Going to bed for a 5:58 am alarm

Asleep by 8:43 pm — 6 full sleep cycles, about 9 hours
Asleep by 10:13 pm — 5 full sleep cycles, about 7 hours
Asleep by 11:43 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 5:58 am

While you watch the clock and wait to gather the mail for a remote delivery route, a 5:58 am alarm gives you a precise cue without sending you out early. The timing leaves a brief window to check the satchels, keys and run sheet before 6:00 am, when the depot or roadside handover may begin.

Because this alarm is running in your browser, you can leave its page visible while you monitor the time. If you switch to another tab, keep the alarm page open and make sure your browser is still allowed to play sound; a background page may be muted or suspended by browser settings. The alarm cannot signal the start of your delivery route if its page has been closed or the computer or phone has gone to sleep, so use a separate alarm when you cannot keep it active.

If gathering the mail is only a quick early-morning task and you intend to sleep again afterwards, prepare the route bags and clothing beforehand. Keep the return to bed simple by placing anything needed at 5:58 am near the door, using only enough light to identify labels, and deciding in advance whether the alarm should be dismissed or left available for a later cue.

Common questions

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

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.
