Going to bed for a 9:38 am alarm

Asleep by 12:23 am — 6 full sleep cycles, about 9 hours
Asleep by 1:53 am — 5 full sleep cycles, about 7 hours
Asleep by 3:23 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

Breaking away from what you are doing for a vaccination at the local pharmacy is easier when 9:38 am has a clear stopping point. An alarm at this time can mark the moment to gather your appointment details, keys and coat, leaving the remaining part of the morning uncluttered. If the appointment is closer to 10:00 am, the alert also creates a useful margin for the journey and any queue at the counter.

Your pharmacy visit depends on hearing the alert, so the browser needs to remain open and the computer or phone awake until it sounds. Closing the browser or letting the phone sleep may mean the alarm never signals your departure. The displayed time offers a quick check that 9:38 am is selected, while the alarm sound should be audible above whatever currently has your attention.

The journey to the pharmacy may feel different from an earlier morning trip because humidity can make the air seem close even when the temperature looks mild. A light outer layer that is easy to remove suits a short walk, and checking for drizzle before leaving can prevent an uncomfortable wait outside. With 22 minutes until 10:00 am, there is still room to adjust clothing without turning the departure into a rush.

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 9:38 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.
