Going to bed for a 9:34 am alarm

Asleep by 12:19 am — 6 full sleep cycles, about 9 hours
Asleep by 1:49 am — 5 full sleep cycles, about 7 hours
Asleep by 3:19 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

While getting ready for a vaccination at your local pharmacy, set the alarm for 9:34 am before gathering your appointment details, keys and anything else you need. That leaves a clear prompt during the morning rather than relying on a hurried glance at the clock. With 10:00 am approaching, you can use the remaining time to check the pharmacy address and prepare to leave without turning the whole morning into a countdown.

Your vaccination plans depend on the alert remaining active, so keep this page in the foreground where possible. Browsers may reduce activity on a page sent into the background, particularly when another app or page has held your attention for a while. Check that the alarm is still visible and that your sound is audible. If the browser is closed or the phone goes to sleep, the vaccination reminder may never sound, so use a separate phone alarm when missing 9:34 am would disrupt the appointment.

Before heading to the pharmacy in the morning light, lower harsh screen brightness if the display feels glaring, but keep it bright enough to read the alarm status at a glance. Position the phone away from direct window reflections and increase text size instead of bringing the screen close to your eyes. Once the 9:34 am alert sounds, dismiss it deliberately so there is no doubt that you noticed it.

Common questions

Will it still be right when the clocks change?

Yes. It reads your device's local clock, so the move between GMT and BST at the end of March and October is picked up automatically, as long as the computer's date, time and time zone are set correctly.

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 9:34 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.
