Going to bed for a 4:48 am alarm

Asleep by 7:33 pm — 6 full sleep cycles, about 9 hours
Asleep by 9:03 pm — 5 full sleep cycles, about 7 hours
Asleep by 10:33 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 4:48 am

You’re waking at 4:48 am with the overnight delivery pickup still ahead of you, so the first job is simply getting alert enough to leave. There are 12 minutes before 5:00 am, enough time to sit up, check the pickup details and gather your keys without turning the departure into a scramble.

Headphones left paired from earlier can quietly receive the alarm while the room stays silent, which is risky when a parcel is waiting elsewhere. Checking where the audio will play helps avoid that surprise; using the phone speaker and a clearly audible volume is more suitable if the headphones are not being worn. The delivery pickup could also be missed if this page is no longer running or the phone powers down before the alarm time, so a separate built-in alarm provides useful backup.

Once the parcel has been collected, the remaining night can still be treated as sleep time rather than the start of the day. Keep the return home low-key: dim the dashboard and indoor lights, leave non-urgent messages until later, and prepare the bed before departing. At 4:48 am, that small bit of preparation reduces the amount of activity waiting after the drive and makes it easier to settle back into the sleep that remains.

Common questions

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.

Can I set more than one alarm at a time?

This page is built around a single alarm at a time. For multiple alarms, open a separate tab for each one and set a different time in each, keeping every tab open until it's rung.
