Going to bed for a 9:07 am alarm

Asleep by 11:52 pm — 6 full sleep cycles, about 9 hours
Asleep by 1:22 am — 5 full sleep cycles, about 7 hours
Asleep by 2:52 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

Finishing the office evacuation drill at 9:07 am means leaving the assembly point, checking that everyone has been accounted for and getting back inside without losing track of the morning. An alarm set for this time can mark the planned finish, leaving a useful stretch before 10:00 am for returning equipment, signing the attendance sheet and settling at your desk.

With people talking, doors moving and traffic nearby, the alarm signal may disappear into the background. Set the volume while standing where the evacuation drill will end, then test whether the tone remains distinct at that distance; a sound that seems clear beside a desk may be missed outside. Treat the alarm as a supporting cue for the evacuation drill, because it cannot signal the finish if its browser page has been closed or the computer has gone to sleep.

Leaving an assembly point around 9:07 am can involve a sharp change from outdoor daylight to a dim corridor or brightly lit office. Before a future drill, adjust the screen brightness for the place where the alarm will be checked, and keep the display out of direct glare. That makes the time easier to read at a glance while people are moving back into the building.

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 9:07 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.

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.
