Going to bed for a 5:28 am alarm

Asleep by 8:13 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:43 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:13 pm — 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.

Online alarm clock for 5:28 am

As you hand the shift to a colleague, a 5:28 am alarm keeps the morning call with Asia from disappearing between final notes and sign-off. With only an hour or two separating your working times, the other side may already be settling into its day. The alarm leaves space to finish the handover before 6:00 am without relying on a glance at the clock.

For this call, the useful check happens before anyone needs the signal: set 5:28 am, test the sound, and confirm that the volume is clearly audible from where you will complete the handover. A quiet test now also reveals whether headphones are taking the audio. If the browser session ends or the computer sleeps, the alarm cannot cover the Asia call, so another reminder should back it up if you may step away.

Before an early handover, keep food simple enough that preparation does not compete with the call. Water or a ready-made drink can sit beside your notes, while anything needing cooking can wait until the conversation is finished. If breakfast is already prepared, a small portion before 5:28 am avoids juggling a plate while passing on details; the rest can follow after 6:00 am, when the immediate responsibility has moved on.

Common questions

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.

Is this alarm accurate across daylight saving time?

It uses your device's local clock, so as long as your computer's time and date settings are correct, it'll adjust automatically when daylight saving time starts or ends.

Can I use this on my phone instead of a laptop?

Yes, it works in a mobile browser the same way, but phones are more likely to lock the screen or sleep, which can stop the alarm from ringing. A laptop or desktop tends to be more reliable for this.
