:00 am — 5 full sleep cycles, about 7 hours
Asleep by 1:30 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

You have just woken at 7:45 am, and moving the car from its overnight parking zone is still the first job ahead. The alarm gives you a clear point to get up, find the keys and check where the car needs to go before 8:00 am. That leaves enough room to become properly alert without letting the parking restriction slip your mind.

Because the alarm must wait while you are asleep, leave the browser running on a device that will remain awake until it sounds. Your car reminder cannot ring if the page is closed or the device goes to sleep, so relying on a laptop that powers down overnight could leave the vehicle where it is. Set the volume beforehand and, if possible, keep the device connected to power within hearing distance.

Once the car has been moved, avoid filling the spare morning minutes by accident. At 7:45 am, note the start time of your next commitment and allow for the walk back from the new parking place, making tea or getting dressed. A small buffer after the move keeps this early task from pushing everything else later.

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 7:45 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.
